1055

我现在使用的是mysql5.7的版本，每次执行sql语句的时候会报如下的问题

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

我的解决思路为：

• 首先找到mysql的配置文件 my.cnf

find / -name my.cnf

• 打开 my.cnf
• 添加如下代码

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

• 重启mysql服务

systemctl restart mysqld
