\n\n

SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine. It can be used to format SQL or translate between 19 different dialects like DuckDB, Presto, Spark, Snowflake, and BigQuery. It aims to read a wide variety of SQL inputs and output syntactically correct SQL in the targeted dialects.

\n\n

It is a very comprehensive generic SQL parser with a robust test suite. It is also quite performant, while being written purely in Python.

\n\n

You can easily customize the parser, analyze queries, traverse expression trees, and programmatically build SQL.

\n\n

Syntax errors are highlighted and dialect incompatibilities can warn or raise depending on configurations. However, it should be noted that SQL validation is not SQLGlot\u2019s goal, so some syntax errors may go unnoticed.

\n\n

Contributions are very welcome in SQLGlot; read the contribution guide to get started!

Examples

\n\n

Formatting and Transpiling

\n\n

Easily translate from one dialect to another. For example, date/time functions vary from dialects and can be hard to deal with:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT EPOCH_MS(1618088028295)", read="duckdb", write="hive")[0]\n
\n
\n\n
\n
'SELECT FROM_UNIXTIME(1618088028295 / 1000)'\n
\n
\n\n

SQLGlot can even translate custom time formats:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT STRFTIME(x, '%y-%-m-%S')", read="duckdb", write="hive")[0]\n
\n
\n\n
\n
"SELECT DATE_FORMAT(x, 'yy-M-ss')"\n
\n
\n\n

As another example, let's suppose that we want to read in a SQL query that contains a CTE and a cast to REAL, and then transpile it to Spark, which uses backticks for identifiers and FLOAT instead of REAL:

\n\n
\n
import sqlglot\n\nsql = """WITH baz AS (SELECT a, c FROM foo WHERE a = 1) SELECT f.a, b.b, baz.c, CAST("b"."a" AS REAL) d FROM foo f JOIN bar b ON f.a = b.a LEFT JOIN baz ON f.a = baz.a"""\nprint(sqlglot.transpile(sql, write="spark", identify=True, pretty=True)[0])\n
\n
\n\n
\n
WITH `baz` AS (\n  SELECT\n    `a`,\n    `c`\n  FROM `foo`\n  WHERE\n    `a` = 1\n)\nSELECT\n  `f`.`a`,\n  `b`.`b`,\n  `baz`.`c`,\n  CAST(`b`.`a` AS FLOAT) AS `d`\nFROM `foo` AS `f`\nJOIN `bar` AS `b`\n  ON `f`.`a` = `b`.`a`\nLEFT JOIN `baz`\n  ON `f`.`a` = `baz`.`a`\n
\n
\n\n

Comments are also preserved in a best-effort basis when transpiling SQL code:

\n\n
\n
sql = """\n/* multi\n   line\n   comment\n*/\nSELECT\n  tbl.cola /* comment 1 */ + tbl.colb /* comment 2 */,\n  CAST(x AS INT), # comment 3\n  y               -- comment 4\nFROM\n  bar /* comment 5 */,\n  tbl #          comment 6\n"""\n\nprint(sqlglot.transpile(sql, read='mysql', pretty=True)[0])\n
\n
\n\n
\n
/* multi\n   line\n   comment\n*/\nSELECT\n  tbl.cola /* comment 1 */ + tbl.colb /* comment 2 */,\n  CAST(x AS INT), /* comment 3 */\n  y /* comment 4 */\nFROM bar /* comment 5 */, tbl /*          comment 6 */\n
\n
\n\n

Metadata

\n\n

You can explore SQL with expression helpers to do things like find columns and tables:

\n\n
\n
from sqlglot import parse_one, exp\n\n# print all column references (a and b)\nfor column in parse_one("SELECT a, b + 1 AS c FROM d").find_all(exp.Column):\n    print(column.alias_or_name)\n\n# find all projections in select statements (a and c)\nfor select in parse_one("SELECT a, b + 1 AS c FROM d").find_all(exp.Select):\n    for projection in select.expressions:\n        print(projection.alias_or_name)\n\n# find all tables (x, y, z)\nfor table in parse_one("SELECT * FROM x JOIN y JOIN z").find_all(exp.Table):\n    print(table.name)\n
\n
\n\n

Parser Errors

\n\n

When the parser detects an error in the syntax, it raises a ParserError:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT foo( FROM bar")\n
\n
\n\n
sqlglot.errors.ParseError: Expecting ). Line 1, Col: 13.\n  select foo( FROM bar\n              ~~~~\n
\n\n

Structured syntax errors are accessible for programmatic use:

\n\n
\n
import sqlglot\ntry:\n    sqlglot.transpile("SELECT foo( FROM bar")\nexcept sqlglot.errors.ParseError as e:\n    print(e.errors)\n
\n
\n\n
\n
[{\n  'description': 'Expecting )',\n  'line': 1,\n  'col': 13,\n  'start_context': 'SELECT foo( ',\n  'highlight': 'FROM',\n  'end_context': ' bar'\n}]\n
\n
\n\n

Unsupported Errors

\n\n

Presto APPROX_DISTINCT supports the accuracy argument which is not supported in Hive:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT APPROX_DISTINCT(a, 0.1) FROM foo", read="presto", write="hive")\n
\n
\n\n
\n
APPROX_COUNT_DISTINCT does not support accuracy\n'SELECT APPROX_COUNT_DISTINCT(a) FROM foo'\n
\n
\n\n

Build and Modify SQL

\n\n

SQLGlot supports incrementally building sql expressions:

\n\n
\n
from sqlglot import select, condition\n\nwhere = condition("x=1").and_("y=1")\nselect("*").from_("y").where(where).sql()\n
\n
\n\n
\n
'SELECT * FROM y WHERE x = 1 AND y = 1'\n
\n
\n\n

You can also modify a parsed tree:

\n\n
\n
from sqlglot import parse_one\nparse_one("SELECT x FROM y").from_("z").sql()\n
\n
\n\n
\n
'SELECT x FROM y, z'\n
\n
\n\n

There is also a way to recursively transform the parsed tree by applying a mapping function to each tree node:

\n\n
\n
from sqlglot import exp, parse_one\n\nexpression_tree = parse_one("SELECT a FROM x")\n\ndef transformer(node):\n    if isinstance(node, exp.Column) and node.name == "a":\n        return parse_one("FUN(a)")\n    return node\n\ntransformed_tree = expression_tree.transform(transformer)\ntransformed_tree.sql()\n
\n
\n\n
\n
'SELECT FUN(a) FROM x'\n
\n
\n\n

SQL Optimizer

\n\n

SQLGlot can rewrite queries into an \"optimized\" form. It performs a variety of techniques to create a new canonical AST. This AST can be used to standardize queries or provide the foundations for implementing an actual engine. For example:

\n\n
\n
import sqlglot\nfrom sqlglot.optimizer import optimize\n\nprint(\n    optimize(\n        sqlglot.parse_one("""\n            SELECT A OR (B OR (C AND D))\n            FROM x\n            WHERE Z = date '2021-01-01' + INTERVAL '1' month OR 1 = 0\n        """),\n        schema={"x": {"A": "INT", "B": "INT", "C": "INT", "D": "INT", "Z": "STRING"}}\n    ).sql(pretty=True)\n)\n
\n
\n\n
\n
SELECT\n  (\n    "x"."a" OR "x"."b" OR "x"."c"\n  ) AND (\n    "x"."a" OR "x"."b" OR "x"."d"\n  ) AS "_col_0"\nFROM "x" AS "x"\nWHERE\n  CAST("x"."z" AS DATE) = CAST('2021-02-01' AS DATE)\n
\n
\n\n

AST Introspection

\n\n

You can see the AST version of the sql by calling repr:

\n\n
\n
from sqlglot import parse_one\nprint(repr(parse_one("SELECT a + 1 AS z")))\n
\n
\n\n
\n
(SELECT expressions:\n  (ALIAS this:\n    (ADD this:\n      (COLUMN this:\n        (IDENTIFIER this: a, quoted: False)), expression:\n      (LITERAL this: 1, is_string: False)), alias:\n    (IDENTIFIER this: z, quoted: False)))\n
\n
\n\n

AST Diff

\n\n

SQLGlot can calculate the difference between two expressions and output changes in a form of a sequence of actions needed to transform a source expression into a target one:

\n\n
\n
from sqlglot import diff, parse_one\ndiff(parse_one("SELECT a + b, c, d"), parse_one("SELECT c, a - b, d"))\n
\n
\n\n
\n
[\n  Remove(expression=(ADD this:\n    (COLUMN this:\n      (IDENTIFIER this: a, quoted: False)), expression:\n    (COLUMN this:\n      (IDENTIFIER this: b, quoted: False)))),\n  Insert(expression=(SUB this:\n    (COLUMN this:\n      (IDENTIFIER this: a, quoted: False)), expression:\n    (COLUMN this:\n      (IDENTIFIER this: b, quoted: False)))),\n  Move(expression=(COLUMN this:\n    (IDENTIFIER this: c, quoted: False))),\n  Keep(source=(IDENTIFIER this: b, quoted: False), target=(IDENTIFIER this: b, quoted: False)),\n  ...\n]\n
\n
\n\n

Custom Dialects

\n\n

Dialects can be added by subclassing Dialect:

SQL Execution

\n\n

One can even interpret SQL queries using SQLGlot, where the tables are represented as Python dictionaries. Although the engine is not very fast (it's not supposed to be) and is in a relatively early stage of development, it can be useful for unit testing and running SQL natively across Python objects. Additionally, the foundation can be easily integrated with fast compute kernels (arrow, pandas). Below is an example showcasing the execution of a SELECT expression that involves aggregations and JOINs:

\n\n
\n
from sqlglot.executor import execute\n\ntables = {\n    "sushi": [\n        {"id": 1, "price": 1.0},\n        {"id": 2, "price": 2.0},\n        {"id": 3, "price": 3.0},\n    ],\n    "order_items": [\n        {"sushi_id": 1, "order_id": 1},\n        {"sushi_id": 1, "order_id": 1},\n        {"sushi_id": 2, "order_id": 1},\n        {"sushi_id": 3, "order_id": 2},\n    ],\n    "orders": [\n        {"id": 1, "user_id": 1},\n        {"id": 2, "user_id": 2},\n    ],\n}\n\nexecute(\n    """\n    SELECT\n      o.user_id,\n      SUM(s.price) AS price\n    FROM orders o\n    JOIN order_items i\n      ON o.id = i.order_id\n    JOIN sushi s\n      ON i.sushi_id = s.id\n    GROUP BY o.user_id\n    """,\n    tables=tables\n)\n
\n
\n\n
\n
user_id price\n      1   4.0\n      2   3.0\n

PySpark DataFrame SQL Generator

\n\n

This is a drop-in replacement for the PySpark DataFrame API that will generate SQL instead of executing DataFrame operations directly. This, when combined with the transpiling support in SQLGlot, allows one to write PySpark DataFrame code and execute it on other engines like DuckDB, Presto, Spark, Snowflake, and BigQuery.

\n\n

Currently many of the common operations are covered and more functionality will be added over time. Please open an issue or PR with your feedback or contribution to help influence what should be prioritized next and make sure your use case is properly supported.

\n\n

How to use

\n\n

Instructions

\n\n
    \n
  • Install SQLGlot and that is all that is required to just generate SQL. The examples show generating SQL and then executing that SQL on a specific engine and that will require that engine's client library.
    • \n
  • Find/replace all from pyspark.sql with from sqlglot.dataframe.
    • \n
  • Prior to any spark.read.table or spark.table run sqlglot.schema.add_table('<table_name>', <column_structure>).\n
      \n
    • The column structure can be defined the following ways:\n
        \n
      • Dictionary where the keys are column names and values are string of the Spark SQL type name.\n
          \n
        • Ex: {'cola': 'string', 'colb': 'int'}
          • \n
        • \n
      • PySpark DataFrame StructType similar to when using createDataFrame.\n
          \n
        • Ex: StructType([StructField('cola', StringType()), StructField('colb', IntegerType())])
          • \n
        • \n
      • A string of names and types similar to what is supported in createDataFrame.\n
          \n
        • Ex: cola: STRING, colb: INT
          • \n
        • \n
      • [Not Recommended] A list of string column names without type.\n
          \n
        • Ex: ['cola', 'colb']
          • \n
        • The lack of types may limit functionality in future releases.
          • \n
        • \n
      • \n
    • See Registering Custom Schema for information on how to skip this step if the information is stored externally.
      • \n
    • \n
  • Add .sql(pretty=True) to your final DataFrame command to return a list of sql statements to run that command.\n
      \n
    • In most cases a single SQL statement is returned. Currently the only exception is when caching DataFrames which isn't supported in other dialects.
      • \n
    • Spark is the default output dialect. See dialects for a full list of dialects.
      • \n
    • Ex: .sql(pretty=True, dialect='bigquery')
      • \n
    • \n
\n\n

Examples

\n\n
\n
import sqlglot\nfrom sqlglot.dataframe.sql.session import SparkSession\nfrom sqlglot.dataframe.sql import functions as F\n\nsqlglot.schema.add_table('employee', {\n  'employee_id': 'INT',\n  'fname': 'STRING',\n  'lname': 'STRING',\n  'age': 'INT',\n})  # Register the table structure prior to reading from the table\n\nspark = SparkSession()\n\ndf = (\n    spark\n    .table('employee')\n    .groupBy(F.col("age"))\n    .agg(F.countDistinct(F.col("employee_id")).alias("num_employees")) \n)\n\nprint(df.sql(pretty=True))  # Spark will be the dialect used by default\n
\n
\n\n
SELECT\n  `employee`.`age` AS `age`,\n  COUNT(DISTINCT `employee`.`employee_id`) AS `num_employees`\nFROM `employee` AS `employee`\nGROUP BY\n  `employee`.`age`\n
\n\n

Registering Custom Schema Class

\n\n

The step of adding sqlglot.schema.add_table can be skipped if you have the column structure stored externally like in a file or from an external metadata table. This can be done by writing a class that implements the sqlglot.schema.Schema abstract class and then assigning that class to sqlglot.schema.

\n\n
\n
import sqlglot\nfrom sqlglot.dataframe.sql.session import SparkSession\nfrom sqlglot.dataframe.sql import functions as F\nfrom sqlglot.schema import Schema\n\n\nclass ExternalSchema(Schema):\n  ...\n\nsqlglot.schema = ExternalSchema()\n\nspark = SparkSession()\n\ndf = (\n    spark\n    .table('employee')\n    .groupBy(F.col("age"))\n    .agg(F.countDistinct(F.col("employee_id")).alias("num_employees")) \n)\n\nprint(df.sql(pretty=True))\n

Unsupportable Operations

\n\n

Any operation that lacks a way to represent it in SQL cannot be supported by this tool. An example of this would be rdd operations. Since the DataFrame API though is mostly modeled around SQL concepts most operations can be supported.

Functionality Difference: If you provide a value to replace a null and that type conflicts\nwith the type of the column then PySpark will just ignore your replacement.\nThis will try to cast them to be the same in some cases. So they won't always match.\nBest to not mix types so make sure replacement is the same type as the column

\n\n

Possibility for improvement: Use typeof function to get the type of the column\nand check if it matches the type of the value provided. If not then make it null.

Dialects

\n\n

While there is a SQL standard, most SQL engines support a variation of that standard. This makes it difficult\nto write portable SQL code. SQLGlot bridges all the different variations, called \"dialects\", with an extensible\nSQL transpilation framework.

\n\n

The base sqlglot.dialects.dialect.Dialect class implements a generic dialect that aims to be as universal as possible.

\n\n

Each SQL variation has its own Dialect subclass, extending the corresponding Tokenizer, Parser and Generator\nclasses as needed.

\n\n

Implementing a custom Dialect

\n\n

Consider the following example:

\n\n
\n
from sqlglot import exp\nfrom sqlglot.dialects.dialect import Dialect\nfrom sqlglot.generator import Generator\nfrom sqlglot.tokens import Tokenizer, TokenType\n\n\nclass Custom(Dialect):\n    class Tokenizer(Tokenizer):\n        QUOTES = ["'", '"']\n        IDENTIFIERS = ["`"]\n\n        KEYWORDS = {\n            **Tokenizer.KEYWORDS,\n            "INT64": TokenType.BIGINT,\n            "FLOAT64": TokenType.DOUBLE,\n        }\n\n    class Generator(Generator):\n        TRANSFORMS = {exp.Array: lambda self, e: f"[{self.expressions(e)}]"}\n\n        TYPE_MAPPING = {\n            exp.DataType.Type.TINYINT: "INT64",\n            exp.DataType.Type.SMALLINT: "INT64",\n            exp.DataType.Type.INT: "INT64",\n            exp.DataType.Type.BIGINT: "INT64",\n            exp.DataType.Type.DECIMAL: "NUMERIC",\n            exp.DataType.Type.FLOAT: "FLOAT64",\n            exp.DataType.Type.DOUBLE: "FLOAT64",\n            exp.DataType.Type.BOOLEAN: "BOOL",\n            exp.DataType.Type.TEXT: "STRING",\n        }\n
\n
\n\n

This is a typical example of adding a new dialect implementation in SQLGlot: we specify its identifier and string\ndelimiters, as well as what tokens it uses for its types and how they're associated with SQLGlot types. Since\nthe Expression classes are common for each dialect supported in SQLGlot, we may also need to override the generation\nlogic for some expressions; this is usually done by adding new entries to the TRANSFORMS mapping.

Semantic Diff for SQL

\n\n

by Iaroslav Zeigerman

\n\n

Motivation

\n\n

Software is constantly changing and evolving, and identifying what has changed and reviewing those changes is an integral part of the development process. SQL code is no exception to this.

\n\n

Text-based diff tools such as git diff, when applied to a code base, have certain limitations. First, they can only detect insertions and deletions, not movements or updates of individual pieces of code. Second, such tools can only detect changes between lines of text, which is too coarse for something as granular and detailed as source code. Additionally, the outcome of such a diff is dependent on the underlying code formatting, and yields different results if the formatting should change.

\n\n

Consider the following diff generated by Git:

\n\n

\"Git

\n\n

Semantically the query hasn\u2019t changed. The two arguments b and c have been swapped (moved), posing no impact on the output of the query. Yet Git replaced the whole affected expression alongside a bulk of unrelated elements.

\n\n

The alternative to text-based diffing is to compare Abstract Syntax Trees (AST) instead. The main advantage of ASTs are that they are a direct product of code parsing, which represents the underlying code structure at any desired level of granularity. Comparing ASTs may yield extremely precise diffs; changes such as code movements and updates can also be detected. Even more importantly, this approach facilitates additional use cases beyond eyeballing two versions of source code side by side.

\n\n

The use cases I had in mind for SQL when I decided to embark on this journey of semantic diffing were the following:

\n\n
    \n
  • Query similarity score. Identifying which parts the two queries have in common to automatically suggest opportunities for consolidation, creation of intermediate/staging tables, and so on.
    • \n
  • Differentiating between cosmetic / structural changes and functional ones. For example when a nested query is refactored into a common table expression (CTE), this kind of change doesn\u2019t have any functional impact on either a query or its outcome.
    • \n
  • Automatic suggestions about the need to retroactively backfill data. This is especially important for pipelines that populate very large tables for which restatement is a runtime-intensive procedure. The ability to discern between simple code movements and actual modifications can help assess the impact of a change and make suggestions accordingly.
    • \n
\n\n

The implementation discussed in this post is now a part of the SQLGlot library. You can find a complete source code in the diff.py module. The choice of SQLglot was an obvious one due to its simple but powerful API, lack of external dependencies and, more importantly, extensive list of supported SQL dialects.

\n\n

The Search for a Solution

\n\n

When it comes to any diffing tool (not just a semantic one), the primary challenge is to match as many elements of compared entities as possible. Once such a set of matching elements is available, deriving a sequence of changes becomes an easy task.

\n\n

If our elements have unique identifiers associated with them (for example, an element\u2019s ID in DOM), the matching problem is trivial. However, the SQL syntax trees that we are comparing have neither unique keys nor object identifiers that can be used for the purposes of matching. So, how do we suppose to find pairs of nodes that are related?

\n\n

To better illustrate the problem, consider comparing the following SQL expressions: SELECT a + b + c, d, e and SELECT a - b + c, e, f. Matching individual nodes from respective syntax trees can be visualized as follows:

\n\n

\"Figure\nFigure 1: Example of node matching for two SQL expression trees.

\n\n

By looking at the figure of node matching for two SQL expression trees above, we conclude that the following changes should be captured by our solution:

\n\n
    \n
  • Inserted nodes: Sub and f. These are the nodes from the target AST which do not have a matching node in the source AST.
    • \n
  • Removed nodes: Add and d. These are the nodes from the source AST which do not have a counterpart in the target AST.
    • \n
  • Remaining nodes must be identified as unchanged.
    • \n
\n\n

It should be clear at this point that if we manage to match nodes in the source tree with their counterparts in the target tree, then computing the diff becomes a trivial matter.

\n\n

Na\u00efve Brute-Force

\n\n

The na\u00efve solution would be to try all different permutations of node pair combinations, and see which set of pairs performs the best based on some type of heuristics. The runtime cost of such a solution quickly reaches the escape velocity; if both trees had only 10 nodes each, the number of such sets would approximately be 10! ^ 2 = 3.6M ^ 2 ~= 13 * 10^12. This is a very bad case of factorial complexity (to be precise, it\u2019s actually much worse - O(n! ^ 2) - but I couldn\u2019t come up with a name for it), so there is little need to explore this approach any further.

\n\n

Myers Algorithm

\n\n

After the na\u00efve approach was proven to be infeasible, the next question I asked myself was \u201chow does git diff work?\u201d. This question led me to discover the Myers diff algorithm [1]. This algorithm has been designed to compare sequences of strings. At its core, it\u2019s looking for the shortest path on a graph of possible edits that transform the first sequence into the second one, while heavily rewarding those paths that lead to longest subsequences of unchanged elements. There\u2019s a lot of material out there describing this algorithm in greater detail. I found James Coglan\u2019s series of blog posts to be the most comprehensive.

\n\n

Therefore, I had this \u201cbrilliant\u201d (actually not) idea to transform trees into sequences by traversing them in topological order, and then applying the Myers algorithm on resulting sequences while using a custom heuristics when checking the equality of two nodes. Unsurprisingly, comparing sequences of strings is quite different from comparing hierarchical tree structures, and by flattening trees into sequences, we lose a lot of relevant context. This resulted in a terrible performance of this algorithm on ASTs. It often matched completely unrelated nodes, even when the two trees were mostly the same, and produced extremely inaccurate lists of changes overall. After playing around with it a little and tweaking my equality heuristics to improve accuracy, I ultimately scrapped the whole implementation and went back to the drawing board.

\n\n

Change Distiller

\n\n

The algorithm I settled on at the end was Change Distiller, created by Fluri et al. [2], which in turn is an improvement over the core idea described by Chawathe et al. [3].

\n\n

The algorithm consists of two high-level steps:

\n\n
    \n
  1. Finding appropriate matchings between pairs of nodes that are part of compared ASTs. Identifying what is meant by \u201cappropriate\u201d matching is also a part of this step.
    2. \n
  2. Generating the so-called \u201cedit script\u201d from the matching set built in the 1st step. The edit script is a sequence of edit operations (for example, insert, remove, update, etc.) on individual tree nodes, such that when applied as transformations on the source AST, it eventually becomes the target AST. In general, the shorter the sequence, the better. The length of the edit script can be used to compare the performance of different algorithms, though this is not the only metric that matters.
    3. \n
\n\n

The rest of this section is dedicated to the Python implementation of the steps above using the AST implementation provided by the SQLGlot library.

\n\n

Building the Matching Set

\n\n

Matching Leaves

\n\n

We begin composing the matching set by matching the leaf nodes. Leaf nodes are the nodes that do not have any children nodes (such as literals, identifiers, etc.). In order to match them, we gather all the leaf nodes from the source tree and generate a cartesian product with all the leaves from the target tree, while comparing pairs created this way and assigning them a similarity score. During this stage, we also exclude pairs that don\u2019t pass basic matching criteria. Then, we pick pairs that scored the highest while making sure that each node is matched no more than once.

\n\n

Using the example provided at the beginning of the post, the process of building an initial set of candidate matchings can be seen on Figure 2.

\n\n

\"Figure\nFigure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes.

\n\n

First, let\u2019s analyze the similarity score. Then, we\u2019ll discuss matching criteria.

\n\n

The similarity score proposed by Fluri et al. [2] is a dice coefficient applied to bigrams of respective node values. A bigram is a sequence of two adjacent elements from a string computed in a sliding window fashion:

\n\n
\n
def bigram(string):\n    count = max(0, len(string) - 1)\n    return [string[i : i + 2] for i in range(count)]\n
\n
\n\n

For reasons that will become clear shortly, we actually need to compute bigram histograms rather than just sequences:

\n\n
\n
from collections import defaultdict\n\ndef bigram_histo(string):\n    count = max(0, len(string) - 1)\n    bigram_histo = defaultdict(int)\n    for i in range(count):\n        bigram_histo[string[i : i + 2]] += 1\n    return bigram_histo\n
\n
\n\n

The dice coefficient formula looks like following:

\n\n

\"Dice

\n\n

Where X is a bigram of the source node and Y is a bigram of the second one. What this essentially does is count the number of bigram elements the two nodes have in common, multiply it by 2, and then divide by the total number of elements in both bigrams. This is where bigram histograms come in handy:

\n\n
\n
def dice_coefficient(source, target):\n    source_histo = bigram_histo(source.sql())\n    target_histo = bigram_histo(target.sql())\n\n    total_grams = (\n        sum(source_histo.values()) + sum(target_histo.values())\n    )\n    if not total_grams:\n        return 1.0 if source == target else 0.0\n\n    overlap_len = 0\n    overlapping_grams = set(source_histo) & set(target_histo)\n    for g in overlapping_grams:\n        overlap_len += min(source_histo[g], target_histo[g])\n\n    return 2 * overlap_len / total_grams\n
\n
\n\n

To compute a bigram given a tree node, we first transform the node into its canonical SQL representation,so that the Literal(123) node becomes just \u201c123\u201d and the Identifier(\u201ca\u201d) node becomes just \u201ca\u201d. We also handle a scenario when strings are too short to derive bigrams. In this case, we fallback to checking the two nodes for equality.

\n\n

Now when we know how to compute the similarity score, we can take care of the matching criteria for leaf nodes. In the original paper [2], the matching criteria is formalized as follows:

\n\n

\"Matching

\n\n

The two nodes are matched if two conditions are met:

\n\n
    \n
  1. The node labels match (in our case labels are just node types).
    2. \n
  2. The similarity score for node values is greater than or equal to some threshold \u201cf\u201d. The authors of the paper recommend setting the value of \u201cf\u201d to 0.6.
    3. \n
\n\n

With building blocks in place, we can now build a matching set for leaf nodes. First, we generate a list of candidates for matching:

\n\n
\n
from heapq import heappush, heappop\n\ncandidate_matchings = []\nsource_leaves = _get_leaves(self._source)\ntarget_leaves = _get_leaves(self._target)\nfor source_leaf in source_leaves:\n    for target_leaf in target_leaves:\n        if _is_same_type(source_leaf, target_leaf):\n            similarity_score = dice_coefficient(\n                source_leaf, target_leaf\n            )\n            if similarity_score >= 0.6:\n                heappush(\n                    candidate_matchings,\n                    (\n                        -similarity_score,\n                        len(candidate_matchings),\n                        source_leaf,\n                        target_leaf,\n                    ),\n                )\n
\n
\n\n

In the implementation above, we push each matching pair onto the heap to automatically maintain the correct order based on the assigned similarity score.

\n\n

Finally, we build the initial matching set by picking leaf pairs with the highest score:

\n\n
\n
matching_set = set()\nwhile candidate_matchings:\n    _, _, source_leaf, target_leaf = heappop(candidate_matchings)\n    if (\n        source_leaf in unmatched_source_nodes\n        and target_leaf in unmatched_target_nodes\n    ):\n        matching_set.add((source_leaf, target_leaf))\n        unmatched_source_nodes.remove(source_leaf)\n        unmatched_target_nodes.remove(target_leaf)\n
\n
\n\n

To finalize the matching set, we should now proceed with matching inner nodes.

\n\n

Matching Inner Nodes

\n\n

Matching inner nodes is quite similar to matching leaf nodes, with the following two distinctions:

\n\n
    \n
  • Rather than ranking a set of possible candidates, we pick the first node pair that passes the matching criteria.
    • \n
  • The matching criteria itself has been extended to account for the number of leaf nodes the pair of inner nodes have in common.
    • \n
\n\n

\"Figure\nFigure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched.

\n\n

Let\u2019s start with the matching criteria. The criteria is formalized as follows:

\n\n

\"Matching

\n\n

Alongside already familiar similarity score and node type criteria, there is a new one in the middle: the ratio of leaf nodes that the two nodes have in common must exceed some threshold \u201ct\u201d. The recommended value for \u201ct\u201d is also 0.6. Counting the number of common leaf nodes is pretty straightforward, since we already have the complete matching set for leaves. All we need to do is count how many matching pairs do leaf nodes from the two compared inner nodes form.

\n\n

There are two additional heuristics associated with this matching criteria:

\n\n
    \n
  • Inner node similarity weighting: if the similarity score between the node values doesn\u2019t pass the threshold \u201cf\u201d but the ratio of common leaf nodes (\u201ct\u201d) is greater than or equal to 0.8, then the matching is considered successful.
    • \n
  • The threshold \u201ct\u201d is reduced to 0.4 for inner nodes with the number of leaf nodes equal to 4 or less, in order to decrease the false negative rate for small subtrees.
    • \n
\n\n

We now only have to iterate through the remaining unmatched nodes and form matching pairs based on the outlined criteria:

\n\n
\n
leaves_matching_set = matching_set.copy()\n\nfor source_node in unmatched_source_nodes.copy():\n    for target_node in unmatched_target_nodes:\n        if _is_same_type(source_node, target_node):\n            source_leaves = set(_get_leaves(source_node))\n            target_leaves = set(_get_leaves(target_node))\n\n            max_leaves_num = max(len(source_leaves), len(target_leaves))\n            if max_leaves_num:\n                common_leaves_num = sum(\n                    1 if s in source_leaves and t in target_leaves else 0\n                    for s, t in leaves_matching_set\n                )\n                leaf_similarity_score = common_leaves_num / max_leaves_num\n            else:\n                leaf_similarity_score = 0.0\n\n            adjusted_t = (\n                0.6\n                if min(len(source_leaves), len(target_leaves)) > 4\n                else 0.4\n            )\n\n            if leaf_similarity_score >= 0.8 or (\n                leaf_similarity_score >= adjusted_t\n                and dice_coefficient(source_node, target_node) >= 0.6\n            ):\n                matching_set.add((source_node, target_node))\n                unmatched_source_nodes.remove(source_node)\n                unmatched_target_nodes.remove(target_node)\n                break\n
\n
\n\n

After the matching set is formed, we can proceed with generation of the edit script, which will be the algorithm\u2019s output.

\n\n

Generating the Edit Script

\n\n

At this point, we should have the following 3 sets at our disposal:

\n\n
    \n
  • The set of matched node pairs.
    • \n
  • The set of remaining unmatched nodes from the source tree.
    • \n
  • The set of remaining unmatched nodes from the target tree.
    • \n
\n\n

We can derive 3 kinds of edits from the matching set: either the node\u2019s value was updated (Update), the node was moved to a different position within the tree (Move), or the node remained unchanged (Keep). Note that the Move case is not mutually exclusive with the other two. The node could have been updated or could have remained the same while at the same time its position within its parent node or the parent node itself could have changed. All unmatched nodes from the source tree are the ones that were removed (Remove), while unmatched nodes from the target tree are the ones that were inserted (Insert).

\n\n

The latter two cases are pretty straightforward to implement:

\n\n
\n
edit_script = []\n\nfor removed_node in unmatched_source_nodes:\n    edit_script.append(Remove(removed_node))\nfor inserted_node in unmatched_target_nodes:\n    edit_script.append(Insert(inserted_node))\n
\n
\n\n

Traversing the matching set requires a little more thought:

\n\n
\n
for source_node, target_node in matching_set:\n    if (\n        not isinstance(source_node, LEAF_EXPRESSION_TYPES)\n        or source_node == target_node\n    ):\n        move_edits = generate_move_edits(\n            source_node, target_node, matching_set\n        )\n        edit_script.extend(move_edits)\n        edit_script.append(Keep(source_node, target_node))\n    else:\n        edit_script.append(Update(source_node, target_node))\n
\n
\n\n

If a matching pair represents a pair of leaf nodes, we check if they are the same to decide whether an update took place. For inner node pairs, we also need to compare the positions of their respective children to detect node movements. Chawathe et al. [3] suggest applying the longest common subsequence (LCS) algorithm which, no surprise here, was described by Myers himself [1]. There is a small catch, however: instead of checking the equality of two children nodes, we need to check whether the two nodes form a pair that is a part of our matching set.

\n\n

Now with this knowledge, the implementation becomes straightforward:

\n\n
\n
def generate_move_edits(source, target, matching_set):\n    source_children = _get_child_nodes(source)\n    target_children = _get_child_nodes(target)\n\n    lcs = set(\n        _longest_common_subsequence(\n            source_children,\n            target_children,\n            lambda l, r: (l, r) in matching_set\n        )\n    )\n\n    move_edits = []\n    for node in source_children:\n        if node not in lcs and node not in unmatched_source_nodes:\n            move_edits.append(Move(node))\n\n    return move_edits\n
\n
\n\n

I left out the implementation of the LCS algorithm itself here, but there are plenty of implementation choices out there that can be easily looked up.

\n\n

Output

\n\n

The implemented algorithm produces the output that resembles the following:

\n\n
\n
>>> from sqlglot import parse_one, diff\n>>> diff(parse_one("SELECT a + b + c, d, e"), parse_one("SELECT a - b + c, e, f"))\n\nRemove(Add)\nRemove(Column(d))\nRemove(Identifier(d))\nInsert(Sub)\nInsert(Column(f))\nInsert(Identifier(f))\nKeep(Select, Select)\nKeep(Add, Add)\nKeep(Column(a), Column(a))\nKeep(Identifier(a), Identifier(a))\nKeep(Column(b), Column(b))\nKeep(Identifier(b), Identifier(b))\nKeep(Column(c), Column(c))\nKeep(Identifier(c), Identifier(c))\nKeep(Column(e), Column(e))\nKeep(Identifier(e), Identifier(e))\n
\n
\n\n

Note that the output above is abbreviated. The string representation of actual AST nodes is significantly more verbose.

\n\n

The implementation works especially well when coupled with the SQLGlot\u2019s query optimizer which can be used to produce canonical representations of compared queries:

\n\n
\n
>>> schema={"t": {"a": "INT", "b": "INT", "c": "INT", "d": "INT"}}\n>>> source = """\n... SELECT 1 + 1 + a\n... FROM t\n... WHERE b = 1 OR (c = 2 AND d = 3)\n... """\n>>> target = """\n... SELECT 2 + a\n... FROM t\n... WHERE (b = 1 OR c = 2) AND (b = 1 OR d = 3)\n... """\n>>> optimized_source = optimize(parse_one(source), schema=schema)\n>>> optimized_target = optimize(parse_one(target), schema=schema)\n>>> edit_script = diff(optimized_source, optimized_target)\n>>> sum(0 if isinstance(e, Keep) else 1 for e in edit_script)\n0\n
\n
\n\n

Optimizations

\n\n

The worst case runtime complexity of this algorithm is not exactly stellar: O(n^2 * log n^2). This is because of the leaf matching process, which involves ranking a cartesian product between all leaf nodes of compared trees. Unsurprisingly, the algorithm takes a considerable time to finish for bigger queries.

\n\n

There are still a few basic things we can do in our implementation to help improve performance:

\n\n
    \n
  • Refer to individual node objects using their identifiers (Python\u2019s id()) instead of direct references in sets. This helps avoid costly recursive hash calculations and equality checks.
    • \n
  • Cache bigram histograms to avoid computing them more than once for the same node.
    • \n
  • Compute the canonical SQL string representation for each tree once while caching string representations of all inner nodes. This prevents redundant tree traversals when bigrams are computed.
    • \n
\n\n

At the time of writing only the first two optimizations have been implemented, so there is an opportunity to contribute for anyone who\u2019s interested.

\n\n

Alternative Solutions

\n\n

This section is dedicated to solutions that I\u2019ve investigated, but haven\u2019t tried.

\n\n

First, this section wouldn\u2019t be complete without Tristan Hume\u2019s blog post. Tristan\u2019s solution has a lot in common with the Myers algorithm plus heuristics that is much more clever than what I came up with. The implementation relies on a combination of dynamic programming and A* search algorithm to explore the space of possible matchings and pick the best ones. It seemed to have worked well for Tistan\u2019s specific use case, but after my negative experience with the Myers algorithm, I decided to try something different.

\n\n

Another notable approach is the Gumtree algorithm by Falleri et al. [4]. I discovered this paper after I\u2019d already implemented the algorithm that is the main focus of this post. In sections 5.2 and 5.3 of their paper, the authors compare the two algorithms side by side and claim that Gumtree is significantly better in terms of both runtime performance and accuracy when evaluated on 12 792 pairs of Java source files. This doesn\u2019t surprise me, as the algorithm takes the height of subtrees into account. In my tests, I definitely saw scenarios in which this context would have helped. On top of that, the authors promise O(n^2) runtime complexity in the worst case which, given the Change Distiller's O(n^2 * log n^2), looks particularly tempting. I hope to try this algorithm out at some point, and there is a good chance you see me writing about it in my future posts.

\n\n

Conclusion

\n\n

The Change Distiller algorithm yielded quite satisfactory results in most of my tests. The scenarios in which it fell short mostly concerned identical (or very similar) subtrees located in different parts of the AST. In those cases, node mismatches were frequent and, as a result, edit scripts were somewhat suboptimal.

\n\n

Additionally, the runtime performance of the algorithm leaves a lot to be desired. On trees with 1000 leaf nodes each, the algorithm takes a little under 2 seconds to complete. My implementation still has room for improvement, but this should give you a rough idea of what to expect. It appears that the Gumtree algorithm [4] can help address both of these points. I hope to find bandwidth to work on it soon and then compare the two algorithms side-by-side to find out which one performs better on SQL specifically. In the meantime, Change Distiller definitely gets the job done, and I can now proceed with applying it to some of the use cases I mentioned at the beginning of this post.

\n\n

I\u2019m also curious to learn whether other folks in the industry faced a similar problem, and how they approached it. If you did something similar, I\u2019m interested to hear about your experience.

Writing a Python SQL engine from scratch

\n\n

Toby Mao

\n\n

Introduction

\n\n

When I first started writing SQLGlot in early 2021, my goal was just to translate SQL queries from SparkSQL to Presto and vice versa. However, over the last year and a half, I've ended up with a full-fledged SQL engine. SQLGlot can now parse and transpile between 18 SQL dialects and can execute all 24 TPC-H SQL queries. The parser and engine are all written from scratch using Python.

\n\n

This post will cover why I went through the effort of creating a Python SQL engine and how a simple query goes from a string to actually transforming data. The following steps are briefly summarized:

\n\n\n\n

Why?

\n\n

I started working on SQLGlot because of my work on the experimentation and metrics platform at Netflix, where I built tools that allowed data scientists to define and compute SQL-based metrics. Netflix relied on multiple engines to query data (Spark, Presto, and Druid), so my team built the metrics platform around PyPika, a Python SQL query builder. This way, definitions could be reused across multiple engines. However, it became quickly apparent that writing python code to programmatically generate SQL was challenging for data scientists, especially those with academic backgrounds, since they were mostly familiar with R and SQL. At the time, the only Python SQL parser was sqlparse, which is not actually a parser but a tokenizer, so having users write raw SQL into the platform wasn't really an option. Some time later, I randomly stumbled across Crafting Interpreters and realized that I could use it as a guide towards creating my own SQL parser/transpiler.

\n\n

Why did I do this? Isn't a Python SQL engine going to be extremely slow?

\n\n

The main reason why I ended up building a SQL engine was...just for entertainment. It's been fun learning about all the things required to actually run a SQL query, and seeing it actually work is extremely rewarding. Before SQLGlot, I had zero experience with lexers, parsers, or compilers.

\n\n

In terms of practical use cases, I planned to use the Python SQL engine for unit testing SQL pipelines. Big data pipelines are tough to test because many of the engines are not open source and cannot be run locally. With SQLGlot, you can take a SQL query targeting a warehouse such as Snowflake and seamlessly run it in CI on mock Python data. It's easy to mock data and create arbitrary UDFs because everything is just Python. Although the implementation is slow and unsuitable for large amounts of data (> 1 million rows), there's very little overhead/startup and you can run queries on test data in a couple of milliseconds.

\n\n

Finally, the components that have been built to support execution can be used as a foundation for a faster engine. I'm inspired by what Apache Calcite has done for the JVM world. Even though Python is commonly used for data, there hasn't been a Calcite for Python. So, you could say that SQLGlot aims to be that framework. For example, it wouldn't take much work to replace the Python execution engine with numpy/pandas/arrow to become a respectably-performing query engine. The implementation would be able to leverage the parser, optimizer, and logical planner, only needing to implement physical execution. There is a lot of work in the Python ecosystem around high performance vectorized computation, which I think could benefit from a pure Python-based AST/plan. Parsing and planning doesn't have to be fast when the bottleneck of running queries is processing terabytes of data. So, having a Python-based ecosystem around SQL is beneficial given the ease of development in Python, despite not having bare metal performance.

\n\n

Parts of SQLGlot's toolkit are being used today by the following:

\n\n
    \n
  • Ibis: A Python library that provides a lightweight, universal interface for data wrangling.\n
      \n
    • Uses the Python SQL expression builder and leverages the optimizer/planner to convert SQL into dataframe operations.
      • \n
    • \n
  • mysql-mimic: Pure-Python implementation of the MySQL server wire protocol\n
      \n
    • Parses / transforms SQL and executes INFORMATION_SCHEMA queries.
      • \n
    • \n
  • Quokka: Push-based vectorized query engine\n
      \n
    • Parse and optimizes SQL.
      • \n
    • \n
  • Splink: Fast, accurate and scalable probabilistic data linkage using your choice of SQL backend.\n
      \n
    • Transpiles queries.
      • \n
    • \n
\n\n

How?

\n\n

There are many steps involved with actually running a simple query like:

\n\n
\n
SELECT\n  bar.a,\n  b + 1 AS b\nFROM bar\nJOIN baz\n  ON bar.a = baz.a\nWHERE bar.a > 1\n
\n
\n\n

In this post, I'll walk through all the steps SQLGlot takes to run this query over Python objects.

\n\n

Tokenizing

\n\n

The first step is to convert the sql string into a list of tokens. SQLGlot's tokenizer is quite simple and can be found here. In a while loop, it checks each character and either appends the character to the current token, or makes a new token.

\n\n

Running the SQLGlot tokenizer shows the output.

\n\n

\"Tokenizer

\n\n

Each keyword has been converted to a SQLGlot Token object. Each token has some metadata associated with it, like line/column information for error messages. Comments are also a part of the token, so that comments can be preserved.

\n\n

Parsing

\n\n

Once a SQL statement is tokenized, we don't need to worry about white space and other formatting, so it's easier to work with. We can now convert the list of tokens into an AST. The SQLGlot parser is a handwritten recursive descent parser.

\n\n

Similar to the tokenizer, it consumes the tokens sequentially, but it instead uses a recursive algorithm. The tokens are converted into a single AST node that presents the SQL query. The SQLGlot parser was designed to support various dialects, so it contains many options for overriding parsing functionality.

\n\n

\"Parser

\n\n

The AST is a generic representation of a given SQL query. Each dialect can override or implement its own generator, which can convert an AST object into syntatically-correct SQL.

\n\n

Optimizing

\n\n

Once we have our AST, we can transform it into an equivalent query that produces the same results more efficiently. When optimizing queries, most engines first convert the AST into a logical plan and then optimize the plan. However, I chose to optimize the AST directly for the following reasons:

\n\n
    \n

  1. It's easier to debug and validate the optimizations when the input and output are both SQL.

    2. \n

  2. Rules can be applied a la carte to transform SQL into a more desirable form.

    3. \n

  3. I wanted a way to generate 'canonical sql'. Having a canonical representation of SQL is useful for understanding if two queries are semantically equivalent (e.g. SELECT 1 + 1 and SELECT 2).

    4. \n
\n\n

I've yet to find another engine that takes this approach, but I'm quite happy with this decision. The optimizer currently does not perform any \"physical optimizations\" such as join reordering. Those are left to the execution layer, as additional statistics and information could become relevant.

\n\n

\"Optimizer

\n\n

The optimizer currently has 17 rules. Each of these rules is applied, transforming the AST in place. The combination of these rules creates \"canonical\" sql that can then be more easily converted into a logical plan and executed.

\n\n

Some example rules are:

\n\n

qualify_tables and qualify_columns

\n\n
    \n
  • Adds all db/catalog qualifiers to tables and forces an alias.
    • \n
  • Ensure each column is unambiguous and expand stars.
    • \n
\n\n
\n
SELECT * FROM x;\n\nSELECT "db"."x" AS "x";\n
\n
\n\n

simplify

\n\n

Boolean and math simplification. Check out all the test cases.

\n\n
\n
((NOT FALSE) AND (x = x)) AND (TRUE OR 1 <> 3);\nx = x;\n\n1 + 1;\n2;\n
\n
\n\n

normalize

\n\n

Attempts to convert all predicates into conjunctive normal form.

\n\n
\n
-- DNF\n(A AND B) OR (B AND C AND D);\n\n-- CNF\n(A OR C) AND (A OR D) AND B;\n
\n
\n\n

unnest_subqueries

\n\n

Converts subqueries in predicates into joins.

\n\n
\n
-- The subquery can be converted into a left join\nSELECT *\nFROM x AS x\nWHERE (\n  SELECT y.a AS a\n  FROM y AS y\n  WHERE x.a = y.a\n) = 1;\n\nSELECT *\nFROM x AS x\nLEFT JOIN (\n  SELECT y.a AS a\n  FROM y AS y\n  WHERE TRUE\n  GROUP BY y.a\n) AS "_u_0"\n  ON x.a = "_u_0".a\nWHERE ("_u_0".a = 1 AND NOT "_u_0".a IS NULL)\n
\n
\n\n

pushdown_predicates

\n\n

Push down filters into the innermost query.

\n\n
\n
SELECT *\nFROM (\n  SELECT *\n  FROM x AS x\n) AS y\nWHERE y.a = 1;\n\nSELECT *\nFROM (\n  SELECT *\n  FROM x AS x\n  WHERE y.a = 1\n) AS y WHERE TRUE\n
\n
\n\n

annotate_types

\n\n

Infer all types throughout the AST given schema information and function type definitions.

\n\n

Planning

\n\n

After the SQL AST has been \"optimized\", it's much easier to convert into a logical plan. The AST is traversed and converted into a DAG consisting of one of five steps. The different steps are:

\n\n

Scan

\n\n

Selects columns from a table, applies projections, and finally filters the table.

\n\n

Sort

\n\n

Sorts a table for order by expressions.

\n\n

Set

\n\n

Applies the operators union/union all/except/intersect.

\n\n

Aggregate

\n\n

Applies an aggregation/group by.

\n\n

Join

\n\n

Joins multiple tables together.

\n\n

\"Planner

\n\n

The logical plan is quite simple and contains the information required to convert it into a physical plan (execution).

\n\n

Executing

\n\n

Finally, we can actually execute the SQL query. The Python engine is not fast, but it's very small (~400 LOC)! It iterates the DAG with a queue and runs each step, passing each intermediary table to the next step.

\n\n

In order to keep things simple, it evaluates expressions with eval. Because SQLGlot was built primarily to be a transpiler, it was simple to create a \"Python SQL\" dialect. So a SQL expression x + 1 can just be converted into scope['x'] + 1.

\n\n

\"Executor

\n\n

What's next

\n\n

SQLGlot's main focus will always be on parsing/transpiling, but I plan to continue development on the execution engine. I'd like to pass TPC-DS. If someone doesn't beat me to it, I may even take a stab at writing a Pandas/Arrow execution engine.

\n\n

I'm hoping that over time, SQLGlot will spark the Python SQL ecosystem just like Calcite has for Java.

\n\n

Special thanks

\n\n

SQLGlot would not be what it is without it's core contributors. In particular, the execution engine would not exist without Barak Alon and George Sittas.

Abstract base class for generic types.

\n\n

A generic type is typically declared by inheriting from\nthis class parameterized with one or more type variables.\nFor example, a generic mapping type might be defined as::

\n\n

class Mapping(Generic[KT, VT]):\n def __getitem__(self, key: KT) -> VT:\n ...\n # Etc.

\n\n

This class can then be used as follows::

\n\n

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT:\n try:\n return mapping[key]\n except KeyError:\n return default

Expressions

\n\n

Every AST node in SQLGlot is represented by a subclass of Expression.

\n\n

This module contains the implementation of all supported Expression types. Additionally,\nit exposes a number of helper functions, which are mainly used to programmatically build\nSQL expressions, such as sqlglot.expressions.select.

\n\n
\n"}, "sqlglot.expressions.Expression": {"fullname": "sqlglot.expressions.Expression", "modulename": "sqlglot.expressions", "qualname": "Expression", "kind": "class", "doc": "

The base class for all expressions in a syntax tree. Each Expression encapsulates any necessary\ncontext, such as its child expressions, their names (arg keys), and whether a given child expression\nis optional or not.

\n\n
Attributes:
\n\n
    \n
  • key: a unique key for each class in the Expression hierarchy. This is useful for hashing\nand representing expressions as strings.
    • \n
  • arg_types: determines what arguments (child nodes) are supported by an expression. It\nmaps arg keys to booleans that indicate whether the corresponding args are optional.
    • \n
\n\n
Example:
\n\n
\n
\n
>>> class Foo(Expression):\n...     arg_types = {"this": True, "expression": False}\n
\n
\n \n

The above definition informs us that Foo is an Expression that requires an argument called\n \"this\" and may also optionally receive an argument called \"expression\".

\n
\n\n
Arguments:
\n\n
    \n
  • args: a mapping used for retrieving the arguments of an expression, given their arg keys.
    • \n
  • parent: a reference to the parent expression (or None, in case of root expressions).
    • \n
  • arg_key: the arg key an expression is associated with, i.e. the name its parent expression\nuses to refer to it.
    • \n
  • comments: a list of comments that are associated with a given expression. This is used in\norder to preserve comments when transpiling SQL code.
    • \n
  • _type: the sqlglot.expressions.DataType type of an expression. This is inferred by the\noptimizer, in order to enable some transformations that require type information.

Example:
\n\n
\n
\n
>>> import sqlglot\n>>> sql = "SELECT x.a FROM x LEFT JOIN (SELECT DISTINCT y.b FROM y) AS y ON x.b = y.b"\n>>> expression = sqlglot.parse_one(sql)\n>>> eliminate_joins(expression).sql()\n'SELECT x.a FROM x'\n

Rewrite sqlglot AST to merge derived tables into the outer query.

\n\n

This also merges CTEs if they are selected from only once.

\n\n
Example:

\n
\n

\n
\n
\n\n

If leave_tables_isolated is True, this will not merge inner queries into outer\nqueries if it would result in multiple table selects in a single query:

\n\n
\n
\n
\n

expression = sqlglot.parse_one(\"SELECT a FROM (SELECT x.a FROM x) JOIN y\")\n merge_subqueries(expression, leave_tables_isolated=True).sql()\n 'SELECT a FROM (SELECT x.a FROM x) JOIN y'

Convert SELECT statements that contain the QUALIFY clause into subqueries, filtered equivalently.

\n\n

The idea behind this transformation can be seen in Snowflake's documentation for QUALIFY:\nhttps://docs.snowflake.com/en/sql-reference/constructs/qualify

\n\n

Some dialects don't support window functions in the WHERE clause, so we need to include them as\nprojections in the subquery, in order to refer to them in the outer filter using aliases. Also,\nif a column is referenced in the QUALIFY clause but is not selected, we need to include it too,\notherwise we won't be able to refer to it in the outer query's WHERE clause.

Creates a new trie out of a collection of keywords.

\n\n

The trie is represented as a sequence of nested dictionaries keyed by either single character\nstrings, or by 0, which is used to designate that a keyword is in the trie.

\n\n
Example:
\n\n
\n

\"SQLGlot

\n\n

SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine. It can be used to format SQL or translate between 19 different dialects like DuckDB, Presto, Spark, Snowflake, and BigQuery. It aims to read a wide variety of SQL inputs and output syntactically correct SQL in the targeted dialects.

\n\n

It is a very comprehensive generic SQL parser with a robust test suite. It is also quite performant, while being written purely in Python.

\n\n

You can easily customize the parser, analyze queries, traverse expression trees, and programmatically build SQL.

\n\n

Syntax errors are highlighted and dialect incompatibilities can warn or raise depending on configurations. However, it should be noted that SQL validation is not SQLGlot\u2019s goal, so some syntax errors may go unnoticed.

\n\n

Contributions are very welcome in SQLGlot; read the contribution guide to get started!

Versioning

\n\n

Given a version number MAJOR.MINOR.PATCH, SQLGlot uses the following versioning strategy:

\n\n
    \n
  • The PATCH version is incremented when there are backwards-compatible fixes or feature additions.
    • \n
  • The MINOR version is incremented when there are backwards-incompatible fixes or feature additions.
    • \n
  • The MAJOR version is incremented when there are significant backwards-incompatible fixes or feature additions.
    • \n

Examples

\n\n

Formatting and Transpiling

\n\n

Easily translate from one dialect to another. For example, date/time functions vary from dialects and can be hard to deal with:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT EPOCH_MS(1618088028295)", read="duckdb", write="hive")[0]\n
\n
\n\n
\n
'SELECT FROM_UNIXTIME(1618088028295 / 1000)'\n
\n
\n\n

SQLGlot can even translate custom time formats:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT STRFTIME(x, '%y-%-m-%S')", read="duckdb", write="hive")[0]\n
\n
\n\n
\n
"SELECT DATE_FORMAT(x, 'yy-M-ss')"\n
\n
\n\n

As another example, let's suppose that we want to read in a SQL query that contains a CTE and a cast to REAL, and then transpile it to Spark, which uses backticks for identifiers and FLOAT instead of REAL:

\n\n
\n
import sqlglot\n\nsql = """WITH baz AS (SELECT a, c FROM foo WHERE a = 1) SELECT f.a, b.b, baz.c, CAST("b"."a" AS REAL) d FROM foo f JOIN bar b ON f.a = b.a LEFT JOIN baz ON f.a = baz.a"""\nprint(sqlglot.transpile(sql, write="spark", identify=True, pretty=True)[0])\n
\n
\n\n
\n
WITH `baz` AS (\n  SELECT\n    `a`,\n    `c`\n  FROM `foo`\n  WHERE\n    `a` = 1\n)\nSELECT\n  `f`.`a`,\n  `b`.`b`,\n  `baz`.`c`,\n  CAST(`b`.`a` AS FLOAT) AS `d`\nFROM `foo` AS `f`\nJOIN `bar` AS `b`\n  ON `f`.`a` = `b`.`a`\nLEFT JOIN `baz`\n  ON `f`.`a` = `baz`.`a`\n
\n
\n\n

Comments are also preserved in a best-effort basis when transpiling SQL code:

\n\n
\n
sql = """\n/* multi\n   line\n   comment\n*/\nSELECT\n  tbl.cola /* comment 1 */ + tbl.colb /* comment 2 */,\n  CAST(x AS INT), # comment 3\n  y               -- comment 4\nFROM\n  bar /* comment 5 */,\n  tbl #          comment 6\n"""\n\nprint(sqlglot.transpile(sql, read='mysql', pretty=True)[0])\n
\n
\n\n
\n
/* multi\n   line\n   comment\n*/\nSELECT\n  tbl.cola /* comment 1 */ + tbl.colb /* comment 2 */,\n  CAST(x AS INT), /* comment 3 */\n  y /* comment 4 */\nFROM bar /* comment 5 */, tbl /*          comment 6 */\n
\n
\n\n

Metadata

\n\n

You can explore SQL with expression helpers to do things like find columns and tables:

\n\n
\n
from sqlglot import parse_one, exp\n\n# print all column references (a and b)\nfor column in parse_one("SELECT a, b + 1 AS c FROM d").find_all(exp.Column):\n    print(column.alias_or_name)\n\n# find all projections in select statements (a and c)\nfor select in parse_one("SELECT a, b + 1 AS c FROM d").find_all(exp.Select):\n    for projection in select.expressions:\n        print(projection.alias_or_name)\n\n# find all tables (x, y, z)\nfor table in parse_one("SELECT * FROM x JOIN y JOIN z").find_all(exp.Table):\n    print(table.name)\n
\n
\n\n

Parser Errors

\n\n

When the parser detects an error in the syntax, it raises a ParserError:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT foo( FROM bar")\n
\n
\n\n
sqlglot.errors.ParseError: Expecting ). Line 1, Col: 13.\n  select foo( FROM bar\n              ~~~~\n
\n\n

Structured syntax errors are accessible for programmatic use:

\n\n
\n
import sqlglot\ntry:\n    sqlglot.transpile("SELECT foo( FROM bar")\nexcept sqlglot.errors.ParseError as e:\n    print(e.errors)\n
\n
\n\n
\n
[{\n  'description': 'Expecting )',\n  'line': 1,\n  'col': 13,\n  'start_context': 'SELECT foo( ',\n  'highlight': 'FROM',\n  'end_context': ' bar'\n}]\n
\n
\n\n

Unsupported Errors

\n\n

Presto APPROX_DISTINCT supports the accuracy argument which is not supported in Hive:

\n\n
\n
import sqlglot\nsqlglot.transpile("SELECT APPROX_DISTINCT(a, 0.1) FROM foo", read="presto", write="hive")\n
\n
\n\n
\n
APPROX_COUNT_DISTINCT does not support accuracy\n'SELECT APPROX_COUNT_DISTINCT(a) FROM foo'\n
\n
\n\n

Build and Modify SQL

\n\n

SQLGlot supports incrementally building sql expressions:

\n\n
\n
from sqlglot import select, condition\n\nwhere = condition("x=1").and_("y=1")\nselect("*").from_("y").where(where).sql()\n
\n
\n\n
\n
'SELECT * FROM y WHERE x = 1 AND y = 1'\n
\n
\n\n

You can also modify a parsed tree:

\n\n
\n
from sqlglot import parse_one\nparse_one("SELECT x FROM y").from_("z").sql()\n
\n
\n\n
\n
'SELECT x FROM y, z'\n
\n
\n\n

There is also a way to recursively transform the parsed tree by applying a mapping function to each tree node:

\n\n
\n
from sqlglot import exp, parse_one\n\nexpression_tree = parse_one("SELECT a FROM x")\n\ndef transformer(node):\n    if isinstance(node, exp.Column) and node.name == "a":\n        return parse_one("FUN(a)")\n    return node\n\ntransformed_tree = expression_tree.transform(transformer)\ntransformed_tree.sql()\n
\n
\n\n
\n
'SELECT FUN(a) FROM x'\n
\n
\n\n

SQL Optimizer

\n\n

SQLGlot can rewrite queries into an \"optimized\" form. It performs a variety of techniques to create a new canonical AST. This AST can be used to standardize queries or provide the foundations for implementing an actual engine. For example:

\n\n
\n
import sqlglot\nfrom sqlglot.optimizer import optimize\n\nprint(\n    optimize(\n        sqlglot.parse_one("""\n            SELECT A OR (B OR (C AND D))\n            FROM x\n            WHERE Z = date '2021-01-01' + INTERVAL '1' month OR 1 = 0\n        """),\n        schema={"x": {"A": "INT", "B": "INT", "C": "INT", "D": "INT", "Z": "STRING"}}\n    ).sql(pretty=True)\n)\n
\n
\n\n
\n
SELECT\n  (\n    "x"."a" <> 0 OR "x"."b" <> 0 OR "x"."c" <> 0\n  )\n  AND (\n    "x"."a" <> 0 OR "x"."b" <> 0 OR "x"."d" <> 0\n  ) AS "_col_0"\nFROM "x" AS "x"\nWHERE\n  CAST("x"."z" AS DATE) = CAST('2021-02-01' AS DATE)\n
\n
\n\n

AST Introspection

\n\n

You can see the AST version of the sql by calling repr:

\n\n
\n
from sqlglot import parse_one\nprint(repr(parse_one("SELECT a + 1 AS z")))\n
\n
\n\n
\n
(SELECT expressions:\n  (ALIAS this:\n    (ADD this:\n      (COLUMN this:\n        (IDENTIFIER this: a, quoted: False)), expression:\n      (LITERAL this: 1, is_string: False)), alias:\n    (IDENTIFIER this: z, quoted: False)))\n
\n
\n\n

AST Diff

\n\n

SQLGlot can calculate the difference between two expressions and output changes in a form of a sequence of actions needed to transform a source expression into a target one:

\n\n
\n
from sqlglot import diff, parse_one\ndiff(parse_one("SELECT a + b, c, d"), parse_one("SELECT c, a - b, d"))\n
\n
\n\n
\n
[\n  Remove(expression=(ADD this:\n    (COLUMN this:\n      (IDENTIFIER this: a, quoted: False)), expression:\n    (COLUMN this:\n      (IDENTIFIER this: b, quoted: False)))),\n  Insert(expression=(SUB this:\n    (COLUMN this:\n      (IDENTIFIER this: a, quoted: False)), expression:\n    (COLUMN this:\n      (IDENTIFIER this: b, quoted: False)))),\n  Move(expression=(COLUMN this:\n    (IDENTIFIER this: c, quoted: False))),\n  Keep(source=(IDENTIFIER this: b, quoted: False), target=(IDENTIFIER this: b, quoted: False)),\n  ...\n]\n
\n
\n\n

\n\n

Custom Dialects

\n\n

Dialects can be added by subclassing Dialect:

\n\n
\n
from sqlglot import exp\nfrom sqlglot.dialects.dialect import Dialect\nfrom sqlglot.generator import Generator\nfrom sqlglot.tokens import Tokenizer, TokenType\n\n\nclass Custom(Dialect):\n    class Tokenizer(Tokenizer):\n        QUOTES = ["'", '"']\n        IDENTIFIERS = ["`"]\n\n        KEYWORDS = {\n            **Tokenizer.KEYWORDS,\n            "INT64": TokenType.BIGINT,\n            "FLOAT64": TokenType.DOUBLE,\n        }\n\n    class Generator(Generator):\n        TRANSFORMS = {exp.Array: lambda self, e: f"[{self.expressions(e)}]"}\n\n        TYPE_MAPPING = {\n            exp.DataType.Type.TINYINT: "INT64",\n            exp.DataType.Type.SMALLINT: "INT64",\n            exp.DataType.Type.INT: "INT64",\n            exp.DataType.Type.BIGINT: "INT64",\n            exp.DataType.Type.DECIMAL: "NUMERIC",\n            exp.DataType.Type.FLOAT: "FLOAT64",\n            exp.DataType.Type.DOUBLE: "FLOAT64",\n            exp.DataType.Type.BOOLEAN: "BOOL",\n            exp.DataType.Type.TEXT: "STRING",\n        }\n\nprint(Dialect["custom"])\n
\n
\n\n
<class '__main__.Custom'>\n
\n\n

SQL Execution

\n\n

One can even interpret SQL queries using SQLGlot, where the tables are represented as Python dictionaries. Although the engine is not very fast (it's not supposed to be) and is in a relatively early stage of development, it can be useful for unit testing and running SQL natively across Python objects. Additionally, the foundation can be easily integrated with fast compute kernels (arrow, pandas). Below is an example showcasing the execution of a SELECT expression that involves aggregations and JOINs:

\n\n
\n
from sqlglot.executor import execute\n\ntables = {\n    "sushi": [\n        {"id": 1, "price": 1.0},\n        {"id": 2, "price": 2.0},\n        {"id": 3, "price": 3.0},\n    ],\n    "order_items": [\n        {"sushi_id": 1, "order_id": 1},\n        {"sushi_id": 1, "order_id": 1},\n        {"sushi_id": 2, "order_id": 1},\n        {"sushi_id": 3, "order_id": 2},\n    ],\n    "orders": [\n        {"id": 1, "user_id": 1},\n        {"id": 2, "user_id": 2},\n    ],\n}\n\nexecute(\n    """\n    SELECT\n      o.user_id,\n      SUM(s.price) AS price\n    FROM orders o\n    JOIN order_items i\n      ON o.id = i.order_id\n    JOIN sushi s\n      ON i.sushi_id = s.id\n    GROUP BY o.user_id\n    """,\n    tables=tables\n)\n
\n
\n\n
\n
user_id price\n      1   4.0\n      2   3.0\n
\n

PySpark DataFrame SQL Generator

\n\n

This is a drop-in replacement for the PySpark DataFrame API that will generate SQL instead of executing DataFrame operations directly. This, when combined with the transpiling support in SQLGlot, allows one to write PySpark DataFrame code and execute it on other engines like DuckDB, Presto, Spark, Snowflake, and BigQuery.

\n\n

Currently many of the common operations are covered and more functionality will be added over time. Please open an issue or PR with your feedback or contribution to help influence what should be prioritized next and make sure your use case is properly supported.

\n\n

How to use

\n\n

Instructions

\n\n
    \n
  • Install SQLGlot and that is all that is required to just generate SQL. The examples show generating SQL and then executing that SQL on a specific engine and that will require that engine's client library.
    • \n
  • Find/replace all from pyspark.sql with from sqlglot.dataframe.
    • \n
  • Prior to any spark.read.table or spark.table run sqlglot.schema.add_table('<table_name>', <column_structure>).\n
      \n
    • The column structure can be defined the following ways:\n
        \n
      • Dictionary where the keys are column names and values are string of the Spark SQL type name.\n
          \n
        • Ex: {'cola': 'string', 'colb': 'int'}
          • \n
        • \n
      • PySpark DataFrame StructType similar to when using createDataFrame.\n
          \n
        • Ex: StructType([StructField('cola', StringType()), StructField('colb', IntegerType())])
          • \n
        • \n
      • A string of names and types similar to what is supported in createDataFrame.\n
          \n
        • Ex: cola: STRING, colb: INT
          • \n
        • \n
      • [Not Recommended] A list of string column names without type.\n
          \n
        • Ex: ['cola', 'colb']
          • \n
        • The lack of types may limit functionality in future releases.
          • \n
        • \n
      • \n
    • See Registering Custom Schema for information on how to skip this step if the information is stored externally.
      • \n
    • \n
  • Add .sql(pretty=True) to your final DataFrame command to return a list of sql statements to run that command.\n
      \n
    • In most cases a single SQL statement is returned. Currently the only exception is when caching DataFrames which isn't supported in other dialects.
      • \n
    • Spark is the default output dialect. See dialects for a full list of dialects.
      • \n
    • Ex: .sql(pretty=True, dialect='bigquery')
      • \n
    • \n
\n\n

Examples

\n\n
\n
import sqlglot\nfrom sqlglot.dataframe.sql.session import SparkSession\nfrom sqlglot.dataframe.sql import functions as F\n\nsqlglot.schema.add_table('employee', {\n  'employee_id': 'INT',\n  'fname': 'STRING',\n  'lname': 'STRING',\n  'age': 'INT',\n})  # Register the table structure prior to reading from the table\n\nspark = SparkSession()\n\ndf = (\n    spark\n    .table('employee')\n    .groupBy(F.col("age"))\n    .agg(F.countDistinct(F.col("employee_id")).alias("num_employees")) \n)\n\nprint(df.sql(pretty=True))  # Spark will be the dialect used by default\n
\n
\n\n
SELECT\n  `employee`.`age` AS `age`,\n  COUNT(DISTINCT `employee`.`employee_id`) AS `num_employees`\nFROM `employee` AS `employee`\nGROUP BY\n  `employee`.`age`\n
\n\n

Registering Custom Schema Class

\n\n

The step of adding sqlglot.schema.add_table can be skipped if you have the column structure stored externally like in a file or from an external metadata table. This can be done by writing a class that implements the sqlglot.schema.Schema abstract class and then assigning that class to sqlglot.schema.

\n\n
\n
import sqlglot\nfrom sqlglot.dataframe.sql.session import SparkSession\nfrom sqlglot.dataframe.sql import functions as F\nfrom sqlglot.schema import Schema\n\n\nclass ExternalSchema(Schema):\n  ...\n\nsqlglot.schema = ExternalSchema()\n\nspark = SparkSession()\n\ndf = (\n    spark\n    .table('employee')\n    .groupBy(F.col("age"))\n    .agg(F.countDistinct(F.col("employee_id")).alias("num_employees")) \n)\n\nprint(df.sql(pretty=True))\n
\n

Unsupportable Operations

\n\n

Any operation that lacks a way to represent it in SQL cannot be supported by this tool. An example of this would be rdd operations. Since the DataFrame API though is mostly modeled around SQL concepts most operations can be supported.

Functionality Difference: If you provide a value to replace a null and that type conflicts\nwith the type of the column then PySpark will just ignore your replacement.\nThis will try to cast them to be the same in some cases. So they won't always match.\nBest to not mix types so make sure replacement is the same type as the column

\n\n

Dialects

\n\n

While there is a SQL standard, most SQL engines support a variation of that standard. This makes it difficult\nto write portable SQL code. SQLGlot bridges all the different variations, called \"dialects\", with an extensible\nSQL transpilation framework.

\n\n

The base sqlglot.dialects.dialect.Dialect class implements a generic dialect that aims to be as universal as possible.

\n\n

Each SQL variation has its own Dialect subclass, extending the corresponding Tokenizer, Parser and Generator\nclasses as needed.

\n\n

Implementing a custom Dialect

\n\n

Consider the following example:

\n\n
\n
from sqlglot import exp\nfrom sqlglot.dialects.dialect import Dialect\nfrom sqlglot.generator import Generator\nfrom sqlglot.tokens import Tokenizer, TokenType\n\n\nclass Custom(Dialect):\n    class Tokenizer(Tokenizer):\n        QUOTES = ["'", '"']\n        IDENTIFIERS = ["`"]\n\n        KEYWORDS = {\n            **Tokenizer.KEYWORDS,\n            "INT64": TokenType.BIGINT,\n            "FLOAT64": TokenType.DOUBLE,\n        }\n\n    class Generator(Generator):\n        TRANSFORMS = {exp.Array: lambda self, e: f"[{self.expressions(e)}]"}\n\n        TYPE_MAPPING = {\n            exp.DataType.Type.TINYINT: "INT64",\n            exp.DataType.Type.SMALLINT: "INT64",\n            exp.DataType.Type.INT: "INT64",\n            exp.DataType.Type.BIGINT: "INT64",\n            exp.DataType.Type.DECIMAL: "NUMERIC",\n            exp.DataType.Type.FLOAT: "FLOAT64",\n            exp.DataType.Type.DOUBLE: "FLOAT64",\n            exp.DataType.Type.BOOLEAN: "BOOL",\n            exp.DataType.Type.TEXT: "STRING",\n        }\n
\n
\n\n

This is a typical example of adding a new dialect implementation in SQLGlot: we specify its identifier and string\ndelimiters, as well as what tokens it uses for its types and how they're associated with SQLGlot types. Since\nthe Expression classes are common for each dialect supported in SQLGlot, we may also need to override the generation\nlogic for some expressions; this is usually done by adding new entries to the TRANSFORMS mapping.

Semantic Diff for SQL

\n\n

by Iaroslav Zeigerman

\n\n

Motivation

\n\n

Software is constantly changing and evolving, and identifying what has changed and reviewing those changes is an integral part of the development process. SQL code is no exception to this.

\n\n

Text-based diff tools such as git diff, when applied to a code base, have certain limitations. First, they can only detect insertions and deletions, not movements or updates of individual pieces of code. Second, such tools can only detect changes between lines of text, which is too coarse for something as granular and detailed as source code. Additionally, the outcome of such a diff is dependent on the underlying code formatting, and yields different results if the formatting should change.

\n\n

Consider the following diff generated by Git:

\n\n

\"Git

\n\n

Semantically the query hasn\u2019t changed. The two arguments b and c have been swapped (moved), posing no impact on the output of the query. Yet Git replaced the whole affected expression alongside a bulk of unrelated elements.

\n\n

The alternative to text-based diffing is to compare Abstract Syntax Trees (AST) instead. The main advantage of ASTs are that they are a direct product of code parsing, which represents the underlying code structure at any desired level of granularity. Comparing ASTs may yield extremely precise diffs; changes such as code movements and updates can also be detected. Even more importantly, this approach facilitates additional use cases beyond eyeballing two versions of source code side by side.

\n\n

The use cases I had in mind for SQL when I decided to embark on this journey of semantic diffing were the following:

\n\n
    \n
  • Query similarity score. Identifying which parts the two queries have in common to automatically suggest opportunities for consolidation, creation of intermediate/staging tables, and so on.
    • \n
  • Differentiating between cosmetic / structural changes and functional ones. For example when a nested query is refactored into a common table expression (CTE), this kind of change doesn\u2019t have any functional impact on either a query or its outcome.
    • \n
  • Automatic suggestions about the need to retroactively backfill data. This is especially important for pipelines that populate very large tables for which restatement is a runtime-intensive procedure. The ability to discern between simple code movements and actual modifications can help assess the impact of a change and make suggestions accordingly.
    • \n
\n\n

The implementation discussed in this post is now a part of the SQLGlot library. You can find a complete source code in the diff.py module. The choice of SQLglot was an obvious one due to its simple but powerful API, lack of external dependencies and, more importantly, extensive list of supported SQL dialects.

\n\n

The Search for a Solution

\n\n

When it comes to any diffing tool (not just a semantic one), the primary challenge is to match as many elements of compared entities as possible. Once such a set of matching elements is available, deriving a sequence of changes becomes an easy task.

\n\n

If our elements have unique identifiers associated with them (for example, an element\u2019s ID in DOM), the matching problem is trivial. However, the SQL syntax trees that we are comparing have neither unique keys nor object identifiers that can be used for the purposes of matching. So, how do we suppose to find pairs of nodes that are related?

\n\n

To better illustrate the problem, consider comparing the following SQL expressions: SELECT a + b + c, d, e and SELECT a - b + c, e, f. Matching individual nodes from respective syntax trees can be visualized as follows:

\n\n

\"Figure\nFigure 1: Example of node matching for two SQL expression trees.

\n\n

By looking at the figure of node matching for two SQL expression trees above, we conclude that the following changes should be captured by our solution:

\n\n
    \n
  • Inserted nodes: Sub and f. These are the nodes from the target AST which do not have a matching node in the source AST.
    • \n
  • Removed nodes: Add and d. These are the nodes from the source AST which do not have a counterpart in the target AST.
    • \n
  • Remaining nodes must be identified as unchanged.
    • \n
\n\n

It should be clear at this point that if we manage to match nodes in the source tree with their counterparts in the target tree, then computing the diff becomes a trivial matter.

\n\n

Na\u00efve Brute-Force

\n\n

The na\u00efve solution would be to try all different permutations of node pair combinations, and see which set of pairs performs the best based on some type of heuristics. The runtime cost of such a solution quickly reaches the escape velocity; if both trees had only 10 nodes each, the number of such sets would approximately be 10! ^ 2 = 3.6M ^ 2 ~= 13 * 10^12. This is a very bad case of factorial complexity (to be precise, it\u2019s actually much worse - O(n! ^ 2) - but I couldn\u2019t come up with a name for it), so there is little need to explore this approach any further.

\n\n

Myers Algorithm

\n\n

After the na\u00efve approach was proven to be infeasible, the next question I asked myself was \u201chow does git diff work?\u201d. This question led me to discover the Myers diff algorithm [1]. This algorithm has been designed to compare sequences of strings. At its core, it\u2019s looking for the shortest path on a graph of possible edits that transform the first sequence into the second one, while heavily rewarding those paths that lead to longest subsequences of unchanged elements. There\u2019s a lot of material out there describing this algorithm in greater detail. I found James Coglan\u2019s series of blog posts to be the most comprehensive.

\n\n

Therefore, I had this \u201cbrilliant\u201d (actually not) idea to transform trees into sequences by traversing them in topological order, and then applying the Myers algorithm on resulting sequences while using a custom heuristics when checking the equality of two nodes. Unsurprisingly, comparing sequences of strings is quite different from comparing hierarchical tree structures, and by flattening trees into sequences, we lose a lot of relevant context. This resulted in a terrible performance of this algorithm on ASTs. It often matched completely unrelated nodes, even when the two trees were mostly the same, and produced extremely inaccurate lists of changes overall. After playing around with it a little and tweaking my equality heuristics to improve accuracy, I ultimately scrapped the whole implementation and went back to the drawing board.

\n\n

Change Distiller

\n\n

The algorithm I settled on at the end was Change Distiller, created by Fluri et al. [2], which in turn is an improvement over the core idea described by Chawathe et al. [3].

\n\n

The algorithm consists of two high-level steps:

\n\n
    \n
  1. Finding appropriate matchings between pairs of nodes that are part of compared ASTs. Identifying what is meant by \u201cappropriate\u201d matching is also a part of this step.
    2. \n
  2. Generating the so-called \u201cedit script\u201d from the matching set built in the 1st step. The edit script is a sequence of edit operations (for example, insert, remove, update, etc.) on individual tree nodes, such that when applied as transformations on the source AST, it eventually becomes the target AST. In general, the shorter the sequence, the better. The length of the edit script can be used to compare the performance of different algorithms, though this is not the only metric that matters.
    3. \n
\n\n

The rest of this section is dedicated to the Python implementation of the steps above using the AST implementation provided by the SQLGlot library.

\n\n

Building the Matching Set

\n\n

Matching Leaves

\n\n

We begin composing the matching set by matching the leaf nodes. Leaf nodes are the nodes that do not have any children nodes (such as literals, identifiers, etc.). In order to match them, we gather all the leaf nodes from the source tree and generate a cartesian product with all the leaves from the target tree, while comparing pairs created this way and assigning them a similarity score. During this stage, we also exclude pairs that don\u2019t pass basic matching criteria. Then, we pick pairs that scored the highest while making sure that each node is matched no more than once.

\n\n

Using the example provided at the beginning of the post, the process of building an initial set of candidate matchings can be seen on Figure 2.

\n\n

\"Figure\nFigure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes.

\n\n

First, let\u2019s analyze the similarity score. Then, we\u2019ll discuss matching criteria.

\n\n

The similarity score proposed by Fluri et al. [2] is a dice coefficient applied to bigrams of respective node values. A bigram is a sequence of two adjacent elements from a string computed in a sliding window fashion:

\n\n
\n
def bigram(string):\n    count = max(0, len(string) - 1)\n    return [string[i : i + 2] for i in range(count)]\n
\n
\n\n

For reasons that will become clear shortly, we actually need to compute bigram histograms rather than just sequences:

\n\n
\n
from collections import defaultdict\n\ndef bigram_histo(string):\n    count = max(0, len(string) - 1)\n    bigram_histo = defaultdict(int)\n    for i in range(count):\n        bigram_histo[string[i : i + 2]] += 1\n    return bigram_histo\n
\n
\n\n

The dice coefficient formula looks like following:

\n\n

\"Dice

\n\n

Where X is a bigram of the source node and Y is a bigram of the second one. What this essentially does is count the number of bigram elements the two nodes have in common, multiply it by 2, and then divide by the total number of elements in both bigrams. This is where bigram histograms come in handy:

\n\n
\n
def dice_coefficient(source, target):\n    source_histo = bigram_histo(source.sql())\n    target_histo = bigram_histo(target.sql())\n\n    total_grams = (\n        sum(source_histo.values()) + sum(target_histo.values())\n    )\n    if not total_grams:\n        return 1.0 if source == target else 0.0\n\n    overlap_len = 0\n    overlapping_grams = set(source_histo) & set(target_histo)\n    for g in overlapping_grams:\n        overlap_len += min(source_histo[g], target_histo[g])\n\n    return 2 * overlap_len / total_grams\n
\n
\n\n

To compute a bigram given a tree node, we first transform the node into its canonical SQL representation,so that the Literal(123) node becomes just \u201c123\u201d and the Identifier(\u201ca\u201d) node becomes just \u201ca\u201d. We also handle a scenario when strings are too short to derive bigrams. In this case, we fallback to checking the two nodes for equality.

\n\n

Now when we know how to compute the similarity score, we can take care of the matching criteria for leaf nodes. In the original paper [2], the matching criteria is formalized as follows:

\n\n

\"Matching

\n\n

The two nodes are matched if two conditions are met:

\n\n
    \n
  1. The node labels match (in our case labels are just node types).
    2. \n
  2. The similarity score for node values is greater than or equal to some threshold \u201cf\u201d. The authors of the paper recommend setting the value of \u201cf\u201d to 0.6.
    3. \n
\n\n

With building blocks in place, we can now build a matching set for leaf nodes. First, we generate a list of candidates for matching:

\n\n
\n
from heapq import heappush, heappop\n\ncandidate_matchings = []\nsource_leaves = _get_leaves(self._source)\ntarget_leaves = _get_leaves(self._target)\nfor source_leaf in source_leaves:\n    for target_leaf in target_leaves:\n        if _is_same_type(source_leaf, target_leaf):\n            similarity_score = dice_coefficient(\n                source_leaf, target_leaf\n            )\n            if similarity_score >= 0.6:\n                heappush(\n                    candidate_matchings,\n                    (\n                        -similarity_score,\n                        len(candidate_matchings),\n                        source_leaf,\n                        target_leaf,\n                    ),\n                )\n
\n
\n\n

In the implementation above, we push each matching pair onto the heap to automatically maintain the correct order based on the assigned similarity score.

\n\n

Finally, we build the initial matching set by picking leaf pairs with the highest score:

\n\n
\n
matching_set = set()\nwhile candidate_matchings:\n    _, _, source_leaf, target_leaf = heappop(candidate_matchings)\n    if (\n        source_leaf in unmatched_source_nodes\n        and target_leaf in unmatched_target_nodes\n    ):\n        matching_set.add((source_leaf, target_leaf))\n        unmatched_source_nodes.remove(source_leaf)\n        unmatched_target_nodes.remove(target_leaf)\n
\n
\n\n

To finalize the matching set, we should now proceed with matching inner nodes.

\n\n

Matching Inner Nodes

\n\n

Matching inner nodes is quite similar to matching leaf nodes, with the following two distinctions:

\n\n
    \n
  • Rather than ranking a set of possible candidates, we pick the first node pair that passes the matching criteria.
    • \n
  • The matching criteria itself has been extended to account for the number of leaf nodes the pair of inner nodes have in common.
    • \n
\n\n

\"Figure\nFigure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched.

\n\n

Let\u2019s start with the matching criteria. The criteria is formalized as follows:

\n\n

\"Matching

\n\n

Alongside already familiar similarity score and node type criteria, there is a new one in the middle: the ratio of leaf nodes that the two nodes have in common must exceed some threshold \u201ct\u201d. The recommended value for \u201ct\u201d is also 0.6. Counting the number of common leaf nodes is pretty straightforward, since we already have the complete matching set for leaves. All we need to do is count how many matching pairs do leaf nodes from the two compared inner nodes form.

\n\n

There are two additional heuristics associated with this matching criteria:

\n\n
    \n
  • Inner node similarity weighting: if the similarity score between the node values doesn\u2019t pass the threshold \u201cf\u201d but the ratio of common leaf nodes (\u201ct\u201d) is greater than or equal to 0.8, then the matching is considered successful.
    • \n
  • The threshold \u201ct\u201d is reduced to 0.4 for inner nodes with the number of leaf nodes equal to 4 or less, in order to decrease the false negative rate for small subtrees.
    • \n
\n\n

We now only have to iterate through the remaining unmatched nodes and form matching pairs based on the outlined criteria:

\n\n
\n
leaves_matching_set = matching_set.copy()\n\nfor source_node in unmatched_source_nodes.copy():\n    for target_node in unmatched_target_nodes:\n        if _is_same_type(source_node, target_node):\n            source_leaves = set(_get_leaves(source_node))\n            target_leaves = set(_get_leaves(target_node))\n\n            max_leaves_num = max(len(source_leaves), len(target_leaves))\n            if max_leaves_num:\n                common_leaves_num = sum(\n                    1 if s in source_leaves and t in target_leaves else 0\n                    for s, t in leaves_matching_set\n                )\n                leaf_similarity_score = common_leaves_num / max_leaves_num\n            else:\n                leaf_similarity_score = 0.0\n\n            adjusted_t = (\n                0.6\n                if min(len(source_leaves), len(target_leaves)) > 4\n                else 0.4\n            )\n\n            if leaf_similarity_score >= 0.8 or (\n                leaf_similarity_score >= adjusted_t\n                and dice_coefficient(source_node, target_node) >= 0.6\n            ):\n                matching_set.add((source_node, target_node))\n                unmatched_source_nodes.remove(source_node)\n                unmatched_target_nodes.remove(target_node)\n                break\n
\n
\n\n

After the matching set is formed, we can proceed with generation of the edit script, which will be the algorithm\u2019s output.

\n\n

Generating the Edit Script

\n\n

At this point, we should have the following 3 sets at our disposal:

\n\n
    \n
  • The set of matched node pairs.
    • \n
  • The set of remaining unmatched nodes from the source tree.
    • \n
  • The set of remaining unmatched nodes from the target tree.

We can derive 3 kinds of edits from the matching set: either the node\u2019s value was updated (Update), the node was moved to a different position within the tree (Move), or the node remained unchanged (Keep). Note that the Move case is not mutually exclusive with the other two. The node could have been updated or could have remained the same while at the same time its position within its parent node or the parent node itself could have changed. All unmatched nodes from the source tree are the ones that were removed (Remove), while unmatched nodes from the target tree are the ones that were inserted (Insert).

\n\n

The latter two cases are pretty straightforward to implement:

\n\n
\n
edit_script = []\n\nfor removed_node in unmatched_source_nodes:\n    edit_script.append(Remove(removed_node))\nfor inserted_node in unmatched_target_nodes:\n    edit_script.append(Insert(inserted_node))\n
\n
\n\n

Traversing the matching set requires a little more thought:

\n\n
\n
for source_node, target_node in matching_set:\n    if (\n        not isinstance(source_node, LEAF_EXPRESSION_TYPES)\n        or source_node == target_node\n    ):\n        move_edits = generate_move_edits(\n            source_node, target_node, matching_set\n        )\n        edit_script.extend(move_edits)\n        edit_script.append(Keep(source_node, target_node))\n    else:\n        edit_script.append(Update(source_node, target_node))\n
\n
\n\n

If a matching pair represents a pair of leaf nodes, we check if they are the same to decide whether an update took place. For inner node pairs, we also need to compare the positions of their respective children to detect node movements. Chawathe et al. [3] suggest applying the longest common subsequence (LCS) algorithm which, no surprise here, was described by Myers himself [1]. There is a small catch, however: instead of checking the equality of two children nodes, we need to check whether the two nodes form a pair that is a part of our matching set.

\n\n

Now with this knowledge, the implementation becomes straightforward:

\n\n
\n
def generate_move_edits(source, target, matching_set):\n    source_children = _get_child_nodes(source)\n    target_children = _get_child_nodes(target)\n\n    lcs = set(\n        _longest_common_subsequence(\n            source_children,\n            target_children,\n            lambda l, r: (l, r) in matching_set\n        )\n    )\n\n    move_edits = []\n    for node in source_children:\n        if node not in lcs and node not in unmatched_source_nodes:\n            move_edits.append(Move(node))\n\n    return move_edits\n
\n
\n\n

I left out the implementation of the LCS algorithm itself here, but there are plenty of implementation choices out there that can be easily looked up.

\n\n

Output

\n\n

The implemented algorithm produces the output that resembles the following:

\n\n
\n
>>> from sqlglot import parse_one, diff\n>>> diff(parse_one("SELECT a + b + c, d, e"), parse_one("SELECT a - b + c, e, f"))\n\nRemove(Add)\nRemove(Column(d))\nRemove(Identifier(d))\nInsert(Sub)\nInsert(Column(f))\nInsert(Identifier(f))\nKeep(Select, Select)\nKeep(Add, Add)\nKeep(Column(a), Column(a))\nKeep(Identifier(a), Identifier(a))\nKeep(Column(b), Column(b))\nKeep(Identifier(b), Identifier(b))\nKeep(Column(c), Column(c))\nKeep(Identifier(c), Identifier(c))\nKeep(Column(e), Column(e))\nKeep(Identifier(e), Identifier(e))\n
\n
\n\n

Note that the output above is abbreviated. The string representation of actual AST nodes is significantly more verbose.

\n\n

The implementation works especially well when coupled with the SQLGlot\u2019s query optimizer which can be used to produce canonical representations of compared queries:

\n\n
\n
>>> schema={"t": {"a": "INT", "b": "INT", "c": "INT", "d": "INT"}}\n>>> source = """\n... SELECT 1 + 1 + a\n... FROM t\n... WHERE b = 1 OR (c = 2 AND d = 3)\n... """\n>>> target = """\n... SELECT 2 + a\n... FROM t\n... WHERE (b = 1 OR c = 2) AND (b = 1 OR d = 3)\n... """\n>>> optimized_source = optimize(parse_one(source), schema=schema)\n>>> optimized_target = optimize(parse_one(target), schema=schema)\n>>> edit_script = diff(optimized_source, optimized_target)\n>>> sum(0 if isinstance(e, Keep) else 1 for e in edit_script)\n0\n
\n
\n\n

Optimizations

\n\n

The worst case runtime complexity of this algorithm is not exactly stellar: O(n^2 * log n^2). This is because of the leaf matching process, which involves ranking a cartesian product between all leaf nodes of compared trees. Unsurprisingly, the algorithm takes a considerable time to finish for bigger queries.

\n\n

There are still a few basic things we can do in our implementation to help improve performance:

\n\n
    \n
  • Refer to individual node objects using their identifiers (Python\u2019s id()) instead of direct references in sets. This helps avoid costly recursive hash calculations and equality checks.
    • \n
  • Cache bigram histograms to avoid computing them more than once for the same node.
    • \n
  • Compute the canonical SQL string representation for each tree once while caching string representations of all inner nodes. This prevents redundant tree traversals when bigrams are computed.
    • \n
\n\n

At the time of writing only the first two optimizations have been implemented, so there is an opportunity to contribute for anyone who\u2019s interested.

\n\n

Alternative Solutions

\n\n

This section is dedicated to solutions that I\u2019ve investigated, but haven\u2019t tried.

\n\n

First, this section wouldn\u2019t be complete without Tristan Hume\u2019s blog post. Tristan\u2019s solution has a lot in common with the Myers algorithm plus heuristics that is much more clever than what I came up with. The implementation relies on a combination of dynamic programming and A* search algorithm to explore the space of possible matchings and pick the best ones. It seemed to have worked well for Tistan\u2019s specific use case, but after my negative experience with the Myers algorithm, I decided to try something different.

\n\n

Another notable approach is the Gumtree algorithm by Falleri et al. [4]. I discovered this paper after I\u2019d already implemented the algorithm that is the main focus of this post. In sections 5.2 and 5.3 of their paper, the authors compare the two algorithms side by side and claim that Gumtree is significantly better in terms of both runtime performance and accuracy when evaluated on 12 792 pairs of Java source files. This doesn\u2019t surprise me, as the algorithm takes the height of subtrees into account. In my tests, I definitely saw scenarios in which this context would have helped. On top of that, the authors promise O(n^2) runtime complexity in the worst case which, given the Change Distiller's O(n^2 * log n^2), looks particularly tempting. I hope to try this algorithm out at some point, and there is a good chance you see me writing about it in my future posts.

\n\n

Conclusion

\n\n

The Change Distiller algorithm yielded quite satisfactory results in most of my tests. The scenarios in which it fell short mostly concerned identical (or very similar) subtrees located in different parts of the AST. In those cases, node mismatches were frequent and, as a result, edit scripts were somewhat suboptimal.

\n\n

Additionally, the runtime performance of the algorithm leaves a lot to be desired. On trees with 1000 leaf nodes each, the algorithm takes a little under 2 seconds to complete. My implementation still has room for improvement, but this should give you a rough idea of what to expect. It appears that the Gumtree algorithm [4] can help address both of these points. I hope to find bandwidth to work on it soon and then compare the two algorithms side-by-side to find out which one performs better on SQL specifically. In the meantime, Change Distiller definitely gets the job done, and I can now proceed with applying it to some of the use cases I mentioned at the beginning of this post.

\n\n

I\u2019m also curious to learn whether other folks in the industry faced a similar problem, and how they approached it. If you did something similar, I\u2019m interested to hear about your experience.

Writing a Python SQL engine from scratch

\n\n

Toby Mao

\n\n

Introduction

\n\n

When I first started writing SQLGlot in early 2021, my goal was just to translate SQL queries from SparkSQL to Presto and vice versa. However, over the last year and a half, I've ended up with a full-fledged SQL engine. SQLGlot can now parse and transpile between 18 SQL dialects and can execute all 24 TPC-H SQL queries. The parser and engine are all written from scratch using Python.

\n\n

This post will cover why I went through the effort of creating a Python SQL engine and how a simple query goes from a string to actually transforming data. The following steps are briefly summarized:

\n\n\n\n

Why?

\n\n

I started working on SQLGlot because of my work on the experimentation and metrics platform at Netflix, where I built tools that allowed data scientists to define and compute SQL-based metrics. Netflix relied on multiple engines to query data (Spark, Presto, and Druid), so my team built the metrics platform around PyPika, a Python SQL query builder. This way, definitions could be reused across multiple engines. However, it became quickly apparent that writing python code to programmatically generate SQL was challenging for data scientists, especially those with academic backgrounds, since they were mostly familiar with R and SQL. At the time, the only Python SQL parser was sqlparse, which is not actually a parser but a tokenizer, so having users write raw SQL into the platform wasn't really an option. Some time later, I randomly stumbled across Crafting Interpreters and realized that I could use it as a guide towards creating my own SQL parser/transpiler.

\n\n

Why did I do this? Isn't a Python SQL engine going to be extremely slow?

\n\n

The main reason why I ended up building a SQL engine was...just for entertainment. It's been fun learning about all the things required to actually run a SQL query, and seeing it actually work is extremely rewarding. Before SQLGlot, I had zero experience with lexers, parsers, or compilers.

\n\n

In terms of practical use cases, I planned to use the Python SQL engine for unit testing SQL pipelines. Big data pipelines are tough to test because many of the engines are not open source and cannot be run locally. With SQLGlot, you can take a SQL query targeting a warehouse such as Snowflake and seamlessly run it in CI on mock Python data. It's easy to mock data and create arbitrary UDFs because everything is just Python. Although the implementation is slow and unsuitable for large amounts of data (> 1 million rows), there's very little overhead/startup and you can run queries on test data in a couple of milliseconds.

\n\n

Finally, the components that have been built to support execution can be used as a foundation for a faster engine. I'm inspired by what Apache Calcite has done for the JVM world. Even though Python is commonly used for data, there hasn't been a Calcite for Python. So, you could say that SQLGlot aims to be that framework. For example, it wouldn't take much work to replace the Python execution engine with numpy/pandas/arrow to become a respectably-performing query engine. The implementation would be able to leverage the parser, optimizer, and logical planner, only needing to implement physical execution. There is a lot of work in the Python ecosystem around high performance vectorized computation, which I think could benefit from a pure Python-based AST/plan. Parsing and planning doesn't have to be fast when the bottleneck of running queries is processing terabytes of data. So, having a Python-based ecosystem around SQL is beneficial given the ease of development in Python, despite not having bare metal performance.

\n\n

Parts of SQLGlot's toolkit are being used today by the following:

\n\n
    \n
  • Ibis: A Python library that provides a lightweight, universal interface for data wrangling.\n
      \n
    • Uses the Python SQL expression builder and leverages the optimizer/planner to convert SQL into dataframe operations.
      • \n
    • \n
  • mysql-mimic: Pure-Python implementation of the MySQL server wire protocol\n
      \n
    • Parses / transforms SQL and executes INFORMATION_SCHEMA queries.
      • \n
    • \n
  • Quokka: Push-based vectorized query engine\n
      \n
    • Parse and optimizes SQL.
      • \n
    • \n
  • Splink: Fast, accurate and scalable probabilistic data linkage using your choice of SQL backend.\n
      \n
    • Transpiles queries.
      • \n
    • \n
\n\n

How?

\n\n

There are many steps involved with actually running a simple query like:

\n\n
\n
SELECT\n  bar.a,\n  b + 1 AS b\nFROM bar\nJOIN baz\n  ON bar.a = baz.a\nWHERE bar.a > 1\n
\n
\n\n

In this post, I'll walk through all the steps SQLGlot takes to run this query over Python objects.

\n\n

Tokenizing

\n\n

The first step is to convert the sql string into a list of tokens. SQLGlot's tokenizer is quite simple and can be found here. In a while loop, it checks each character and either appends the character to the current token, or makes a new token.

\n\n

Running the SQLGlot tokenizer shows the output.

\n\n

\"Tokenizer

\n\n

Each keyword has been converted to a SQLGlot Token object. Each token has some metadata associated with it, like line/column information for error messages. Comments are also a part of the token, so that comments can be preserved.

\n\n

Parsing

\n\n

Once a SQL statement is tokenized, we don't need to worry about white space and other formatting, so it's easier to work with. We can now convert the list of tokens into an AST. The SQLGlot parser is a handwritten recursive descent parser.

\n\n

Similar to the tokenizer, it consumes the tokens sequentially, but it instead uses a recursive algorithm. The tokens are converted into a single AST node that presents the SQL query. The SQLGlot parser was designed to support various dialects, so it contains many options for overriding parsing functionality.

\n\n

\"Parser

\n\n

The AST is a generic representation of a given SQL query. Each dialect can override or implement its own generator, which can convert an AST object into syntatically-correct SQL.

\n\n

Optimizing

\n\n

Once we have our AST, we can transform it into an equivalent query that produces the same results more efficiently. When optimizing queries, most engines first convert the AST into a logical plan and then optimize the plan. However, I chose to optimize the AST directly for the following reasons:

\n\n
    \n

  1. It's easier to debug and validate the optimizations when the input and output are both SQL.

    2. \n

  2. Rules can be applied a la carte to transform SQL into a more desirable form.

    3. \n

  3. I wanted a way to generate 'canonical sql'. Having a canonical representation of SQL is useful for understanding if two queries are semantically equivalent (e.g. SELECT 1 + 1 and SELECT 2).

    4. \n
\n\n

I've yet to find another engine that takes this approach, but I'm quite happy with this decision. The optimizer currently does not perform any \"physical optimizations\" such as join reordering. Those are left to the execution layer, as additional statistics and information could become relevant.

\n\n

\"Optimizer

\n\n

The optimizer currently has 17 rules. Each of these rules is applied, transforming the AST in place. The combination of these rules creates \"canonical\" sql that can then be more easily converted into a logical plan and executed.

\n\n

Some example rules are:

\n\n

qualify_tables and qualify_columns

\n\n
    \n
  • Adds all db/catalog qualifiers to tables and forces an alias.
    • \n
  • Ensure each column is unambiguous and expand stars.
    • \n
\n\n
\n
SELECT * FROM x;\n\nSELECT "db"."x" AS "x";\n
\n
\n\n

annotate_types

\n\n

Infer all types throughout the AST given schema information and function type definitions.

\n\n

Planning

\n\n

After the SQL AST has been \"optimized\", it's much easier to convert into a logical plan. The AST is traversed and converted into a DAG consisting of one of five steps. The different steps are:

\n\n

Scan

\n\n

Selects columns from a table, applies projections, and finally filters the table.

\n\n

Sort

\n\n

Sorts a table for order by expressions.

\n\n

Set

\n\n

Applies the operators union/union all/except/intersect.

\n\n

Aggregate

\n\n

Applies an aggregation/group by.

\n\n

Join

\n\n

Joins multiple tables together.

\n\n

\"Planner

\n\n

The logical plan is quite simple and contains the information required to convert it into a physical plan (execution).

\n\n

Executing

\n\n

Finally, we can actually execute the SQL query. The Python engine is not fast, but it's very small (~400 LOC)! It iterates the DAG with a queue and runs each step, passing each intermediary table to the next step.

\n\n

In order to keep things simple, it evaluates expressions with eval. Because SQLGlot was built primarily to be a transpiler, it was simple to create a \"Python SQL\" dialect. So a SQL expression x + 1 can just be converted into scope['x'] + 1.

\n\n

\"Executor

\n\n

What's next

\n\n

SQLGlot's main focus will always be on parsing/transpiling, but I plan to continue development on the execution engine. I'd like to pass TPC-DS. If someone doesn't beat me to it, I may even take a stab at writing a Pandas/Arrow execution engine.

\n\n

I'm hoping that over time, SQLGlot will spark the Python SQL ecosystem just like Calcite has for Java.

\n\n

Special thanks

\n\n

SQLGlot would not be what it is without it's core contributors. In particular, the execution engine would not exist without Barak Alon and George Sittas.

Abstract base class for generic types.

\n\n

A generic type is typically declared by inheriting from\nthis class parameterized with one or more type variables.\nFor example, a generic mapping type might be defined as::

\n\n

class Mapping(Generic[KT, VT]):\n def __getitem__(self, key: KT) -> VT:\n ...\n # Etc.

\n\n

This class can then be used as follows::

\n\n

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT:\n try:\n return mapping[key]\n except KeyError:\n return default

Expressions

\n\n

Every AST node in SQLGlot is represented by a subclass of Expression.

\n\n

This module contains the implementation of all supported Expression types. Additionally,\nit exposes a number of helper functions, which are mainly used to programmatically build\nSQL expressions, such as sqlglot.expressions.select.

\n\n
\n"}, "sqlglot.expressions.Expression": {"fullname": "sqlglot.expressions.Expression", "modulename": "sqlglot.expressions", "qualname": "Expression", "kind": "class", "doc": "

The base class for all expressions in a syntax tree. Each Expression encapsulates any necessary\ncontext, such as its child expressions, their names (arg keys), and whether a given child expression\nis optional or not.

\n\n
Attributes:
\n\n
    \n
  • key: a unique key for each class in the Expression hierarchy. This is useful for hashing\nand representing expressions as strings.
    • \n
  • arg_types: determines what arguments (child nodes) are supported by an expression. It\nmaps arg keys to booleans that indicate whether the corresponding args are optional.
    • \n
  • parent: a reference to the parent expression (or None, in case of root expressions).
    • \n
  • arg_key: the arg key an expression is associated with, i.e. the name its parent expression\nuses to refer to it.
    • \n
  • comments: a list of comments that are associated with a given expression. This is used in\norder to preserve comments when transpiling SQL code.
    • \n
  • _type: the sqlglot.expressions.DataType type of an expression. This is inferred by the\noptimizer, in order to enable some transformations that require type information.

Convert all unquoted identifiers to lower case.

\n\n

Assuming the schema is all lower case, this essentially makes identifiers case-insensitive.

Rewrite sqlglot AST to merge derived tables into the outer query.

\n\n

This also merges CTEs if they are selected from only once.

\n\n
Example:
\n\n
\n
\n
>>> import sqlglot\n>>> expression = sqlglot.parse_one("SELECT a FROM (SELECT x.a FROM x) CROSS JOIN y")\n>>> merge_subqueries(expression).sql()\n'SELECT x.a FROM x CROSS JOIN y'\n
\n
\n
\n\n

If leave_tables_isolated is True, this will not merge inner queries into outer\nqueries if it would result in multiple table selects in a single query:

\n\n
\n
\n
\n

expression = sqlglot.parse_one(\"SELECT a FROM (SELECT x.a FROM x) CROSS JOIN y\")\n merge_subqueries(expression, leave_tables_isolated=True).sql()\n 'SELECT a FROM (SELECT x.a FROM x) CROSS JOIN y'

Abstract base class for generic types.

\n\n

A generic type is typically declared by inheriting from\nthis class parameterized with one or more type variables.\nFor example, a generic mapping type might be defined as::

\n\n

class Mapping(Generic[KT, VT]):\n def __getitem__(self, key: KT) -> VT:\n ...\n # Etc.

\n\n

This class can then be used as follows::

The idea behind this transformation can be seen in Snowflake's documentation for QUALIFY:\nhttps://docs.snowflake.com/en/sql-reference/constructs/qualify

\n\n

Some dialects don't support window functions in the WHERE clause, so we need to include them as\nprojections in the subquery, in order to refer to them in the outer filter using aliases. Also,\nif a column is referenced in the QUALIFY clause but is not selected, we need to include it too,\notherwise we won't be able to refer to it in the outer query's WHERE clause.

        Versioning

        + +

        Given a version number MAJOR.MINOR.PATCH, SQLGlot uses the following versioning strategy:

        + +
          +
        • The PATCH version is incremented when there are backwards-compatible fixes or feature additions.
          • +
        • The MINOR version is incremented when there are backwards-incompatible fixes or feature additions.
          • +
        • The MAJOR version is incremented when there are significant backwards-incompatible fixes or feature additions.
          • +
