Frequently Asked Questions

Which SQL database dialects are supported by the formatter?

The formatter supports standard SQL plus MySQL, PostgreSQL, SQL Server, Oracle variants, and MariaDB for maximum compatibility.

Will formatting change query behavior?

No, formatting only changes whitespace and capitalization. Query logic and results remain identical.

Can it fix SQL syntax errors?

No, formatters beautify valid SQL. They may highlight errors but cannot auto-fix syntax issues.

Does it work with stored procedures?

Yes, most formatters handle complex SQL including stored procedures, functions, and triggers.
