[Hibernate] updating half an entity with HibernateTemplate

[marta]

Hi, I´m using Spring 3.0.5 and Hibernate 3 in my project, updating my entities with HibernateTemplate:

getHibernateTemplate().saveOrUpdate(myEntityVO);

But for updating just some columns of my database I need to do it with HQL with:
getHibernateTemplate().bulkUpdate(query);
otherwise the values of myEntityVO that I don't want to update are overwritten to NULL.

Does anybody know a way to avoid HQL for this kind of update, using for example, Criteria?

Thank you in advanced.

e = getHIbernateTemplate().getSession().get(YourEntity.class, yourEntity.getId());
e.setOne(yourEntity.getOne());
e.setTwo(yourEntity.getTwo());
