Format SQL so clauses, expressions and nesting are easier to read

Readable SQL helps developers review SELECT lists, joins, conditions and nested expressions without changing the intended query logic.

Formatting is presentation only. A clean-looking query can still be incorrect, inefficient or unsafe.

Useful SQL-formatting workflows

  • Review generated or minified SQL.
  • Prepare queries for code review.
  • Make nested statements easier to inspect during debugging.

What to verify

  • Select the correct SQL dialect where supported.
  • Run validation separately for syntax checking.
  • Test query behavior and performance in an appropriate environment.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
