报错：[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregat

在Navicat中执行SQL语句时，报以下错：

[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

解决方法一：

在MySQL中执行：

select version(),

@@sql_mode;SET sql_mode=(SELECT REPLACE(@@sql_mode,‘ONLY_FULL_GROUP_BY’,’’));

这个方法只能解决当前的，最佳答案还是用解决方法二。

解决方法二：

修改MySQL的配置文件 my.ini，在[mysqld] 下面增加代码：

sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION’

如图：

修改完my.ini文件后需要重启一下MySQL服务，如果是windows系统，则执行：

net stop mysql

net start mysql
