Multi join SQL querry are not correctly produced ------------------------------------------------ Key: HHH-890 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-890 Project: Hibernate Core Issue Type: Bug Components: core Reporter: Misko Hevery I would like to produce a query such as this.... SELECT c.ID as componentID FROM GEN_COMPONENT as c INNER JOIN GEN_COMPONENT_VALUE v0 ON c.ID=v0.component_id INNER JOIN GEN_COMPONENT_VALUE v1 ON c.ID=v1.component_id WHERE componentKind_id IN (?,?) AND v0.property_id=? AND v0.val=? AND v1.property_id=? AND v1.val=? I would expect that this code would produce the above SQL. (pseudo-code) Criteria comp = session.createCriteria(Component.class, "c"); Criteria v1 = comp.createCriteria(Component.PROP_VALUES, "v1"); Criteria v2 = comp.createCriteria(Component.PROP_VALUES, "v2"); v1.add(Restrictions.eq("property_id", p1); v1.add(Restrictions.eq("val", 60); v2.add(Restrictions.eq("property_id", p2); v2.add(Restrictions.eq("val", 50)); I have tried many different combinations but i either get a runtime exception or this incorect SQL SELECT c.ID as componentID FROM GEN_COMPONENT as c INNER JOIN GEN_COMPONENT_VALUE v ON c.ID=v.component_id WHERE componentKind_id IN (?,?) AND v.property_id=? AND v.val=? AND v.property_id=? AND v.val=? In either case it is not what I want. As far as I can tell this is not possible... But I might be wrong...
