MySQL [Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause

Posted 2021-11-27 51python

方案1：

修改sql_mode的值

set sql_mode = ‘‘;
set sql_mode = ‘NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES‘;

再次执行刚才的语句，就不会报错了。

方案2：

在my.cnf添加如下：

[mysqld]

sql_mode=‘NO_AUTO_VALUE_ON_ZERO,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE, ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,PIPES_AS_CONCAT,ANSI_QUOTES‘

如果没有my.cnf,有my.ini.txt也行。
