Frequently Asked Questions

What SQL dialects does this formatter support?
This formatter works with standard ANSI SQL and is compatible with queries from MySQL, PostgreSQL, SQL Server, Oracle, SQLite, and MariaDB. It handles SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and most other SQL statements.
Does this tool validate my SQL syntax?
Yes, the formatter detects syntax errors and reports them clearly. If your query has issues, it will show an error message indicating the problem area so you can fix it quickly.
Is my SQL data sent to any server?
No, all formatting and validation happens entirely in your browser using JavaScript. Your SQL queries are never uploaded, stored, or transmitted anywhere. This makes it safe for sensitive database queries.
Can I use this to minify SQL for production?
Yes, the Minify option removes all extra whitespace and comments from your SQL query, creating a compact single-line version ideal for stored procedures and production environments where file size matters.
