Thanks, do you have a reference for SQL grammar - I've had no success finding an official source.

Ibis has sqlglot for parsing and rewriting SQL query graphs; and there's sql-to-ibis: https://github.com/ibis-project/ibis/issues/9529

sqlglot: https://github.com/tobymao/sqlglot :

> SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine [written in Python]. It can be used to format SQL or translate between 24 different dialects like DuckDB, Presto / Trino, Spark / Databricks, Snowflake, and BigQuery. It aims to read a wide variety of SQL inputs and output syntactically and semantically correct SQL in the targeted dialects.

You can google SQL grammar. But here is the 2025: https://standards.iso.org/iso-iec/9075/-2/ed-6/en/

Thank you! My Google foo did not find this.

Google search sucks really bad now for very specific searches.
