Frequently asked questions

1Which SQL dialects are supported?

PostgreSQL, MySQL, MariaDB, SQLite, Amazon Redshift, Spark SQL, Snowflake, T-SQL (SQL Server), BigQuery, IBM DB2, and standard SQL. The formatter adjusts syntax handling based on the dialect you select.

2Does it validate the SQL?

It formats the syntax but doesn't validate against a specific database schema. The formatter is syntax-aware, so malformed SQL may produce unexpected formatting but won't crash.

3Can I minify SQL with this?

Yes. Toggle the minify option to strip all unnecessary whitespace, useful for embedding queries in application code or sending them over the wire compactly.
