Frequently Asked Questions

Why format SQL queries?

Formatted SQL is easier to read, debug, and maintain. Consistent indentation helps spot errors faster.

What SQL dialects are supported?

The tool supports MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, Spark, TSQL and more.

Does SQL formatting change the query's semantics or execution result?

No. SQL formatting only adjusts whitespace (newlines, indentation, alignment) and does not change the query's meaning or execution result. The formatted SQL is semantically identical to the original. Formatting makes queries easier to review, understand, and spot potential logical errors like missing WHERE clauses.

What are the collaboration benefits of consistently formatting SQL?

Benefits of uniformly formatted SQL: code reviews are easier because logic issues are visible rather than format noise; Git diffs only show real logical changes, not whitespace; new team members understand complex queries faster; fewer low-level mistakes caused by inconsistent formatting. Recommend integrating a tool like sqlfluff into the CI/CD pipeline to automatically check and format SQL, keeping the codebase consistent.
