Hello guy's having a bit of a problem writing a subselect query with criteria API sublselect should take a parameter from selected q
SELECT c.file_id as fid, s.person as person, s.fax_no as fax, s.phone_no as phone,(SELECT SUM( b.ammount )
FROM billing b
WHERE b.constants_file_id = c.file_id
) - (
SELECT
CASE
WHEN b.partioa_pay IS NULL
THEN "0"
ELSE SUM( b.partioa_pay )
END
FROM billing b
WHERE b.constants_file_id = c.file_id ) AS totalout
FROM constants c
LEFT JOIN firm_management s ON c.firm_management_firm_managment_id = s.firm_managment_id
WHERE s.firm_managment_id = ?
As you can see the totalout suselected against c.file_id I was playing with this for 2 days with no luck maby sombody in stackoverflow community who has a strong java and hibernate knowledge would be able to help me.. This is what I got getting exeption 2012-01-17 01:48:06,808 ERROR [org.hibernate.util.JDBCExceptionReporter] - (session F2C61D08758E0AA09CA6C99A5B6F2145, thread 113 invoke ByDefenceFirm.getByDefenceFirm)
Criteria crit = session.createCriteria(Constants.class, "co");
crit.createAlias("co.provider", "pr", Criteria.INNER_JOIN)
.createAlias("co.firmManagement", "ins", Criteria.LEFT_JOIN)
.createAlias("co.law", "lw", Criteria.LEFT_JOIN)
.createAlias("co.billing", "bl", Criteria.LEFT_JOIN)
.setProjection(Projections.projectionList()
.add(Projections.property("co.fileId"))
.add(Projections.property("co.status"))
.add(Projections.property("co.asi"))
.add(Projections.property("pr.name"))
.add(Projections.property("ins.companyName"))
.add(Projections.property("lw.shortName")));
DetachedCriteria valueCrit = DetachedCriteria.forClass(Billing.class, "bl")
.setProjection(Projections.sum("bl.ammount"))
.setProjection(Projections.property("bl.constants"))
.add(Restrictions.eqProperty("bl.constants", "co.fileId"));
crit.add(Property.forName("co.fileId").eq(valueCrit));
crit.setProjection(Projections.property("co.billing"));
crit.add(Restrictions.eq("lw.lawOfficeId", prid));
resultList = crit.list();
If anybody have any suggestions would really appreciated it.
A subselect in the select clause is impossible with Criteria. You'll have to go with a HQL or a SQL query.
It is possible. At least now with the current version of Hibernate. Use "Restrictions.sqlRestriction()".
For example:
Criteria accountCriteria = getCurrentSession().createCriteria(Account.class);
accountCriteria.add(Restrictions.sqlRestriction("{alias}.field IN (SELECT ......)"));
@SuppressWarnings("unchecked")
List<Account> accounts = accountCriteria.list();
Sorry, I didn't read the question carefully. Your scenario is different.
