Frequently Asked Questions

Why format SQL queries?
Formatted SQL is significantly easier to read, debug, and review. Long unformatted queries are a common source of logic errors that are hard to spot.
Does this support all SQL dialects?
The formatter handles standard SQL syntax (ANSI SQL) and works with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle for most common statements.
