Hibernate分离查询作为条件查询的一部分

Question

Java专家能否请您帮我写以下查询作为SQL查询条件查询的一部分。

select A.*
FROM AETABLE A
where not exists
(
    select entryid
    FROM AETABLE B
    where B.classpk = A.classpk
    and B.userid = A.userid
    and B.modifiedDate > A.modifiedDate
)
and userid = 10146

Answer 1

您需要编写一个相关的子查询。假设属性/类名称与上面的列/表名称匹配：

DetachedCriteria subquery = DetachedCriteria.forClass(AETable.class, "b")
 .add(Property.forName("b.classpk").eqProperty("a.classpk"))
 .add(Property.forName("b.userid").eqProperty("a.userid"))
 .add(Property.forName("b.modifiedDate").gtProperty("a.modifiedDate"));

Criteria criteria = session.createCriteria(AETable.class, "a")
 .add(Property.forName("userid").eq(new Integer(10146)))
 .add(Subqueries.notExists(subquery);
