Frequently Asked Questions

Which SQL dialects are supported?

This formatter supports standard SQL syntax that works across most major databases including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Some database-specific features may not be formatted exactly according to each dialect's conventions.

Will formatting change my query logic?

No, formatting only changes whitespace, indentation, and keyword casing. It does not modify your query's logic, structure, or execution. The formatted query will produce identical results to the original.

Can I use this for complex queries with subqueries?

Yes, the formatter handles complex queries including nested subqueries, CTEs (Common Table Expressions), JOINs, and window functions. It intelligently indents nested structures to make them more readable.
