Mysql8 SQLSTATE[42000] sql_mode=only_full_group_by错误解决办法

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

解决方法一：

打开navcat，
用sql查询：

 select @@global.sql_mode

查询出来的值为：

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

去掉ONLY_FULL_GROUP_BY，重新设置值

set @@global.sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

解决方法二：

linux

nano mysql.conf.d/mysqld.cnf

在底部添加

character-set-server = utf8
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION 

Ctrl+O保存并Ctrl+X退出，重启mysql

systemctl restart mysql

windows
打开my.ini文件，在[mysqld]块下添加

[mysqld]
character-set-server = utf8
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION 

重启mysql生效。
