MYSQL5.7版本sql_mode=only_full_group_by问题

错误提示

1055 - Expression #1 of 
SELECT list is not in GROUP BY clause and contains nonaggregated column 'jovemes.p4.Rkey' which is not functionally 
dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by sql_mode=only_full_group_by

解决办法

1、查看sql_mode

mysql> select @@sql_mode;

查询出来的值为：

mysql> select @@sql_mode;
+-------------------------------------------------------------------------------------------------------------------------------------------+
| @@sql_mode                                                                                                                                |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| 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 |
+-------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

2、去掉ONLY_FULL_GROUP_BY，重新设置值

mysql> 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';
Query OK, 0 rows affected (0.00 sec)
