解决MySQL-sql_mode=only_full_group_by报错

具体报错:[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
问题解决方案:
1、不能一次性解决

select version(), @@sql_mode;
SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

2、 能一次性解决问题
修改 my.cnf 文件的 sql_mode
查找 my.cnf 文件: find / -name my.cnf 或者 whereis my.cnf
获取 sql_mode字段内容: SELECT @@sql_mode;
去掉 sql_mode字段中的 only_full_group_by
编辑 my.cnf: vim /etc/my.cnf 将上一步骤的 sql_mode 字段内容添加至 my.cnf
保存,重启: service mysqld restart
sql_mode 字段参考:

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