💡 Frequently Asked Questions
Q: Does SQL formatting change query execution output?
No. Formatting only adjusts whitespaces, line breaks, and keyword capitalization. SQL engine execution plan remains identical.
Q: Are my database queries stored or logged?
No, all SQL parsing happens locally inside your browser. No queries are uploaded or logged.
Q: Which SQL dialects are supported?
Works with Standard ANSI SQL, PostgreSQL, MySQL, SQLite, Microsoft SQL Server, MariaDB, and Oracle SQL.
Q: Why should SQL keywords be in UPPERCASE?
UPPERCASE keywords create a clear visual distinction between SQL grammar commands and database schema column/table names.
