Frequently Asked Questions
Does it support different SQL dialects?
Yes — common dialects including MySQL, PostgreSQL, SQL Server (T-SQL), and standard ANSI SQL are supported, since formatting conventions differ slightly between them.
Will formatting change my query's logic or results?
No — only whitespace, indentation, and line breaks are adjusted; keywords, table names, and query logic are left completely unchanged.
Can it format very long queries with multiple joins and subqueries?
Yes, deeply nested queries with multiple `JOIN`s and subqueries are indented hierarchically so the structure becomes easy to follow.
