SQL Formatter
SQL (Structured Query Language) is the standard language for managing and querying relational databases. Properly formatted SQL is easier to read, debug, and maintain, especially for complex queries with multiple joins and subqueries.
This tool formats SQL queries with configurable indentation and dialect awareness. It handles SELECT, INSERT, UPDATE, DELETE statements, JOINs, subqueries, CASE expressions, and comments. Choose between Standard SQL, MySQL, and PostgreSQL dialects.
How it works
SQL formatting follows a set of conventions: major clauses (SELECT, FROM, WHERE, JOIN) start on new lines, column lists are indented, and logical operators (AND, OR) align under their parent clause.
Use cases
- Making complex queries readable during code review
- Formatting stored procedures and database migrations
- Standardizing SQL style across a development team
- Debugging long queries by visually separating clauses
