mysql版本升级为5.7.17，线下用的5.6版本，groupby报错处理

线上用的mysql版本为5.7.17&＃xff0c;线下用的5.6版本&＃xff0c;发现将程序上线后&＃xff0c;有些地方报这个错误

[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column &＃39;information_schema.PROFILING.SEQ&＃39; which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode&＃61;only_full_group_by

解决办法下my.cnf中添加以下几行

[mysqld]
sql_mode&＃61;&＃39;STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION&＃39;

在sql_mode 中去掉only_full_group_by

mysql> SET sql_mode &＃61;&＃39;STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION&＃39;;

mysql> select &＃64;&＃64;sql_mode; 

然后重启MySQL Server即可。

service mysqld restart
