Leonid Fedorov	8f93fc3623	MCOL-5493: First portion of UBSan fixes (#2842 ) Multiple UB fixes	2023-06-02 17:02:09 +03:00
Sergey Zefirov	b53c231ca6	MCOL-271 empty strings should not be NULLs (#2794 ) This patch improves handling of NULLs in textual fields in ColumnStore. Previously empty strings were considered NULLs and it could be a problem if data scheme allows for empty strings. It was also one of major reasons of behavior difference between ColumnStore and other engines in MariaDB family. Also, this patch fixes some other bugs and incorrect behavior, for example, incorrect comparison for "column <= ''" which evaluates to constant True for all purposes before this patch.	2023-03-30 21:18:29 +03:00
