Dave Gosselin	02e38e2ece	MDEV-33971 NAME_CONST in WHERE clause replaced by inner item ... Improve performance of queries like SELECT * FROM t1 WHERE field = NAME_CONST('a', 4); by, in this example, replacing the WHERE clause with field = 4 in the case of ref access. The rewrite is done during fix_fields and we disambiguate this case from other cases of NAME_CONST by inspecting where we are in parsing. We rely on THD::where to accomplish this. To improve performance there, we change the type of THD::where to be an enumeration, so we can avoid string comparisons during Item_name_const::fix_fields. Consequently, this patch also changes all usages of THD::where to conform likewise.	2024-07-10 17:23:43 -04:00
