Sergei Petrunia	9c3eca8514	MDEV-21243: Join buffer: condition is checked in wrong place for range access ... In this scenario: - There is a possible range access for table T - And there is a ref access on the same index which uses fewer key parts - The join optimizer picks the ref access (because it is cheaper) - make_join_select applies this heuristic to switch to range: /* Range uses longer key; Use this instead of ref on key */ Join buffer will be used without having called JOIN_TAB::make_scan_filter(). This means, conditions that should be checked when reading table T will be checked after T is joined with the contents of the join buffer, instead. Fixed this by adding a make_scan_filter() check. (updated patch after backport to 10.3) (Fix testcase on Windows)	2020-01-12 15:48:46 +03:00
