Mysql 5.7版本报错 1055

错误提示：

[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：

对于错误err1055查询了很久，说是5.7版本开始对sql的分组查询有了一个语法的检测，对于之前的sql就会出现一些错误，只要吧sqlmodel中的only_full_group_by去掉就行了。

#查询sqlmodel模式：select @@global.sql_mode

设置sqlmodel 模式：SET GLOBAL  sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
