Frequently Asked Questions

How do I format SQL queries online for free?

Paste your messy SQL query, select indentation (2 or 4 spaces), and click "Format". The tool automatically adds proper line breaks, indents keywords, aligns clauses, and makes the query readable. Perfect for debugging and code reviews.

Can this format complex SQL queries with multiple JOINs?

Yes! The formatter handles complex queries with multiple JOINs, subqueries, UNION statements, CTEs (WITH clauses), nested queries, and CASE expressions. Each JOIN is properly indented and aligned, making even the most complex queries readable.

Does this work with MySQL, PostgreSQL, and SQL Server?

Yes! The formatter works with standard SQL syntax used by MySQL, PostgreSQL, SQL Server, Oracle, SQLite, and other databases. It recognizes common SQL keywords and structures across all major database systems.

What is the best indentation for SQL queries?

Most SQL developers use 2 or 4 spaces. 2 spaces keeps queries compact, 4 spaces improves readability for complex queries. The formatter lets you choose. Never use tabs in SQL - stick with spaces for consistency across editors.

Can I format stored procedures and CTEs?

Yes! The formatter handles stored procedures, CTEs (Common Table Expressions with WITH), window functions, and other advanced SQL features. It properly indents nested structures and makes procedure logic clear.

Will formatting change how my query executes?

No, formatting only adds whitespace - it doesn't change query logic, performance, or results. The formatted query executes identically to the original. It's purely for human readability and code maintenance.
