MYSQL5.7版本sql_mode=only_full_group_by问题

错提示：Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'shop_tb.a.sub_total_number' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

1、查看sql_mode

　　SELECT @@global.sql_mode;

2、去掉ONLY_FULL_GROUP_BY，重新设置值。

　　SET @@global.sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
