MySQL 5.7版本 sql_mode=only_full_group_by 問題

具體錯誤：

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column '庫.表.字段' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

查看：

查看 MySQL 的 global.sql_mode

select @@global.sql_mode;

顯示以下：ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

解決

修改 global.sql_mode

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';
