Database error: Invalid SQL: SELECT TEAM_NO, event.EVENT_PTR FROM relay left join event on event.EVENT_PTR=relay.EVENT_PTR where TEAM_NO="12401514" group by event_no order by RELAY_NO
MySQL Error: 1055 (Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'zzzz_db123.event.EVENT_PTR' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by)
