mysql clause and contains nonaggregated column code example

Example 1: GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

Example 2: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
