Mysql5.7遇到运行sql order by 使用 group字段时出错的解决办法

[Err] 1055 - nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'swh.attendee.attendee_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

　　解决办法：

1、在mysql中使用下列查询语句：

select @@sql_mode

2、在my.cnf（my.ini）中修改配置项：sql_mode（把查询到的值删掉only_full_group_by这个选项，其他的都复制过去）：

sql_mode=STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
