MySQL5.7版本sql_mode=only_full_group_by问题解决办法

在服务器数据库查询使用了 GROUP BY 居然报出了

1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'XXX' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by, Time: 0.056000s

修改MySQL配置文件

Linux下my.cnf或Windows下My.ini
注意在[mysqld]段落下方添加以下代码：

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
