I'm wondering if Hibernate can take a ResultSet object and produce an object or list based on a mapping definition?

Not sure if this is what your after but HQL does allow a query to be projected and this then can be stored in a Data object. The result is a List of object from the resultset, eg,

sess.find("select new DataObject(o.field1, o.field2) from o in class DomainObject ");

This is not possible in hibernate but you can do this with SQLJ to some extend.

So this would allow me to limit the fields being pulled from the database in the case of presenting a user with a larger list objects where we only want to show them *10%* of the fields--- in hopes of improving performance?
