Quick answer

Create readable SQL with consistent clauses, indentation, aliases, and dialect-aware formatting.

Make structure visible

Place major clauses on separate lines and indent nested expressions. Reviewers should be able to identify selected columns, joins, filters, grouping, and ordering at a glance.

Choose a dialect

MySQL, PostgreSQL, SQL Server, SQLite, Oracle, and MariaDB differ. A dialect-aware formatter reduces surprising output around vendor-specific functions and syntax.

Formatting is not validation

A readable query may still reference missing objects, use incompatible types, or produce unintended results. Test against the target database and inspect the execution plan.
