which is not functionally dependent on columns in GROUP BY clause

报错信息：which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by



在对连接表进行select查找时出现以上报错信息。



打开【my.ini】文件



添加如下代码在【mysqld】中



sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
 保存，重启mysql即可
