基本信息： 　　系统一:CentOS7.5 + mysql5.7.25 　　系统二:win10 + mysql5.7.25解压缩版

数据库表结构如下:

对MySql进行操作时报以下错误: 　　[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

一次性解决方案:

1. 查看sql_mode配置

select @@sql_mode

复制查询出来的信息:

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

2. 修改sql_mode配置

2.1 编辑 vi /etc/my.cnf 文件

windwos环境下,直接修改默认my.ini(解压缩版)或其他默认配置文件即可

[root@VM_18_167_centos ~]# vi /etc/my.cnf

2.2 在my.cnf 里面设置 sql_mode

复制查询到的sql_mode配置信息,并去掉ONLY_FULL_GROUP_BY,内容如下:

STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

设置sql_mode内容如下:

sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

重新启动mysql:

systemctl restart mysqld

再次执行插入语句,我们可以看到已经成功操作,不再报错了
