sql语句报错问题

#1055 - Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column \'cash.sdb_login_log.id\' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

官方文档的解决方法：

文档链接：

https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sql-mode-setting

 

 

查询mysql服务器版本：
select @@version
显示：
5.7.10
select @@GLOBAL.sql_mode;
显示结果：
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

#查看sql_mode的语法
select @@GLOBAL.sql_mode;
select @@SESSION.sql_mode;

#修改sql_mode的语法
SET GLOBAL sql_mode = \'modes\';
SET SESSION sql_mode = \'modes\';
或者 set sql_model=‘’;

 

但是此方法并不是根本解决方案，当你的mysql再次重启后又会出现此问题，
