Frequently Asked Questions
Does SQL formatting affect query performance?
No. SQL formatting is purely cosmetic — it changes whitespace and capitalization but not the query logic. The database engine sees the same query regardless of formatting.
Which SQL dialects are supported?
The formatter supports standard SQL (ANSI) and is compatible with most major dialects including MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle.
What SQL formatting conventions should I follow?
Common conventions: uppercase SQL keywords (SELECT, FROM, WHERE), one clause per line, consistent indentation for subqueries, and aliases for long table or column names. Consistency within a team matters more than any specific style.
