What sql minifier does
Minifying SQL collapses the statement onto one line and removes comments. It is useful when a query has to travel somewhere that dislikes newlines — an environment variable, a single-line JSON field, a log message, or a migration tool that reads one statement per line.
Minified SQL is harder for a person to read, so treat it as a transport format rather than something to check into a repository. Keep the formatted version as the source of truth; string literals are preserved exactly, so a minified statement runs identically to the one you pasted.
Frequently asked questions
Yes. A line comment cannot survive being collapsed onto one line, because everything after it would be commented out, so both line and block comments are dropped.
It should. String literals are preserved byte for byte and only whitespace between tokens is collapsed. Test anything important, particularly if the original relied on formatting inside a literal.
Prefer not to. A minified statement produces unreadable diffs and hides changes during review. Keep the formatted version as the source and minify at the point of use.
