Example
Example Use
Formatting a Complex JOIN Query
You inherit a single-line query: SELECT u.id,u.name,o.total FROM users u LEFT JOIN orders o ON u.id=o.user_id WHERE o.total>100 ORDER BY o.total DESC. Paste it into the formatter to produce a multi-line version with each clause on its own line, JOIN conditions clearly aligned, and WHERE and ORDER BY easy to scan at a glance.

FAQ
Frequently Asked Questions
Which SQL dialects does the formatter support?
The formatter supports standard SQL including SELECT, INSERT, UPDATE, DELETE, JOIN, GROUP BY, HAVING, and subqueries. It works for most common dialects including MySQL, PostgreSQL, SQLite, and SQL Server syntax.
Does the SQL Formatter execute my queries?
No. The tool only formats the text of your SQL query — it does not connect to any database or execute statements. Your queries are never run.
Is my SQL sent to a server?
No. All formatting runs locally in your browser. Your SQL queries are never sent to BuBird servers.
Can it format long queries with multiple JOINs?
Yes. The formatter handles complex queries including multiple JOIN clauses, nested subqueries, CTEs (WITH clauses), and window functions, breaking them into readable indented sections.
Can I also minify SQL with this tool?
The primary focus is formatting for readability. For compressing SQL into a single line, use the Minify tool or remove whitespace manually.
