我有一张主表人

人字段：Id，AlterationDate

一对多关联中的操作表操作

操作字段：Id，PeopleID，CreationDate

我想查找人中的所有记录，其更改日期晚于人员ID加入的操作中的最新创建日期。

MySQL是方言，日期是DateTime字段。

select people.* from people  
join actions on actions.peopleID = people.id  
group by people.id

from actions a 
inner join people p on p.peopleid = a.peopleid 
group by p.peopleid 
having max (a.creationdate) < p.alterationdate
