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

Another option (though a bit un hibernate-esque) is to use "raw" sql, like this:

List myList = session.createSQLQuery("select single_column from table_name")
          .addScalar("single_column", StandardBasicTypes.LONG).list();
