报错信息

在Linux环境下的MySQL里执行SQL语句报如下错误：[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

解决办法

修改Linux 环境 MySQL下的配置文件：/etc/my.cnf

（1）获取 sql_mode字段内容： SELECT @@sql_mode;

SELECT @@sql_mode;

（2）去除 sql_mode字段中的 only_full_group_by

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

（3）编辑配置文件： vim /etc/my.cnf，将去除 only_full_group_by后的 sql_mode 内容值添加至 my.cnf文件中，保存后退出

（4）重启MySQL服务：

systemctl restart mysqld
