Java – hibernate separates queries as part of conditional queries

Java experts can help me write separate queries as part of the conditional queries in the following SQL statements

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

Solution

You need to write a correlated subquery Assume that the attribute / class name matches the column / table name above:

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);
