Frequently Asked Questions
What SQL dialects are supported?
This tool supports standard SQL and common dialects including MySQL, PostgreSQL, SQL Server, and Oracle. The formatter handles most SQL syntax variations.
Can I minify SQL queries?
Yes, the SQL formatter can both beautify (add formatting) and minify (remove all whitespace) SQL queries. Minification reduces file size for production use.
Does SQL formatting affect performance?
No, SQL formatting only changes the visual presentation of your query. The database executes the same query regardless of whitespace and indentation.
Can I format complex SQL with JOINs?
Yes, the formatter handles complex queries with multiple JOINs, subqueries, CTEs (Common Table Expressions), and nested conditions with proper indentation.
Is my SQL query stored anywhere?
No, all SQL formatting happens in your browser. Your queries are never uploaded to any server, ensuring your database logic remains private.
