mysql关闭only_full_group_by

1.临时生效

#查看
#1
show variables like '%sql_mode%';
#2
SELECT @@GLOBAL.sql_mode;
#3
SELECT @@SESSION.sql_mode;
#去除only_full_group_by
set @@GLOBAL.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';
set @@SESSION.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

#在查询语句前加
set @@SESSION.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

2.永久生效

sql命令 查询 sql_mode设置 

show variables like '%sql_mode%';

将查询sql_mode的结果去除only_full_group_by配置到下边文件内

找到mysql的配置文件 my.ini/my.cnf

添加配置

# 关闭ONLY_FULL_GROUP_BY
sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
