Understanding SQL Formatter
SQL formatting adds line breaks and indentation to make a query easier to review. It does not execute the statement, validate it against a database schema, or guarantee compatibility with a particular SQL dialect.
Formatting versus validation
A formatter can make clauses and nested expressions clearer while leaving an invalid column name or unsupported function untouched. Run the query against the intended database or its parser for authoritative validation.
SQL dialects differ
PostgreSQL, MySQL, SQL Server, SQLite, and other systems differ in quoting, functions, data types, pagination, and procedural syntax. Review formatted output when a query uses vendor-specific features.
Protect production data
Remove credentials, customer values, internal hostnames, and confidential table data before sharing a query. Formatting changes presentation only; it does not anonymize literals or comments.
