It can be used to format SQL or translate between <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/dialects/__init__.py\">19 different dialects</a> like <a href=\"https://duckdb.org/\">DuckDB</a>, <a href=\"https://prestodb.io/\">Presto</a>, <a href=\"https://spark.apache.org/\">Spark</a>, <a href=\"https://www.snowflake.com/en/\">Snowflake</a>, and <a href=\"https://cloud.google.com/bigquery/\">BigQuery</a>. It aims to read a wide variety of SQL inputs and output syntactically correct SQL in the targeted dialects.</p>\n\n<p>It is a very comprehensive generic SQL parser with a robust <a href=\"https://github.com/tobymao/sqlglot/blob/main/tests/\">test suite</a>. It is also quite <a href=\"#benchmarks\">performant</a>, while being written purely in Python.</p>\n\n<p>You can easily <a href=\"#custom-dialects\">customize</a> the parser, <a href=\"#metadata\">analyze</a> queries, traverse expression trees, and programmatically <a href=\"#build-and-modify-sql\">build</a> SQL.</p>\n\n<p>Syntax <a href=\"#parser-errors\">errors</a> 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.</p>\n\n<p>Contributions are very welcome in SQLGlot; read the <a href=\"https://github.com/tobymao/sqlglot/blob/main/CONTRIBUTING.md\">contribution guide</a> to get started!</p>\n\n<h2 id=\"table-of-contents\">Table of Contents</h2>\n\n<ul>\n<li><a href=\"#install\">Install</a></li>\n<li><a href=\"#get-in-touch\">Get in Touch</a></li>\n<li><a href=\"#examples\">Examples</a>\n<ul>\n<li><a href=\"#formatting-and-transpiling\">Formatting and Transpiling</a></li>\n<li><a href=\"#metadata\">Metadata</a></li>\n<li><a href=\"#parser-errors\">Parser Errors</a></li>\n<li><a href=\"#unsupported-errors\">Unsupported Errors</a></li>\n<li><a href=\"#build-and-modify-sql\">Build and Modify SQL</a></li>\n<li><a href=\"#sql-optimizer\">SQL Optimizer</a></li>\n<li><a href=\"#ast-introspection\">AST Introspection</a></li>\n<li><a href=\"#ast-diff\">AST Diff</a></li>\n<li><a href=\"#custom-dialects\">Custom Dialects</a></li>\n<li><a href=\"#sql-execution\">SQL Execution</a></li>\n</ul></li>\n<li><a href=\"#used-by\">Used By</a></li>\n<li><a href=\"#documentation\">Documentation</a></li>\n<li><a href=\"#run-tests-and-lint\">Run Tests and Lint</a></li>\n<li><a href=\"#benchmarks\">Benchmarks</a></li>\n<li><a href=\"#optional-dependencies\">Optional Dependencies</a></li>\n</ul>\n\n<h2 id=\"install\">Install</h2>\n\n<p>From PyPI:</p>\n\n<pre><code>pip3 install sqlglot\n</code></pre>\n\n<p>Or with a local checkout:</p>\n\n<pre><code>make install\n</code></pre>\n\n<p>Requirements for development (optional):</p>\n\n<pre><code>make install-dev\n</code></pre>\n\n<h2 id=\"get-in-touch\">Get in Touch</h2>\n\n<p>We'd love to hear from you.

Execution</h3>\n\n<p>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:</p>\n\n<div class=\"pdoc-code codehilite\">\n<pre><span></span><code><span

SQL code is no exception to this.</p>\n\n<p>Text-based diff tools such as <code>git diff</code>, 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.</p>\n\n<p>Consider the following diff generated by Git:</p>\n\n<p><img src=\"sql_diff_images/git_diff_output.png\" alt=\"Git diff output\" /></p>\n\n<p>Semantically the query hasn\u2019t changed. The two arguments <code>b</code> and <code>c</code> 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.</p>\n\n<p>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.</p>\n\n<p>The use cases I had in mind for SQL when I decided to embark on this journey of semantic diffing were the following:</p>\n\n<ul>\n<li><strong>Query similarity score.</strong> Identifying which parts the two queries have in common to automatically suggest opportunities for consolidation, creation of intermediate/staging tables, and so on.</li>\n<li><strong>Differentiating between cosmetic / structural changes and functional ones.</strong> 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.</li>\n<li><strong>Automatic suggestions about the need to retroactively backfill data.</strong> 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.</li>\n</ul>\n\n<p>The implementation discussed in this post is now a part of the <a href=\"https://github.com/tobymao/sqlglot/\">SQLGlot</a> library. You can find a complete source code in the <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/diff.py\">diff.py</a> 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.</p>\n\n<h2 id=\"the-search-for-a-solution\">The Search for a Solution</h2>\n\n<p>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.</p>\n\n<p>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?</p>\n\n<p>To better illustrate the problem, consider comparing the following SQL expressions: <code>SELECT a + b + c, d, e</code> and <code>SELECT a - b + c, e, f</code>. Matching individual nodes from respective syntax trees can be visualized as follows:</p>\n\n<p><img src=\"sql_diff_images/figure_1.png\" alt=\"Figure 1: Example of node matching for two SQL expression trees\" />\n<em>Figure 1: Example of node matching for two SQL expression trees.</em></p>\n\n<p>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:</p>\n\n<ul>\n<li>Inserted nodes: <code>Sub</code> and <code>f</code>. These are the nodes from the target AST which do not have a matching node in the source AST.</li>\n<li>Removed nodes: <code>Add</code> and <code>d</code>. These are the nodes from the source AST which do not have a counterpart in the target AST.</li>\n<li>Remaining nodes must be identified as unchanged.</li>\n</ul>\n\n<p>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.</p>\n\n<h3 id=\"naive-brute-force\">Na\u00efve Brute-Force</h3>\n\n<p>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.</p>\n\n<h3 id=\"myers-algorithm\">Myers Algorithm</h3>\n\n<p>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 <a href=\"https://blog.jcoglan.com/2017/02/12/the-myers-diff-algorithm-part-1/\">blog posts</a> to be the most comprehensive.</p>\n\n<p>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.</p>\n\n<h2 id=\"change-distiller\">Change Distiller</h2>\n\n<p>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].</p>\n\n<p>The algorithm consists of two high-level steps:</p>\n\n<ol>\n<li><strong>Finding appropriate matchings between pairs of nodes that are part of compared ASTs.</strong> Identifying what is meant by \u201cappropriate\u201d matching is also a part of this step.</li>\n<li><strong>Generating the so-called \u201cedit script\u201d from the matching set built in the 1st step.</strong> 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.</li>\n</ol>\n\n<p>The rest of this section is dedicated to the Python implementation of the steps above using the AST implementation provided by the SQLGlot library.</p>\n\n<h3 id=\"building-the-matching-set\">Building the Matching Set</h3>\n\n<h4 id=\"matching-leaves\">Matching Leaves</h4>\n\n<p>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.</p>\n\n<p>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.</p>\n\n<p><img src=\"sql_diff_images/figure_2.gif\" alt=\"Figure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes.\" />\n<em>Figure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes.</em></p>\n\n<p>First, let\u2019s analyze the similarity score.

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.</p>\n\n<p>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:</p>\n\n<p><img src=\"sql_diff_images/matching_criteria_1.png\" alt=\"Matching criteria for leaf nodes\" /></p>\n\n<p>The two nodes are matched if two conditions are met:</p>\n\n<ol>\n<li>The node labels match (in our case labels are just node types).</li>\n<li>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.</li>\n</ol>\n\n<p>With building blocks in place, we can now build a matching set for leaf nodes.

Nodes</h4>\n\n<p>Matching inner nodes is quite similar to matching leaf nodes, with the following two distinctions:</p>\n\n<ul>\n<li>Rather than ranking a set of possible candidates, we pick the first node pair that passes the matching criteria.</li>\n<li>The matching criteria itself has been extended to account for the number of leaf nodes the pair of inner nodes have in common.</li>\n</ul>\n\n<p><img src=\"sql_diff_images/figure_3.gif\" alt=\"Figure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched.\" />\n<em>Figure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched.</em></p>\n\n<p>Let\u2019s start with the matching criteria. The criteria is formalized as follows:</p>\n\n<p><img src=\"sql_diff_images/matching_criteria_2.png\" alt=\"Matching criteria for inner nodes\" /></p>\n\n<p>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.</p>\n\n<p>There are two additional heuristics associated with this matching criteria:</p>\n\n<ul>\n<li>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.</li>\n<li>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.</li>\n</ul>\n\n<p>We now only have to iterate through the remaining unmatched nodes and form matching pairs based on the outlined criteria:</p>\n\n<div class=\"pdoc-code codehilite\">\n<pre><span></span><code><span class=\"n\">leaves_matching_set</span> <span class=\"o\">=</span> <span

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.</p>\n\n<p>There are still a few basic things we can do in our implementation to help improve performance:</p>\n\n<ul>\n<li>Refer to individual node objects using their identifiers (Python\u2019s <a href=\"https://docs.python.org/3/library/functions.html#id\">id()</a>) instead of direct references in sets. This helps avoid costly recursive hash calculations and equality checks.</li>\n<li>Cache bigram histograms to avoid computing them more than once for the same node.</li>\n<li>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.</li>\n</ul>\n\n<p>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.</p>\n\n<h2 id=\"alternative-solutions\">Alternative Solutions</h2>\n\n<p>This section is dedicated to solutions that I\u2019ve investigated, but haven\u2019t tried.</p>\n\n<p>First, this section wouldn\u2019t be complete without Tristan Hume\u2019s <a href=\"https://thume.ca/2017/06/17/tree-diffing/\">blog post</a>. 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 <a href=\"https://en.wikipedia.org/wiki/Dynamic_programming\">dynamic programming</a> and <a href=\"https://en.wikipedia.org/wiki/A*_search_algorithm\">A* search algorithm</a> 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.</p>\n\n<p>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.</p>\n\n<h2 id=\"conclusion\">Conclusion</h2>\n\n<p>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.</p>\n\n<p>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.</p>\n\n<p>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.</p>\n\n<h2 id=\"references\">References</h2>\n\n<p>[1] Eugene W.

id=\"introduction\">Introduction</h2>\n\n<p>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 <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/dialects/__init__.py\">18 SQL dialects</a> and can execute all 24 <a href=\"https://www.tpc.org/tpch/\">TPC-H</a> SQL queries. The parser and engine are all written from scratch using Python.</p>\n\n<p>This post will cover <a href=\"#why\">why</a> I went through the effort of creating a Python SQL engine and <a href=\"#how\">how</a> a simple query goes from a string to actually transforming data. The following steps are briefly summarized:</p>\n\n<ul>\n<li><a href=\"#tokenizing\">Tokenizing</a></li>\n<li><a href=\"#parsing\">Parsing</a></li>\n<li><a href=\"#optimizing\">Optimizing</a></li>\n<li><a href=\"#planning\">Planning</a></li>\n<li><a href=\"#executing\">Executing</a></li>\n</ul>\n\n<h2 id=\"why\">Why?</h2>\n\n<p>I started working on SQLGlot because of my work on the <a href=\"https://netflixtechblog.com/reimagining-experimentation-analysis-at-netflix-71356393af21\">experimentation and metrics platform</a> 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 <a href=\"https://github.com/kayak/pypika\">PyPika</a>, 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 <a href=\"[https://github.com/andialbrecht/sqlparse\">sqlparse</a>, 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 <a href=\"https://craftinginterpreters.com/\">Crafting Interpreters</a> and realized that I could use it as a guide towards creating my own SQL parser/transpiler.</p>\n\n<p>Why did I do this? Isn't a Python SQL engine going to be extremely slow?</p>\n\n<p>The main reason why I ended up building a SQL engine was...just for <strong>entertainment</strong>. 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.</p>\n\n<p>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 <a href=\"https://www.snowflake.com/en/\">Snowflake</a> and seamlessly run it in CI on mock Python data. It's easy to mock data and create arbitrary <a href=\"https://en.wikipedia.org/wiki/User-defined_function\">UDFs</a> because everything is just Python. Although the implementation is slow and unsuitable for large amounts of data (&gt; 1 million rows), there's very little overhead/startup and you can run queries on test data in a couple of milliseconds.</p>\n\n<p>Finally, the components that have been built to support execution can be used as a <strong>foundation</strong> for a faster engine. I'm inspired by what <a href=\"https://github.com/apache/calcite\">Apache Calcite</a> 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 <a href=\"https://en.wikipedia.org/wiki/Abstract_syntax_tree\">AST</a>/<a href=\"https://en.wikipedia.org/wiki/Query_plan\">plan</a>. 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.</p>\n\n<p>Parts of SQLGlot's toolkit are being used today by the following:</p>\n\n<ul>\n<li><a href=\"https://github.com/ibis-project/ibis\">Ibis</a>: A Python library that provides a lightweight, universal interface for data wrangling.\n<ul>\n<li>Uses the Python SQL expression builder and leverages the optimizer/planner to convert SQL into dataframe operations.</li>\n</ul></li>\n<li><a href=\"https://github.com/kelsin/mysql-mimic\">mysql-mimic</a>: Pure-Python implementation of the MySQL server wire protocol\n<ul>\n<li>Parses / transforms SQL and executes INFORMATION_SCHEMA queries.</li>\n</ul></li>\n<li><a href=\"https://github.com/marsupialtail/quokka\">Quokka</a>: Push-based vectorized query engine\n<ul>\n<li>Parse and optimizes SQL.</li>\n</ul></li>\n<li><a href=\"https://github.com/moj-analytical-services/splink\">Splink</a>: Fast, accurate and scalable probabilistic data linkage using your choice of SQL backend.\n<ul>\n<li>Transpiles queries.</li>\n</ul></li>\n</ul>\n\n<h2 id=\"how\">How?</h2>\n\n<p>There are many steps involved with actually running a simple query like:</p>\n\n<div class=\"pdoc-code codehilite\">\n<pre><span></span><code><span class=\"k\">SELECT</span>\n<span class=\"w\"> </span><span class=\"n\">bar</span><span class=\"p\">.</span><span class=\"n\">a</span><span class=\"p\">,</span>\n<span class=\"w\"> </span><span class=\"n\">b</span><span class=\"w\"> </span><span class=\"o\">+</span><span class=\"w\"> </span><span class=\"mi\">1</span><span class=\"w\"> </span><span class=\"k\">AS</span><span class=\"w\"> </span><span class=\"n\">b</span>\n<span class=\"k\">FROM</span><span class=\"w\"> </span><span class=\"n\">bar</span>\n<span class=\"k\">JOIN</span><span class=\"w\"> </span><span class=\"n\">baz</span>\n<span class=\"w\"> </span><span class=\"k\">ON</span><span class=\"w\"> </span><span class=\"n\">bar</span><span class=\"p\">.</span><span class=\"n\">a</span><span class=\"w\"> </span><span class=\"o\">=</span><span class=\"w\"> </span><span class=\"n\">baz</span><span class=\"p\">.</span><span class=\"n\">a</span>\n<span class=\"k\">WHERE</span><span class=\"w\"> </span><span class=\"n\">bar</span><span class=\"p\">.</span><span class=\"n\">a</span><span class=\"w\"> </span><span class=\"o\">&gt;</span><span class=\"w\"> </span><span class=\"mi\">1</span>\n</code></pre>\n</div>\n\n<p>In this post, I'll walk through all the steps SQLGlot takes to run this query over Python objects.</p>\n\n<h2 id=\"tokenizing\">Tokenizing</h2>\n\n<p>The first step is to convert the sql string into a list of tokens. SQLGlot's tokenizer is quite simple and can be found <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/tokens.py\">here</a>. In a while loop, it checks each character and either appends the character to the current token, or makes a new token.</p>\n\n<p>Running the SQLGlot tokenizer shows the output.</p>\n\n<p><img src=\"python_sql_engine_images/tokenizer.png\" alt=\"Tokenizer Output\" /></p>\n\n<p>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.</p>\n\n<h2 id=\"parsing\">Parsing</h2>\n\n<p>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 <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/parser.py\">parser</a> is a handwritten <a href=\"https://en.wikipedia.org/wiki/Recursive_descent_parser\">recursive descent</a> parser.</p>\n\n<p>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.</p>\n\n<p><img src=\"python_sql_engine_images/parser.png\" alt=\"Parser Output\" /></p>\n\n<p>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.</p>\n\n<h2 id=\"optimizing\">Optimizing</h2>\n\n<p>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 <strong>optimize the AST directly</strong> for the following reasons:</p>\n\n<ol>\n<li><p>It's easier to debug and <a href=\"https://github.com/tobymao/sqlglot/blob/main/tests/fixtures/optimizer\">validate</a> the optimizations when the input and output are both SQL.</p></li>\n<li><p>Rules can be applied a la carte to transform SQL into a more desirable form.</p></li>\n<li><p>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. <code>SELECT 1 + 1</code> and <code>SELECT 2</code>).</p></li>\n</ol>\n\n<p>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.</p>\n\n<p><img src=\"python_sql_engine_images/optimizer.png\" alt=\"Optimizer Output\" /></p>\n\n<p>The optimizer currently has <a href=\"https://github.com/tobymao/sqlglot/tree/main/sqlglot/optimizer\">17 rules</a>. 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.</p>\n\n<p>Some example rules are:</p>\n\n<h3 id=\"qualify_tables-and-qualify_columns\">qualify_tables and qualify_columns</h3>\n\n<ul>\n<li>Adds all db/catalog qualifiers to tables and forces an alias.</li>\n<li>Ensure each column is unambiguous and expand stars.</li>\n</ul>\n\n<div class=\"pdoc-code codehilite\">\n<pre><span></span><code><span class=\"k\">SELECT</span><span class=\"w\"> </span><span class=\"o\">*</span><span class=\"w\"> </span><span class=\"k\">FROM</span><span class=\"w\"> </span><span class=\"n\">x</span><span class=\"p\">;</span>\n\n<span class=\"k\">SELECT</span><span class=\"w\"> </span><span class=\"ss\">&quot;db&quot;</span><span class=\"p\">.</span><span class=\"ss\">&quot;x&quot;</span><span class=\"w\"> </span><span class=\"k\">AS</span><span class=\"w\"> </span><span class=\"ss\">&quot;x&quot;</span><span class=\"p\">;</span>\n</code></pre>\n</div>\n\n<h3 id=\"simplify\">simplify</h3>\n\n<p>Boolean and math simplification.

href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/planner.py\">convert into a logical plan</a>. The AST is traversed and converted into a <a href=\"https://en.wikipedia.org/wiki/Directed_acyclic_graph\">DAG</a> consisting of one of five steps. The different steps are:</p>\n\n<h3 id=\"scan\">Scan</h3>\n\n<p>Selects columns from a table, applies projections, and finally filters the table.</p>\n\n<h3 id=\"sort\">Sort</h3>\n\n<p>Sorts a table for order by expressions.</p>\n\n<h3 id=\"set\">Set</h3>\n\n<p>Applies the operators union/union all/except/intersect.</p>\n\n<h3 id=\"aggregate\">Aggregate</h3>\n\n<p>Applies an aggregation/group by.</p>\n\n<h3 id=\"join\">Join</h3>\n\n<p>Joins multiple tables together.</p>\n\n<p><img src=\"python_sql_engine_images/planner.png\" alt=\"Planner Output\" /></p>\n\n<p>The logical plan is quite simple and contains the information required to convert it into a physical plan (execution).</p>\n\n<h2 id=\"executing\">Executing</h2>\n\n<p>Finally, we can actually execute the SQL query. The <a href=\"https://github.com/tobymao/sqlglot/blob/main/sqlglot/executor/python.py\">Python engine</a> 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.</p>\n\n<p>In order to keep things simple, it evaluates expressions with <code>eval</code>. Because SQLGlot was built primarily to be a transpiler, it was simple to create a \"Python SQL\" dialect. So a SQL expression <code>x + 1</code> can just be converted into <code>scope['x'] + 1</code>.</p>\n\n<p><img src=\"python_sql_engine_images/executor.png\" alt=\"Executor Output\" /></p>\n\n<h2 id=\"whats-next\">What's next</h2>\n\n<p>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 <a href=\"https://www.tpc.org/tpcds/\">TPC-DS</a>. If someone doesn't beat me to it, I may even take a stab at writing a Pandas/Arrow execution engine.</p>\n\n<p>I'm hoping that over time, SQLGlot will spark the Python SQL ecosystem just like Calcite has for Java.</p>\n\n<h2 id=\"special-thanks\">Special thanks</h2>\n\n<p>SQLGlot would not be what it is without it's core contributors. In particular, the execution engine would not exist without <a href=\"https://github.com/barakalon\">Barak Alon</a> and <a href=\"https://github.com/GeorgeSittas\">George Sittas</a>.</p>\n\n<h2 id=\"get-in-touch\">Get in touch</h2>\n\n<p>If you'd like to chat more about SQLGlot, please join my <a href=\"https://join.slack.com/t/tobiko-data/shared_invite/zt-1ma66d79v-a4dbf4DUpLAQJ8ptQrJygg\">Slack Channel</a>!</p>\n\n<hr />\n"}, "sqlglot.executor.execute": {"fullname": "sqlglot.executor.execute", "modulename": "sqlglot.executor", "qualname": "execute", "kind": "function", "doc": "<p>Run a sql query against data.</p>\n\n<h6 id=\"arguments\">Arguments:</h6>\n\n<ul>\n<li><strong>sql:</strong> a sql statement.</li>\n<li><strong>schema:</strong> database schema.\nThis can either be an instance of <code>Schema</code> or a mapping in one of the following forms:\n<ol>\n<li>{table: {col: type}}</li>\n<li>{db: {table: {col: type}}}</li>\n<li>{catalog: {db: {table: {col: type}}}}</li>\n</ol></li>\n<li><strong>read:</strong> the SQL dialect to apply during parsing (eg. \"spark\", \"hive\", \"presto\", \"mysql\").</li>\n<li><strong>tables:</strong> additional tables to register.</li>\n</ul>\n\n<h6 id=\"returns\">Returns:</h6>\n\n<blockquote>\n <p>Simple columnar data structure.</p>\n</blockquote>\n", "signature": "<span class=\"signature pdoc-code multiline\">(<span class=\"param\">\t<span class=\"n\">sql</span><span class=\"p\">:</span> <span class=\"nb\">str</span> <span class=\"o\">|</span> <span class=\"n\">sqlglot</span><span class=\"o\">.</span><span class=\"n\">expressions</span><span class=\"o\">.</span><span class=\"n\">Expression</span>,</span><span class=\"param\">\t<span class=\"n\">schema</span><span class=\"p\">:</span> <span class=\"n\">Union</span><span class=\"p\">[</span><span class=\"n\">Dict</span><span class=\"p\">,</span> <span class=\"n\">sqlglot</span><span class=\"o\">.</span><span class=\"n\">schema</span><span class=\"o\">.</span><span class=\"n\">Schema</span><span class=\"p\">,</span> <span class=\"n\">NoneType</span><span class=\"p\">]</span> <span class=\"o\">=</span> <span class=\"kc\">None</span>,</span><span class=\"param\">\t<span class=\"n\">read</span><span class=\"p\">:</span> <span class=\"n\">Union</span><span class=\"p\">[</span><span class=\"nb\">str</span><span class=\"p\">,</span> <span class=\"n\">sqlglot</span><span class=\"o\">.</span><span class=\"n\">dialects</span><span class=\"o\">.</span><span class=\"n\">dialect</span><span class=\"o\">.</span><span class=\"n\">Dialect</span><span class=\"p\">,</span> <span class=\"n\">Type</span><span class=\"p\">[</span><span class=\"n\">sqlglot</span><span class=\"o\">.</span><span class=\"n\">dialects</span><span class=\"o\">.</span><span class=\"n\">dialect</span><span class=\"o\">.</span><span class=\"n\">Dialect</span><span class=\"p\">],</span> <span class=\"n\">NoneType</span><span class=\"p\">]</span> <span class=\"o\">=</span> <span class=\"kc\">None</span>,</span><span class=\"param\">\t<span class=\"n\">tables</span><span class=\"p\">:</span> <span class=\"n\">Optional</span><span class=\"p\">[</span><span class=\"n\">Dict</span><span class=\"p\">]</span> <span class=\"o\">=</span> <span class=\"kc\">None</span></span><span class=\"return-annotation\">) -> <span class=\"n\">sqlglot</span><span class=\"o\">.</span><span class=\"n\">executor</span><span class=\"o\">.</span><span class=\"n\">table</span><span class=\"o\">.</span><span class=\"n\">Table</span>:</span></span>", "funcdef": "def"}, "sqlglot.executor.context": {"fullname": "sqlglot.executor.context", "modulename": "sqlglot.executor.context", "kind": "module", "doc": "<p></p>\n"}, "sqlglot.executor.context.Context": {"fullname": "sqlglot.executor.context.Context", "modulename": "sqlglot.executor.context", "qualname": "Context", "kind": "class", "doc": "<p>Execution context for sql expressions.</p>\n\n<p>Context is used to hold relevant data tables which can then be queried on with eval.</p>\n\n<p>References to columns can either be scalar or vectors.

+
+<p>SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine. It can be used to format SQL or translate between <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/dialects/__init__.py">19 different dialects</a> like <a href="https://duckdb.org/">DuckDB</a>, <a href="https://prestodb.io/">Presto</a>, <a href="https://spark.apache.org/">Spark</a>, <a href="https://www.snowflake.com/en/">Snowflake</a>, and <a href="https://cloud.google.com/bigquery/">BigQuery</a>. It aims to read a wide variety of SQL inputs and output syntactically correct SQL in the targeted dialects.</p>
+
+<p>It is a very comprehensive generic SQL parser with a robust <a href="https://github.com/tobymao/sqlglot/blob/main/tests/">test suite</a>. It is also quite <a href="#benchmarks">performant</a>, while being written purely in Python.</p>
+
+<p>You can easily <a href="#custom-dialects">customize</a> the parser, <a href="#metadata">analyze</a> queries, traverse expression trees, and programmatically <a href="#build-and-modify-sql">build</a> SQL.</p>
+
+<p>Syntax <a href="#parser-errors">errors</a> are highlighted and dialect incompatibilities can warn or raise depending on configurations. However, it should be noted that SQL validation is not SQLGlot’s goal, so some syntax errors may go unnoticed.</p>
+
+<p>Contributions are very welcome in SQLGlot; read the <a href="https://github.com/tobymao/sqlglot/blob/main/CONTRIBUTING.md">contribution guide</a> to get started!</p>

+
+<p>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:</p>

+
+<p>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 <a href="https://duckdb.org/">DuckDB</a>, <a href="https://prestodb.io/">Presto</a>, <a href="https://spark.apache.org/">Spark</a>, <a href="https://www.snowflake.com/en/">Snowflake</a>, and <a href="https://cloud.google.com/bigquery/">BigQuery</a>. </p>
+
+<p>Currently many of the common operations are covered and more functionality will be added over time. Please <a href="https://github.com/tobymao/sqlglot/issues">open an issue</a> or <a href="https://github.com/tobymao/sqlglot/pulls">PR</a> with your feedback or contribution to help influence what should be prioritized next and make sure your use case is properly supported.</p>

+<ul>
+<li><a href="https://github.com/tobymao/sqlglot/blob/main/README.md#install">Install SQLGlot</a> and that is all that is required to just generate SQL. <a href="#examples">The examples</a> show generating SQL and then executing that SQL on a specific engine and that will require that engine's client library.</li>
+<li>Find/replace all <code>from pyspark.sql</code> with <code>from <a href="">sqlglot.dataframe</a></code>.</li>
+<li>Prior to any <code>spark.read.table</code> or <code>spark.table</code> run <code>sqlglot.schema.add_table('&lt;table_name&gt;', &lt;column_structure&gt;)</code>.
+<ul>
+<li>The column structure can be defined the following ways:
+<ul>
+<li>Dictionary where the keys are column names and values are string of the Spark SQL type name.
+<ul>

+
+<p>While there is a SQL standard, most SQL engines support a variation of that standard. This makes it difficult
+to write portable SQL code. SQLGlot bridges all the different variations, called "dialects", with an extensible
+SQL transpilation framework. </p>
+
+<p>The base <code><a href="dialects/dialect.html#Dialect">sqlglot.dialects.dialect.Dialect</a></code> class implements a generic dialect that aims to be as universal as possible.</p>
+
+<p>Each SQL variation has its own <code>Dialect</code> subclass, extending the corresponding <code>Tokenizer</code>, <code>Parser</code> and <code>Generator</code>
+classes as needed.</p>

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

+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>

+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>

+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>

+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.

+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>

+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>

+represents a python time format and the output the target time format</li>
+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>
+<li><strong>comments:</strong> Whether or not to preserve comments in the output SQL code.
+Default: True</li>

+<h6 id="arguments">Arguments:</h6>
+
+<ul>
+<li><strong>time_mapping (dict):</strong> the dictionary of custom time mappings in which the key
+represents a python time format and the output the target time format</li>
+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>
+<li><strong>comments:</strong> Whether or not to preserve comments in the output SQL code.
+Default: True</li>

+represents a python time format and the output the target time format</li>
+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>

+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>

+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true

+<h2 id="motivation">Motivation</h2>
+
+<p>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.</p>
+
+<p>Text-based diff tools such as <code>git diff</code>, 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.</p>
+
+<p>Consider the following diff generated by Git:</p>
+
+<p><img src="sql_diff_images/git_diff_output.png" alt="Git diff output" /></p>
+
+<p>Semantically the query hasn’t changed. The two arguments <code>b</code> and <code>c</code> 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.</p>
+
+<p>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.</p>
+
+<p>The use cases I had in mind for SQL when I decided to embark on this journey of semantic diffing were the following:</p>
+
+<ul>

You can find a complete source code in the <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/diff.py">diff.py</a> 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.</p>

+<h2 id="the-search-for-a-solution">The Search for a Solution</h2>
+
+<p>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.</p>
+
+<p>If our elements have unique identifiers associated with them (for example, an element’s 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?</p>
+
+<p>To better illustrate the problem, consider comparing the following SQL expressions: <code>SELECT a + b + c, d, e</code> and <code>SELECT a - b + c, e, f</code>. Matching individual nodes from respective syntax trees can be visualized as follows:</p>
+
+<p><img src="sql_diff_images/figure_1.png" alt="Figure 1: Example of node matching for two SQL expression trees" />
+<em>Figure 1: Example of node matching for two SQL expression trees.</em></p>
+
+<p>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:</p>
+
+<ul>
+<li>Inserted nodes: <code>Sub</code> and <code>f</code>. These are the nodes from the target AST which do not have a matching node in the source AST.</li>
+<li>Removed nodes: <code>Add</code> and <code>d</code>. These are the nodes from the source AST which do not have a counterpart in the target AST.</li>
+<li>Remaining nodes must be identified as unchanged.</li>
+</ul>
+
+<p>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.</p>
+
+<h3 id="naive-brute-force">Naïve Brute-Force</h3>
+
+<p>The naïve 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’s actually much worse - O(n! ^ 2) - but I couldn’t come up with a name for it), so there is little need to explore this approach any further.</p>
+
+<h3 id="myers-algorithm">Myers Algorithm</h3>
+
+<p>After the naïve approach was proven to be infeasible, the next question I asked myself was “how does git diff work?”. 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’s 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’s a lot of material out there describing this algorithm in greater detail. I found James Coglan’s series of <a href="https://blog.jcoglan.com/2017/02/12/the-myers-diff-algorithm-part-1/">blog posts</a> to be the most comprehensive.</p>
+
+<p>Therefore, I had this “brilliant” (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.</p>
+
+<h2 id="change-distiller">Change Distiller</h2>
+
+<p>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].</p>
+
+<p>The algorithm consists of two high-level steps:</p>
+
+<ol>
+<li><strong>Finding appropriate matchings between pairs of nodes that are part of compared ASTs.</strong> Identifying what is meant by “appropriate” matching is also a part of this step.</li>
+<li><strong>Generating the so-called “edit script” from the matching set built in the 1st step.</strong> 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.</li>
+</ol>
+
+<p>The rest of this section is dedicated to the Python implementation of the steps above using the AST implementation provided by the SQLGlot library.</p>
+
+<h3 id="building-the-matching-set">Building the Matching Set</h3>
+
+<h4 id="matching-leaves">Matching Leaves</h4>
+
+<p>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’t pass basic matching criteria. Then, we pick pairs that scored the highest while making sure that each node is matched no more than once.</p>
+
+<p>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.</p>
+
+<p><img src="sql_diff_images/figure_2.gif" alt="Figure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes." />
+<em>Figure 2: Building a set of candidate matchings between leaf nodes. The third item in each triplet represents a similarity score between two nodes.</em></p>
+
+<p>First, let’s analyze the similarity score. Then, we’ll discuss matching criteria.</p>
+
+<p>The similarity score proposed by Fluri et al. [2] is a <a href="https://en.wikipedia.org/wiki/S%C3%B8rensen%E2%80%93Dice_coefficient">dice coefficient </a>applied to <a href="https://en.wikipedia.org/wiki/Bigram">bigrams</a> of respective node values. A bigram is a sequence of two adjacent elements from a string computed in a sliding window fashion:</p>

+
+<p>To compute a bigram given a tree node, we first transform the node into its canonical SQL representation,so that the <code>Literal(123)</code> node becomes just “123” and the <code>Identifier(“a”)</code> node becomes just “a”. 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.</p>
+
+<p>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:</p>
+
+<p><img src="sql_diff_images/matching_criteria_1.png" alt="Matching criteria for leaf nodes" /></p>
+
+<p>The two nodes are matched if two conditions are met:</p>
+
+<ol>
+<li>The node labels match (in our case labels are just node types).</li>
+<li>The similarity score for node values is greater than or equal to some threshold “f”. The authors of the paper recommend setting the value of “f” to 0.6.</li>
+</ol>
+
+<p>With building blocks in place, we can now build a matching set for leaf nodes. First, we generate a list of candidates for matching:</p>

+<p>To finalize the matching set, we should now proceed with matching inner nodes.</p>
+
+<h4 id="matching-inner-nodes">Matching Inner Nodes</h4>
+
+<p>Matching inner nodes is quite similar to matching leaf nodes, with the following two distinctions:</p>
+
+<ul>
+<li>Rather than ranking a set of possible candidates, we pick the first node pair that passes the matching criteria.</li>
+<li>The matching criteria itself has been extended to account for the number of leaf nodes the pair of inner nodes have in common.</li>
+</ul>
+
+<p><img src="sql_diff_images/figure_3.gif" alt="Figure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched." />
+<em>Figure 3: Matching inner nodes based on their type as well as how many of their leaf nodes have been previously matched.</em></p>
+
+<p>Let’s start with the matching criteria. The criteria is formalized as follows:</p>
+
+<p><img src="sql_diff_images/matching_criteria_2.png" alt="Matching criteria for inner nodes" /></p>
+
+<p>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 “t”. The recommended value for “t” 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.</p>
+
+<p>There are two additional heuristics associated with this matching criteria:</p>
+
+<ul>
+<li>Inner node similarity weighting: if the similarity score between the node values doesn’t pass the threshold “f” but the ratio of common leaf nodes (“t”) is greater than or equal to 0.8, then the matching is considered successful.</li>
+<li>The threshold “t” 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.</li>
+</ul>
+
+<p>We now only have to iterate through the remaining unmatched nodes and form matching pairs based on the outlined criteria:</p>

+
+<p>At this point, we should have the following 3 sets at our disposal:</p>
+
+<ul>
+<li>The set of matched node pairs.</li>
+<li>The set of remaining unmatched nodes from the source tree.</li>
+<li>The set of remaining unmatched nodes from the target tree.</li>
+</ul>
+
+<p>We can derive 3 kinds of edits from the matching set: either the node’s value was updated (<strong>Update</strong>), the node was moved to a different position within the tree (<strong>Move</strong>), or the node remained unchanged (<strong>Keep</strong>). Note that the <strong>Move</strong> 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 (<strong>Remove</strong>), while unmatched nodes from the target tree are the ones that were inserted (<strong>Insert</strong>).</p>
+
+<p>The latter two cases are pretty straightforward to implement:</p>

+
+<p>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 <a href="https://en.wikipedia.org/wiki/Longest_common_subsequence_problem">longest common subsequence </a>(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.</p>

+<h3 id="optimizations">Optimizations</h3>
+
+<p>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.</p>
+
+<p>There are still a few basic things we can do in our implementation to help improve performance:</p>
+
+<ul>
+<li>Refer to individual node objects using their identifiers (Python’s <a href="https://docs.python.org/3/library/functions.html#id">id()</a>) instead of direct references in sets. This helps avoid costly recursive hash calculations and equality checks.</li>
+<li>Cache bigram histograms to avoid computing them more than once for the same node.</li>
+<li>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.</li>
+</ul>
+
+<p>At the time of writing only the first two optimizations have been implemented, so there is an opportunity to contribute for anyone who’s interested.</p>
+
+<h2 id="alternative-solutions">Alternative Solutions</h2>
+
+<p>This section is dedicated to solutions that I’ve investigated, but haven’t tried.</p>
+
+<p>First, this section wouldn’t be complete without Tristan Hume’s <a href="https://thume.ca/2017/06/17/tree-diffing/">blog post</a>. Tristan’s 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 <a href="https://en.wikipedia.org/wiki/Dynamic_programming">dynamic programming</a> and <a href="https://en.wikipedia.org/wiki/A*_search_algorithm">A* search algorithm</a> to explore the space of possible matchings and pick the best ones. It seemed to have worked well for Tistan’s specific use case, but after my negative experience with the Myers algorithm, I decided to try something different.</p>
+
+<p>Another notable approach is the Gumtree algorithm by Falleri et al. [4]. I discovered this paper after I’d 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’t 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.</p>
+
+<h2 id="conclusion">Conclusion</h2>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>I’m 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’m interested to hear about your experience.</p>

+<h2 id="introduction">Introduction</h2>
+
+<p>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 <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/dialects/__init__.py">18 SQL dialects</a> and can execute all 24 <a href="https://www.tpc.org/tpch/">TPC-H</a> SQL queries. The parser and engine are all written from scratch using Python.</p>
+
+<p>This post will cover <a href="#why">why</a> I went through the effort of creating a Python SQL engine and <a href="#how">how</a> a simple query goes from a string to actually transforming data. The following steps are briefly summarized:</p>

+<li><a href="#executing">Executing</a></li>
+</ul>
+
+<h2 id="why">Why?</h2>
+
+<p>I started working on SQLGlot because of my work on the <a href="https://netflixtechblog.com/reimagining-experimentation-analysis-at-netflix-71356393af21">experimentation and metrics platform</a> 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 <a href="https://github.com/kayak/pypika">PyPika</a>, 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 <a href="[https://github.com/andialbrecht/sqlparse">sqlparse</a>, 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 <a href="https://craftinginterpreters.com/">Crafting Interpreters</a> and realized that I could use it as a guide towards creating my own SQL parser/transpiler.</p>
+
+<p>Why did I do this? Isn't a Python SQL engine going to be extremely slow?</p>
+
+<p>The main reason why I ended up building a SQL engine was...just for <strong>entertainment</strong>. 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.</p>
+
+<p>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 <a href="https://www.snowflake.com/en/">Snowflake</a> and seamlessly run it in CI on mock Python data. It's easy to mock data and create arbitrary <a href="https://en.wikipedia.org/wiki/User-defined_function">UDFs</a> because everything is just Python. Although the implementation is slow and unsuitable for large amounts of data (&gt; 1 million rows), there's very little overhead/startup and you can run queries on test data in a couple of milliseconds.</p>
+
+<p>Finally, the components that have been built to support execution can be used as a <strong>foundation</strong> for a faster engine. I'm inspired by what <a href="https://github.com/apache/calcite">Apache Calcite</a> 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 <a href="https://en.wikipedia.org/wiki/Abstract_syntax_tree">AST</a>/<a href="https://en.wikipedia.org/wiki/Query_plan">plan</a>. 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.</p>
+
+<p>Parts of SQLGlot's toolkit are being used today by the following:</p>

+
+<h2 id="how">How?</h2>
+
+<p>There are many steps involved with actually running a simple query like:</p>

+</code></pre>
+</div>
+
+<p>In this post, I'll walk through all the steps SQLGlot takes to run this query over Python objects.</p>
+
+<h2 id="tokenizing">Tokenizing</h2>
+
+<p>The first step is to convert the sql string into a list of tokens. SQLGlot's tokenizer is quite simple and can be found <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/tokens.py">here</a>. In a while loop, it checks each character and either appends the character to the current token, or makes a new token.</p>
+
+<p>Running the SQLGlot tokenizer shows the output.</p>
+
+<p><img src="python_sql_engine_images/tokenizer.png" alt="Tokenizer Output" /></p>
+
+<p>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.</p>
+
+<h2 id="parsing">Parsing</h2>
+
+<p>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 <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/parser.py">parser</a> is a handwritten <a href="https://en.wikipedia.org/wiki/Recursive_descent_parser">recursive descent</a> parser.</p>
+
+<p>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.</p>
+
+<p><img src="python_sql_engine_images/parser.png" alt="Parser Output" /></p>
+
+<p>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.</p>
+
+<h2 id="optimizing">Optimizing</h2>
+
+<p>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 <strong>optimize the AST directly</strong> for the following reasons:</p>
+
+<ol>
+<li><p>It's easier to debug and <a href="https://github.com/tobymao/sqlglot/blob/main/tests/fixtures/optimizer">validate</a> the optimizations when the input and output are both SQL.</p></li>
+<li><p>Rules can be applied a la carte to transform SQL into a more desirable form.</p></li>
+<li><p>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. <code>SELECT 1 + 1</code> and <code>SELECT 2</code>).</p></li>
+</ol>
+
+<p>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.</p>
+
+<p><img src="python_sql_engine_images/optimizer.png" alt="Optimizer Output" /></p>
+
+<p>The optimizer currently has <a href="https://github.com/tobymao/sqlglot/tree/main/sqlglot/optimizer">17 rules</a>. 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.</p>
+
+<p>Some example rules are:</p>
+
+<h3 id="qualify_tables-and-qualify_columns">qualify_tables and qualify_columns</h3>
+
+<ul>
+<li>Adds all db/catalog qualifiers to tables and forces an alias.</li>

+
+<p>After the SQL AST has been "optimized", it's much easier to <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/planner.py">convert into a logical plan</a>. The AST is traversed and converted into a <a href="https://en.wikipedia.org/wiki/Directed_acyclic_graph">DAG</a> consisting of one of five steps. The different steps are:</p>
+
+<h3 id="scan">Scan</h3>
+
+<p>Selects columns from a table, applies projections, and finally filters the table.</p>

+<p>Joins multiple tables together.</p>
+
+<p><img src="python_sql_engine_images/planner.png" alt="Planner Output" /></p>
+
+<p>The logical plan is quite simple and contains the information required to convert it into a physical plan (execution).</p>
+
+<h2 id="executing">Executing</h2>
+
+<p>Finally, we can actually execute the SQL query. The <a href="https://github.com/tobymao/sqlglot/blob/main/sqlglot/executor/python.py">Python engine</a> 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.</p>
+
+<p>In order to keep things simple, it evaluates expressions with <code>eval</code>. Because SQLGlot was built primarily to be a transpiler, it was simple to create a "Python SQL" dialect. So a SQL expression <code>x + 1</code> can just be converted into <code>scope['x'] + 1</code>.</p>

+
+<h2 id="whats-next">What's next</h2>
+
+<p>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 <a href="https://www.tpc.org/tpcds/">TPC-DS</a>. If someone doesn't beat me to it, I may even take a stab at writing a Pandas/Arrow execution engine.</p>
+
+<p>I'm hoping that over time, SQLGlot will spark the Python SQL ecosystem just like Calcite has for Java.</p>

+<h6 id="arguments">Arguments:</h6>
+
+<ul>
+<li><strong>time_mapping (dict):</strong> the dictionary of custom time mappings in which the key
+represents a python time format and the output the target time format</li>
+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>
+<li><strong>comments:</strong> Whether or not to preserve comments in the output SQL code.
+Default: True</li>

+represents a python time format and the output the target time format</li>
+<li><strong>time_trie (trie):</strong> a trie of the time_mapping keys</li>
+<li><strong>pretty (bool):</strong> if set to True the returned string will be formatted. Default: False.</li>
+<li><strong>quote_start (str):</strong> specifies which starting character to use to delimit quotes. Default: '.</li>
+<li><strong>quote_end (str):</strong> specifies which ending character to use to delimit quotes. Default: '.</li>
+<li><strong>identifier_start (str):</strong> specifies which starting character to use to delimit identifiers. Default: ".</li>
+<li><strong>identifier_end (str):</strong> specifies which ending character to use to delimit identifiers. Default: ".</li>
+<li><strong>identify (bool):</strong> if set to True all identifiers will be delimited by the corresponding
+character.</li>
+<li><strong>normalize (bool):</strong> if set to True all identifiers will lower cased</li>
+<li><strong>string_escape (str):</strong> specifies a string escape character. Default: '.</li>
+<li><strong>identifier_escape (str):</strong> specifies an identifier escape character. Default: ".</li>
+<li><strong>pad (int):</strong> determines padding in a formatted string. Default: 2.</li>
+<li><strong>indent (int):</strong> determines the size of indentation in a formatted string. Default: 4.</li>
+<li><strong>unnest_column_only (bool):</strong> if true unnest table aliases are considered only as column aliases</li>
+<li><strong>normalize_functions (str):</strong> normalize function names, "upper", "lower", or None
+Default: "upper"</li>
+<li><strong>alias_post_tablesample (bool):</strong> if the table alias comes after tablesample
+Default: False</li>
+<li><strong>unsupported_level (ErrorLevel):</strong> determines the generator's behavior when it encounters
+unsupported expressions. Default ErrorLevel.WARN.</li>
+<li><strong>null_ordering (str):</strong> Indicates the default null ordering method to use if not explicitly set.
+Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
+Default: "nulls_are_small"</li>
+<li><strong>max_unsupported (int):</strong> Maximum number of unsupported messages to include in a raised UnsupportedError.
+This is only relevant if unsupported_level is ErrorLevel.RAISE.
+Default: 3</li>
+<li><strong>leading_comma (bool):</strong> if the the comma is leading or trailing in select statements
+Default: False</li>
+<li><strong>max_text_width:</strong> The max number of characters in a segment before creating new lines in pretty mode.
+The default is on the smaller end because the length only represents a segment and not the true
+line length.
+Default: 80</li>
+<li><strong>comments:</strong> Whether or not to preserve comments in the output SQL code.
+Default: True</li>
