of eager fetch in JPQL as follows: SELECT c FROM C JOIN FETCH c.bList WHERE c.id=:id But when I attempt to take it to the 2nd level: SELECT c FROM C JOIN FETCH c.bList JOIN FETCH c.bList.aList WHERE c.id ... : SELECT c FROM C JOIN c.bList b JOIN FETCH c.bList JOIN FETCH b.aList WHERE c.id=:id but that gets

the WHERE clause. Try LEFT OUTER JOIN : SELECT a FROM A a LEFT JOIN a.another b WHERE a.another IS NULL OR b ... query: SELECT a FROM A a JOIN a.another b WHERE a.another IS NULL OR b.counter = 0 You missed the A instance with no another because navigation through a relationship is implemented using JOIN (i.e
