mysql 1055 的错误

一、Err1055，出现这个问题每每是在执行sql语句时候，在最后一行会出现这个问题。

[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

 解决方法：
在 /etc/my.cnf 文件里加上以下：
sql_mode='NO_ENGINE_SUBSTITUTION'

而后，重启Mysql服务就能够解决了！

也能够 用 any_value() 方法解决
