[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-3749) Only reuse FromElements originating from from-clause if their aliases match

Only reuse FromElements originating from from-clause if their aliases match --------------------------------------------------------------------------- Key: HHH-3749 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3749 Project: Hibernate Core Issue Type: Bug Components: query-hql Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.2.x, 3.3.x Consider: select ( select clasn1.name from riskClasns_Contxt0.clasn as clasn1 ) as policyType from Risk as risk0 inner join risk0.riskClasns_Contxt as riskClasns_Contxt0 inner join riskClasns_Contxt0.clasn as clasn0 inner join clasn0.clasnScheme as clasnScheme0 Currently we miss the conditions needed in the subquery because we reuse the from element corresponding to riskClasns_Contxt0.clasn from the outer query. Again the solution is to recognize that each has a different alias indicating that we should not reuse the FromElement from the outer query here. alias matching here needs to consider null as never matching
