SQL Query Formatting
Complex SQL queries with multiple JOINs, subqueries, and CTEs become unreadable without proper formatting. Well-structured SQL reveals query logic and makes optimization and debugging easier.
Formatting Elements
- Keyword alignment: SELECT, FROM, WHERE, JOIN on consistent positions
- Clause indentation: Subqueries and CTEs properly nested
- Column lists: One column per line with trailing commas
- JOIN structure: ON conditions clearly associated with their JOINs
Dialect Support
Different databases have slightly different SQL syntax. Our formatter handles MySQL, PostgreSQL, SQL Server, and standard SQL, recognizing dialect-specific functions and keywords.
Keyword Case
Choose uppercase keywords (SELECT, WHERE) for traditional style, lowercase for modern conventions, or preserve existing case. Consistent keyword casing improves readability.
Performance Analysis
Formatted queries make execution plans easier to understand. When optimizing slow queries, proper formatting helps identify problematic JOINs, missing indexes, and inefficient subqueries.
