MySQL Error 3597: Misplaced Ordering in Window Queries
Description
MySQL Error 3597 indicates a syntax issue where you are attempting to use `ASC` or `DESC` (ordering directives) directly within a `GROUP BY` clause while your query also employs window functions. This error occurs because MySQL expects ordering for window functions to be specified either within the `OVER()` clause or in the main query's `ORDER BY` clause, not within `GROUP BY`.
Error Message
ASC or DESC with GROUP BY isn't allowed with window functions; put ASC or DESC in ORDER BY
Known Causes
3 known causesOrdering within GROUP BY
This occurs when an `ASC` or `DESC` clause is mistakenly added directly to the `GROUP BY` clause in a query that also utilizes window functions.
Incorrect Syntax for Window Ordering
The ordering for window functions or the final result set must be specified in the query's main `ORDER BY` clause or within the `OVER()` clause, not `GROUP BY`.
Legacy Query Adaptation Issues
Modifying older queries that used `GROUP BY` with `ASC`/`DESC` for ordering, without updating them to modern window function syntax, can trigger this error.
