I have two Objects: Country & Site

The database contains all the world's countries. A Site object refer to one and only country.

I want to retrieve the list of Country objects that has a Site attached to them. So exclude all others countries that are not "used" by a site.

How can I achieve that with the nHibernate Criterias API ?

Thanks in advance.

Maybe something like

Code:

ICriteria crit = session.CreateCriteria(typeof(Country));
critQuery.Add(Expression.IsNotEmpty("Site"));
