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
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.

Joonas Koivunen commented on HHH-3500:
--------------------------------------
Having logging set for "org.hibernate" to DEBUG does not reveal anything useful
on forming the SQL leading to this error. And for all clearness; the exception thrown on
the SQL prepared by hib over here is:
java.sql.SQLSyntaxErrorException: Column 'ABSTRACTBASECLASS.NAME' is either not in
any table in the FROM list or appears within a join specification and is outside the scope
of join ....
I've seen other SQL syntax errors while fiddling around with inheritance hierarchies
but have not remembered to report them as in the end they were a result of very stupid
designing of the relations; however is not a goal to have Hibernate produce always CORRECT
sql and detect errors beforehand?

--------------------------------------
sebersole #hibernate hinted that the org.hibernate.engine.JoinSequence or the persister
could be interesting suspects to look at..
