SQL queries embedded in code or sent over networks benefit from minification. Removing comments, extra whitespace, and newlines reduces query size. Minified SQL is hard to debug, so formatting adds indentation and line breaks. Supports both minification and formatting for standard SQL syntax.
Paste your SQL query into the input field and click 'Minify' to remove comments, extra whitespace, and line breaks. Click 'Format' to add proper indentation, uppercase keywords, and line breaks for readability.
SQL minification reduces query size for applications that embed SQL in source code, lowering network transmission overhead when sending queries to database servers. SQL formatting improves readability for code reviews, debugging complex queries with multiple JOINs and subqueries, documentation of database schemas, and creating readable stored procedures. Both operations are common in database development workflows.
The minifier uses regex-based removal of line comments (--) and block comments (/* */), followed by whitespace normalization. The formatter identifies SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) and applies consistent capitalization and indentation rules based on clause depth. Note: string literals containing comment-like sequences may be affected during minification.
SQL minification removes all comments (-- and /* */), extra whitespace, and line breaks, producing a compact single-line query. This reduces the data transmitted between your application and database server.
No. Minification only removes whitespace and comments - the SQL logic, keywords, and values remain identical. The database executes the minified query exactly the same as the original.
The tool handles standard SQL syntax compatible with PostgreSQL, MySQL, SQLite, SQL Server, and Oracle. It processes comments, string literals, and keywords for any SQL dialect.
