From 1570c6e3e04fae7afd33748ce741f726e4fcfaa2 Mon Sep 17 00:00:00 2001 From: Sergei Golubchik Date: Wed, 5 Jul 2023 21:51:52 +0200 Subject: [PATCH] bugfix: join a=b where cast(a as type_of_b) can produce NULL optimizer implicitly assumed that if `a` in `a=b` is not NULL, then it's safe to convert `a` to the type of `b` and search the result in the index(b). which is not always the case, as converting a non-null value to a different type might produce NULL. And searching for NULL in the index might find NULL there, so NULL will be equal to NULL, making `a=b` behave as if it was `a<=>b` --- mysql-test/main/subselect_cache.result | 4 +-
