mysql，5.7以上查询报错:ORDER BY clause is not in GROUP BY..this is incompatible with sql_mode=only_full_group_by

执行mysql命令查询时：

　　select * from table_name

错误信息如:

　　[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

　　mysql 5.7之后，查询如下:

　　select @@sql_mode;

　　如果:ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

默认设置了:

　　sql_mode=only_full_group_by

　　only_full_group_by:使用它就和oracle一样的group规则，select的列都要在group中，或本身就是聚合列(sum,avg,max,min)才行，只要把它去掉即可。

处理方法：直接在Mysql配置文件中修改(没有就增加)

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
