"is empty" with inner join generates invalid sql select and invalid results --------------------------------------------------------------------------- Key: HHH-4794 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4794 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.2 Environment: Hibernate version as provided with Netbeans 6.8 (Hibernate EntityManager 3.3.2.GA, Hibernate Annotations 3.3.1.GA) DBMS: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production; With the OLAP and Data Mining options Reporter: Ramon Casha Attachments: testcase.zip Given two simple entities, Master and Detail which have a OneToMany relationship: The following JPQL query... Select T from Master T, in(T.details) D where D is empty generates the following SQL: [1] select master0_.id as id0_ [2] from Master master0_ [3] inner join Detail details1_ on master0_.id=details1_.master_id [4] where not (exists (select details1_.id from Detail details1_)); Line 4 is incorrect! The alias created there (details1_) is DIFFERENT from details1_ on line 3, so the subquery runs over the entire table, not the inner-joined table in line 3.
