Problem with "not" function of CriteriaBuilder ---------------------------------------------- Key: HHH-5736 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5736 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.6.0 Reporter: Vyacheslav Dimitrov Let us suppose that we have entity "Floor" with property of "number". Then we want to create query with the help of Criteria API: we want to get all floors and exclude floors with number of 2 and 3. Let us suppose that our code is: CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery<Tuple> cr = builder.createTupleQuery(); Root<Floor> root = cr.from(Floor.class); cr.multiselect(root); Predicate p1 = builder.equal(root.get("number"), new Integer(2)); Predicate p2 = builder.equal(root.get("number"), new Integer(3)); cr.where(builder.not(builder.or(p1, p2))); So we get query: [java] Hibernate: [java] select [java] floor0_.beanId as beanId0_, [java] floor0_.building_beanId as building3_1_, [java] floor0_.number as number1_ [java] from [java] Floor floor0_ [java] where [java] floor0_.number=2 [java] or floor0_.number=3 This query is wrong. Function "not" doesn't work. But for query "get all floors and exlclude floor with number 2" this code works: CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery<Tuple> cr = builder.createTupleQuery(); Root<ru.petrsu.nest.son.Floor> root = cr.from(ru.petrsu.nest.son.Floor.class); cr.multiselect(root); Predicate p = builder.equal(root.get("number"), new Integer(2)); cr.where(builder.not(p)); We get correct query: [java] Hibernate: [java] select [java] floor0_.beanId as beanId0_, [java] floor0_.building_beanId as building3_1_, [java] floor0_.number as number1_ [java] from [java] Floor floor0_ [java] where [java] floor0_.number<>3 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
