经过查询资料发现group by 聚合操作的时候，进行查询操作的列没有在group by 中出现，那么这个sql就是不合法的。主要原因就是设置的与sql_mode=only_full_group_by不兼容。今天在mysql5.7.x 升级到8.0.x版本的时候 项目接口报错。通过查询发现mysql5.7.5及以上的版本都会依赖检测功能,也就是默认会开启only_full_group_by。8.0.x的版本不支持NO_AUTO_CREATE_USER，去掉即可。

原因 出现此问题的原因是 MySQL 5.7.5 之后默认开启了 ONLY_FULL_GROUP_BY sql_mode。对此官方的解释：MySQL 实现了 函数依赖性 的检测。如果启用了 ONLY_FULL_GROUP_BY SQL模式（默认情况下是这样），MySQL 将拒绝 select list、HAVING condition 或 ORDER BY list 引用的未聚合列，这些列既不在 GROUP BY 子句中命名，也不在功能上依赖于它们。 解决方法 当然，最好的解决方法当然是修改优化 sql 语

报错原因：mysql的5.7以上版本都默认sql_mode=only_full_group_by，这个规则实际是为了提升查询的性能，因此规定我们在查询的时候只能准确的查找要查的唯一数据，不支持group by的分组条件与select的条件不一致。只能写 select id from tableA group id having id='*6*';这种语句，可以在having中控制模糊匹配，但是查询条件和分组条件必须一致。永久性解决该问题，只需要修改mysql的配置文件，my.cnf文件，添加一行配置。
