mysql：sql_mode=“only_full_group_by”

select name,gmt_created from db_test group by name

数据库里调用如上sql,结果出错，显示“SELECT list is not in GROUP BY clause and contains nonaggregated column”
意思是让我改成

select name,gmt_created from db_test group by name，gmt_created

如上，那就失去了原来分组的意义了，原因是数据库配置sql_mode=“only_full_group_by”，
在不能修改数据库配置的情况下，用了distinct解决问题
