update

Hi,

I need to update a joined sub-class. Since Hibernate doesn't allow to update joined sub-classes in hql or named-query I want to do it via SQL. I also can't use a sql named-query because updates via named-query are not supported in Hibernate.

So I decided to use a SQLQuery. But Hibernate complaints about not calling addScalar().

Are updates returning the number of rows affected and how is named that column?

Are there any other ways to do an update on a joined sub-class in hibernate?

Thanks in advance!
