[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains 的问题 MySQL

这几天学习mysql时遇到不少问题，其中一个就是查询sql运行时会出现一个错误，但也有查询结果，在百度之后发现了一个有效的解决方法，下面是报错信息：[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

解决方案：

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

之后再运行

[code]show variables like "sql_mode";

set sql_mode='';
set sql_mode='NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES';

然后再运行自己的sql就不会出现之前的错误了
