How to get distinct results in hibernate with joins and row-based limiting (paging)

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

criteria.setProjection(Projections.distinct(Projections.id()));

DetachedCriteria idsOnlyCriteria = DetachedCriteria.forClass(MyClass.class);
//add other joins and query params here
idsOnlyCriteria.setProjection(Projections.distinct(Projections.id()));

Criteria criteria = getSession().createCriteria(myClass);
criteria.add(Subqueries.propertyIn("id", idsOnlyCriteria));
criteria.setFirstResult(0).setMaxResults(50);
return criteria.list();
