[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2826) IS [NOT] NULL checks with component values

IS [NOT] NULL checks with component values ------------------------------------------ Key: HHH-2826 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2826 Project: Hibernate Core Issue Type: Improvement Components: query-hql Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.2.6, 3.3.0.CR1 Currently the HQL translator attempts to render IS NULL and IS NOT NULL checks against a component using tuple syntax. Would be much better to instead "explode" these. For example, consider Person with a name property which is a component type of Name and the HQL: "from Person p where p.name is null" Currently, we'd end up with SQL like: "... from person p where (p.f_name, p.l_name) is null" but the exploded form would make much more sense here: "... from person p where ( p.f_name is null and p.l_name is null )"
