Frequently Asked Questions
Which SQL databases are supported?
Our formatter supports MySQL, PostgreSQL, SQL Server, Oracle, SQLite, and most standard SQL dialects. It handles common SQL syntax including SELECT, JOIN, WHERE, GROUP BY, and subqueries.
Can I customize the formatting style?
Yes! You can adjust the indent size from 2 to 8 spaces. Keywords are automatically capitalized following SQL best practices.
Does it validate SQL syntax?
The formatter focuses on beautifying code rather than validation. It will format invalid SQL but won't check for syntax errors. Use your database's parser for validation.
Can it format stored procedures?
Yes, the formatter handles stored procedures, functions, triggers, and other complex SQL objects with proper indentation.
How does it handle comments?
SQL comments (both -- single-line and /* multi-line */) are preserved in their original positions during formatting.
Can I format multiple queries at once?
Yes! Paste multiple queries separated by semicolons and all will be formatted with proper spacing between them.
Is my SQL code stored or uploaded?
No. All formatting happens locally in your browser. Your SQL code never leaves your device and is not stored or transmitted anywhere.
Does it work with CTEs (Common Table Expressions)?
Yes, the formatter properly handles CTEs (WITH clauses), subqueries, and complex nested query structures.
