mysql从5.6升级到5.7后出现：插入数据和修改数据时出错

这样只是暂时修改，永久生效可以改配置文件my.cnf 然后 service mysqld restart 生效
【原因】
可能是
1、在sql查询语句中不需要group by的字段上使用any_value()函数
这种对于已经开发了不少功能的项目不太合适，毕竟要把原来的sql都给修改一遍
2、DISTINCT和order by都会对数据进行排序操作，所以会产生冲突
在sql语句中使用DISTINCT时不使用order by进行排序，获取结果集后通过php进行数据的排序，同时也提高了mysql的性能。同时group by，limit和其中的一起搭配使用也会导致错误。
mysql5.7版本中，如果DISTINCT和order by一起使用将会报3065错误，sql语句无法执行。这是由于5.7版本语法比之前版本语法要求更加严格导致的。
3、
MySQL Server 默认开启了 sql_mode=only_full_group_by 模式，此模式要求 group by 字段必须出现在查询项中（select），否则就会报出该错误。因为GROUP BY处理变得更加复杂，包括检测功能依赖性。
【补充】
查询sql_mode的方式
查询全局sql_mode
SELECT @@GLOBAL.sql_mode;
查询当前会话sql_mode
SELECT @@SESSION.sql_mode;
...
