How to use hibernate criteria to return only one element of an object instead the entire object?

Question

I\'m trying to get only the list of id of object bob for example instead of the list of bob. It\'s ok with a HQL request, but I would know if it\'s possible using criteria ?

Answer 1

Similarly you can also:

Criteria criteria = session.createCriteria(bob.class);

criteria.add(Expression.gt("id", 10));

criteria.setProjection(Projections.property("id"));

criteria.addOrder(Order.asc("id"));

return criteria.list();
