HQL通过连接两个表来选择一个实体的属性

Question

我有两张桌子

first table (people):id ,name;
second table (relation):id,parent_id,child_id

第二个表包含第一个表中对象之间的父链接。很简单））

通过这个查询，我得到了两个表中的所有字段

from People AS people , Relation  as relation WHERE  relation.parent_id=XXX AND people.id=relation.child_id

如何从第一张表中获取字段？

Answer 1

select people from People AS people , Relation  as relation WHERE  relation.parent_id=XXX AND people.id=relation.child_id
