Frequently asked questions
Does minifying SQL change how it executes?
No. Whitespace and comments are insignificant to the database engine, so a minified query returns exactly the same result.
Are string values kept intact?
Yes. Content inside single quotes, double quotes and backticks is preserved exactly, including spaces and comment-like text.
Can I restore a formatted version later?
Use our free SQL Formatter tool to expand any minified query back into readable, indented SQL.
