[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3500) Hibernate fails to resolve the correct orderby column in SQL when using inheritance hierarchy

Hibernate fails to resolve the correct orderby column in SQL when using inheritance hierarchy --------------------------------------------------------------------------------------------- Key: HHH-3500 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3500 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.0.GA Environment: Derby 10.4.2.0 (http://db.apache.org) Reporter: Joonas Koivunen Original Estimate: 2 days Remaining Estimate: 2 days I have an inheritance hierarchy: @Entity("abstractBaseClass") AbstractBaseClass - ConcreteClass1 - ConcreteClass2 - ConcreteClass3 AbstractBaseClass has: - @Id long id; - String name; @Entity("concreteClass1") ConcreteClass1 has a @OneToMany(mappedBy="concreteClass1") List<ConcreteClass2> @Entity("concreteClass2") ConcreteClass2 has a @OneToMany(mappedBy="concreteClass2") List<ConcreteClass3> and a reference to @ManyToOne ConcreteClass1. @Entity("concreteClass3") ConcreteClass3 has a reference to @ManyToOne ConcreteClass2. After adding a @OrderBy("name") annotation to the getter "List<ConcreteClass3> ConcreteClass2.getConcreteClass3s()" and afterwards accessing the association through an ConcreteClass2 instance I get: SELECT cc3_concrete.cc2_id, cc3_concrete.id, cc3_base.name, cc3_concrete.cc2_id AS cc2_id_2 FROM cc3 cc3_concrete INNER JOIN abstractBaseClass cc3_base ON cc3_concrete.id = cc3_base.id WHERE cc3_concrete.cc2_id = ? ORDER BY abstractBaseClass.name asc (I edited hibernate's naming of entities in SQL to be a bit more clearer). Ordering by "abstractBaseClass.name" causes the problem here; it's obvious that it should had been "cc3_base.name" but for some reason hib just uses the entityname.column_name in the SQL. Another strange thing is that the foreign key column "cc2_id" is being included twice in the results? It is included in the select wheter or not @OrderBy exists. Inheritance strategy used is javax.persistence.InheritanceType.JOINED.
