java专家可以帮助我编写分离查询作为以下sql语句的条件查询的一部分.
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
解决方法
你需要编写一个
correlated subquery.假设属性/类名与上面的列/表名匹配：
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);
