解决方法 ：

执行SET GLOBAL sql_mode = ''; 把sql_mode 改成非only_full_group_by模式。

验证是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode

mysql> select @@global.sql_mode;
+-------------------------------------------------------------------------------
-----------------------------------------------+
| @@global.sql_mode
                                               |
+-------------------------------------------------------------------------------
-----------------------------------------------+
| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_Z
ERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+-------------------------------------------------------------------------------
-----------------------------------------------+
1 row in set (0.04 sec)

mysql>

mysql> SET sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY
_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
Query OK, 0 rows affected, 1 warning (0.04 sec)

If you want to affect on all client, please use “@@global”, for example:

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