[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated..

[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

不知道为何，在用nivacat_mysql时，每次允许sql语句时都提示这个问题。

网上说什么my.cnf文件里修改sql_mode，把only_full_group_by去掉。

但是没有解决问题，因为我没有找到my.cnf。

后来找到了方法，解决问题了。

如下：

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

第一行是查看sql_mode。

第二行是修改。
