Frequently Asked Questions
What SQL dialects are supported?
The formatter handles standard SQL syntax that works across MySQL, PostgreSQL, SQLite, and SQL Server. Dialect-specific syntax is preserved as-is.
Does formatting change query behavior?
No. Formatting only adds whitespace and line breaks. The SQL logic remains identical.
Can it handle subqueries?
Yes. Nested subqueries and CTEs (WITH clauses) are properly indented to show their structure.
Why format SQL?
Formatted SQL is significantly easier to read, review, and debug. It helps identify logic errors, missing conditions, and unnecessary joins.
