Frequently asked questions

Does the formatter execute my SQL?

No. It only processes the text in your browser and never connects to a database.

Does it support every SQL dialect?

It is a lightweight common-SQL formatter. Always review dialect-specific syntax for SQL Server, PostgreSQL or another database.

Does validation prove a query is safe?

No. It is a structural check, not a security review, query-plan analysis or SQL injection scanner.
