[Hibernate-JIRA] Created: (HHH-2831) Native SQL queries with addJoin or <return-join/> return object arrays instead of single Entities
by Jeremy Grodberg (JIRA)
Native SQL queries with addJoin or <return-join/> return object arrays instead of single Entities
-------------------------------------------------------------------------------------------------
Key: HHH-2831
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2831
Project: Hibernate3
Issue Type: Bug
Components: query-sql
Affects Versions: 3.2.5, 3.2.4
Environment: Hibernate 3.2.4.ga and 3.2.5.ga with hsqldb on Win XP
Reporter: Jeremy Grodberg
Attachments: NativeSQLQueriesTest.patch
Although the documentation is not crystal clear, I read it to say that using addJoin should eagerly fetch an associated object but should NOT return it as a separate value. In section 16.1.3. "Handling associations and collections" of the online documentation it says: "It is possible to eagerly join in the Dog to avoid the possible extra roundtrip for initializing the proxy. This is done via the addJoin() method, which allows you to join in an association or collection." This comes BEFORE the section on returning multiple entities, so I say the documentation at least implies it will only return a single entity at the top level. Also, if the intention is to return multiple entities, addEntity() works fine for that, so what then would be the difference of addJoin()? If I'm wrong about what addJoin() should do, please clarify that in the documentation and also clarify how, if it is possible, one could eagerly fetch the association without changing the return type of the quer
y.
I have reproduced this problem in the Hibernate JUnit tests in 3.2.4.ga and 3.2.5.ga, specifically NativeSQLQueriesTest.testSQLQueryInterface().
I'm attaching a patch to the Hibernate junit test org.hibernate.test.sql.hand.query.NativeSQLQueriesTest.java released in 3.2.5.ga that adds a test to ensure that a query with addJoin only returns a (list of) entities, not a list of Object arrays containing entities. Currently, the assertion fails because instead of returning a list of Organizations we get a list of Object[3] = { Organization, Employment, Person }, which is exactly what we get when the addJoin()s are replaced with appropriate addEntity() calls.

[Hibernate-JIRA] Created: (BVAL-198) Simplify creation of ConstraintViolationExceptions
by Gunnar Morling (JIRA)
Simplify creation of ConstraintViolationExceptions
--------------------------------------------------
Key: BVAL-198
URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-198
Project: Bean Validation
Issue Type: Improvement
Components: spec-general
Affects Versions: 1.1
Reporter: Gunnar Morling
javax.validation.ConstraintViolationException wraps a set of constraint violations, currently in the following form:
Set<ConstraintViolation<?>> constraintViolations
As the exception's constructors have a parameter of the same type, instantiating it is not as easy as expected:
Validator validator = ...;
DomainObject domainObject = new DomainObject();
Set<ConstraintViolation<DomainObject>> constraintViolations = validator.validate(domainObject);
//compiler error: ("The constructor ConstraintViolationException(Set<ConstraintViolation<DomainObject>>) is undefined")
throw new ConstraintViolationException(constraintViolations);
//this works
throw new ConstraintViolationException(new HashSet<ConstraintViolation<?>>(constraintViolations));
This problem can be solved by changing the collection type to
Set<? extends ConstraintViolation<?>>
The exception then would read as follows:
public class ConstraintViolationException extends ValidationException {
private final Set<? extends ConstraintViolation<?>> constraintViolations;
public ConstraintViolationException(String message, Set<? extends ConstraintViolation<?>> constraintViolations) {
super( message );
this.constraintViolations = constraintViolations;
}
public ConstraintViolationException(Set<? extends ConstraintViolation<?>> constraintViolations) {
super();
this.constraintViolations = constraintViolations;
}
public Set<ConstraintViolation<?>> getConstraintViolations() {
return new HashSet<ConstraintViolation<?>>(constraintViolations);
}
}
This makes the exception easier to use for producers, while maintaining simplicity for clients (since getConstraintViolations() still returns a Set<ConstraintViolation<?>>, clients don't have to do deal with the bound wildcard expression).

[Hibernate-JIRA] Created: (HHH-3298) Hibernate does not correcly apply LockMode.UPGRADE when performing a polymorphic select to a leaf-class via a mapped superclass on Oracle
by Mike Everett (JIRA)
Hibernate does not correcly apply LockMode.UPGRADE when performing a polymorphic select to a leaf-class via a mapped superclass on Oracle
-----------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-3298
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3298
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6, Oracle 10gR2
Reporter: Mike Everett
Attachments: src.zip
Greetings All,
I'm experiencing an issue with Hibernate generated SQL when I attempt to retrieve a union-subclass entity via a concrete mapped superclass with LockMode.UPGRADE.
Hibernate will generate SQL with a UNION ALL of the sub-classes and then apply FOR UPDATE to the query which is not allowed with Oracle.
This leads to the following error:
java.sql.SQLException: ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.
It seems that "etc." part includes UNION and UNION ALL.
Example with three classes:
Entity (abstract) <--extends--- ConcreteInheritorOne (concrete) <--extends-- ConcreteInheritorTwo (concrete)
assume:
inheritorTwoId == the id of an item of class ConcreteInheritorTwo
session == a Hibernate Session
// These lookups will cause the error
Entity e = (Entity) session.get(Entity.class, inheritorTwoId, LockMode.UPGRADE);
Entity e = (Entity) session.get(ConcreteInheritorOne.class, inheritorTwoId, LockMode.UPGRADE);
// This will not cause the error
Entity e = (Entity) session.get(ConcreteInheritorTwo.class, inheritorTwoId, LockMode.UPGRADE);
I have attached entity classes and a Test class which illustrate this effect.
I spelunked into the code a bit, but an easy fix did not present itself to my hibernate-code-virgin eyes.
Thanks for making Hibernate great!
--Mje
#### Workaround ####
If anyone else is experiencing this problem, I've implemented code similar to the method below as a work-around in an abstraction layer:
public Object getEntityForUpdate(Class entityClass, String entityId)
{
Session s = getSession();
ClassMetadata meta = s.getSessionFactory().getClassMetadata(entityClass);
Boolean doTwoPhaseLock = false;
if(meta instanceof UnionSubclassEntityPersister)
{
if(((UnionSubclassEntityPersister)meta).getEntityMetamodel().getSubclassEntityNames().size() > 1)
doTwoPhaseLock = true;
}
if(doTwoPhaseLock)
{
Entity e = (Entity)s.get(entityClass, entityId);
System.out.println("Using Two-Phase Lock on: EntityId[" + entityId + "] EntityClass[" + entityClass.getName() + "]");
s.lock(e, LockMode.UPGRADE);
return e;
}
else
{
System.out.println("Using One-Phase Lock on: EntityId[" + entityId + "] EntityClass[" + entityClass.getName() + "]");
return s.get(entityClass, entityId, LockMode.UPGRADE);
}
}
#### Hibernate Generated SQL Example ####
select
entity0_.id as id6_0_,
entity0_.versionNumber as versionN2_6_0_,
entity0_.clazz_ as clazz_0_
from
(
select versionNumber, id, 2 as clazz_
from BASE_ConcreteInheritorTwo
union all
select versionNumber, id, 1 as clazz_
from BASE_ConcreteInheritorOne
) entity0_ where entity0_.id=?
for update
