    Description

      I can't say for sure whether this can be considered an actual bug.

      In MySQL, ANSI mode is equivalent to REAL_AS_FLOAT, PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE, ONLY_FULL_GROUP_BY.

      In MariaDB, ONLY_FULL_GROUP_BY doesn't appear to be included.

      I know it's not hard to include in the command, but is this a deliberate difference with MySQL or an oversight?

            It is more of a difference between MySQL and MySQL. ONLY_FULL_GROUP_BY was added to ANSI alias in MySQL 5.7, it wasn't there before.

            Thanks.

            Is this the sort of thing worth adding as a feature request?

            Yes, but it's not that simple. In MySQL it happened in the scope of WL#2489.
            The main complexity is not to enable the flag but to make this mode work as expected. The old naïve implementation was not good enough to have it enabled as a part of ANSI.

            Doing this is MariaDB is part of MDEV-11588
