hi try answer query undertood
1. criteria can select projections, or root entity.
2. below code snippet should work retrieve students result "pass".(i assume store value in result when student passes subject)

criteria criteria = session.createcriteria(student.class, "student"); criteria.createalias("student.subject", "subject "); criteria.add(restrictions.eq("subject.result", "pass"); criteria.setresulttransformer(criteriaspecification.distinct_root_entity); 

3. hql better , simpler you, try below hql ..
   again making assumption 'pass' result.
   

   select distinct student student student join student.subject subject subject.result = 'pass'
