SQL Formatter Description
Format and beautify your SQL queries for better readability. Supports various SQL dialects.
How to use
- Paste your unformatted or minified SQL query into the editor.
- Choose your SQL dialect (MySQL, PostgreSQL, T-SQL, etc.) if available.
- The tool will indent keywords and align clauses for better readability.
Common Scenarios
- Cleaning up complex, nested queries for code review.
- Formatting auto-generated SQL from ORMs (like Hibernate or Sequelize).
- Debugging long SQL scripts by making the structure clear.
Data Structure
The tool parses the SQL string into tokens (keywords, identifiers, literals, operators) and then reconstructs it.
Principles
It uses a SQL lexer and parser to understand the query structure, then applies rule-based formatting to place keywords on new lines.
