SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine. It can be used to format SQL or translate between [21 different dialects](https://github.com/tobymao/sqlglot/blob/main/sqlglot/dialects/__init__.py) like [DuckDB](https://duckdb.org/), [Presto](https://prestodb.io/) / [Trino](https://trino.io/), [Spark](https://spark.apache.org/) / [Databricks](https://www.databricks.com/), [Snowflake](https://www.snowflake.com/en/), and [BigQuery](https://cloud.google.com/bigquery/). It aims to read a wide variety of SQL inputs and output syntactically and semantically correct SQL in the targeted dialects.

+It may not be possible to translate some queries between certain dialects. For these cases, SQLGlot may emit a warning and proceeds to do a best-effort translation by default. Transpilation is difficult and not all permutations are supported. If transpilation does not work, it may not be implemented yet. Well documented / tested PRs / issues are appreciated. Some transpilation cases that require db schemas are made possible through the optimizer but are not included in base transpilation:
