--------------------------------------
Another vote from me!
No idea why this is "Minor" - it was a show stopper for us because we have quite
a few casts in our queries.
As a workaround be "pimped" our Dialect to effectively do the same as the patch
does - not beautiful, but it works - perhaps it helps someone:
{code:java}
@Override
public String getCastTypeName(final int code)
{
final String caller = new Throwable().getStackTrace()[1].getClassName();
if
(caller.startsWith("org.hibernate.ejb.criteria.CriteriaQueryCompiler"))
{
return getHibernateTypeName(code);
}
else
{
return super.getCastTypeName(code);
}
}
{code}
javax.persistence.criteria.Expression.as() is broken
----------------------------------------------------
Key: HHH-5755
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5755
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.6.0
Reporter: Artem Troitskiy
Priority: Minor
Attachments: HHH-5755.patch
When I try to execute criteria query containing typecast to {{String}}
{noformat}
CriteriaQuery<Product> criteria = builder.createQuery( Product.class );
Root<Product> from = criteria.from( Product.class );
criteria.where(builder.like(from.get("partNumber").as(String.class),
"1%"));
List<Product> result = em.createQuery( criteria ).getResultList();
{noformat}
I get the following exception
{quote}
org.hibernate.hql.ast.QuerySyntaxException: expecting CLOSE, found '(' near line
1, column 132 [select generatedAlias0 from org.hibernate.ejb.metamodel.Product as
generatedAlias0 where cast(generatedAlias0.partNumber as varchar(255)) like :param0]
{quote}
As you can see, SQL type is used in HQL {{cast}} clause. It's caused by
{{CriteriaQueryCompiler.RenderingContext.getCastType()}} that erroneously return SQL
typename instead of Hibernate typename.
