错误:this is incompatible with sql_mode=only_full_group_by

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'H5APP_WORKREPORT.c.id' 
which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

原因:

这个错误的原因是高版本mysql(客户服务器版本5..7.18)默认的sql_mode包含ONLY_FULL_GROUP_BY,这个属性保证了select到的列都在group by中出现.

 

查看SQL_MODE的语句如下:

select @@GLOBAL.sql_mode;

 

 

解决方案:

方法一.可以使用SQL语句暂时修改SQL_MODE,重启mysql后就会事项:

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'

 

方法二:修改mysql配置文件,通过手动添加sql_mode的方式强制指定不需要ONLY_FULL_GROUP_BY属性,my.cnf位于etc文件夹下,vim下光标移到最后,

添加如下:

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