Frequently Asked Questions

Which SQL dialects are supported?

The formatter supports standard SQL with extensions for PostgreSQL, MySQL, SQLite, and SQL Server. Vendor-specific syntax like LIMIT, OFFSET, TOP, and string concatenation operators are all handled.

Will formatting change my query results?

No — formatting only changes whitespace and casing. The logical structure, execution plan, and results of your query are completely unchanged.
