java - HQL language how to join query two tables like in code -


i have 3 tables:
manager
companymanager
company
one many

i need managers without company, in java code can explain:

list<long> managerswithcompany = (list<long>) session.createquery("select distinct mc.idmanager managerscompany mc").list(); list<long> allmanagers = (list<long>) session.createquery("select m.id manager m").

//for example in managerswithcompany have ids: 2 3 4
//for example in allmanagers have ids: 1 2 3 4 5
so, how create query, give me 1 5?
again, need managers have not company
code on java, need query without code, know? 

        arraylist<long> answer = new arraylist<>();         allmanagers.foreach(actman -> {         boolean add = true;         (long allmanager : managerswithcompany ) {               if (actman.equals(allmanager)) {                   add = false;                  break;              }            }            if (add) answer.add(actman);         });

using sql:

select m.id manager m not exists (select * managerscompany mc                   m.id = mc.idmanager)
