Line-break and indent SQL queries by clause for readability, or minify them to a single line for logging/storage. Uppercasing keywords is optional.
One-line or ORM-generated SQL becomes hard to read as joins pile up. Breaking it into clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, etc.) with consistent indentation makes it instantly clear which tables join on what condition and what the WHERE filters are β speeding up code review and debugging.
Line breaks are inserted before major clauses (SELECT/FROM/WHERE/JOIN variants/GROUP BY/ORDER BY/HAVING/LIMIT, etc.), and AND/OR are indented one level to set conditions apart. Comma-separated column lists each get their own line, and parenthesized content (subqueries, etc.) gets an extra indent level. This is a token-based formatter, not a full SQL parser β deeply nested subqueries or vendor-specific syntax may need a quick manual touch-up after formatting.
Minify strips comments and collapses unnecessary whitespace/line breaks into a single line. Handy for logging a query, shrinking stored-procedure/migration script size, or pasting a one-liner into another tool. Content inside string literals (quoted values) is preserved exactly, so your data values are never altered.
