Columns not named in group by clause should increase warnings in P_S tables

    XMLWordPrintable

    Details

      Description

      Non aggregated columns not named in GROUP BY clause are accepted in mysql unless only_full_group_by is set.

      Finding those queries in application code is hard.

      Thus it would be nice when those queries would rise a warning in P_S events_statements_history* tables so they could be found and eliminated before setting sql_mode = 'only_full_group_by'

      select a, b, count from test group by a;
      OK
      select * from performance_schema.events_statements_history where warnings > 0;
      -> query should be listed.

      List those queries in P_S.events_statements_history* tables.
