node to traverse cannot be null (Hibernate SQL)

Question

I\'m performing a SQL query through hibernate, which looks like:

SELECT thi 
FROM track_history_items thi 
JOIN artists art 
  ON thi.artist_id = art.id 
WHERE t         


        

Answer 1

I have gotten that error only when using createQuery instead of createNamedQuery. So when detecting this, hibernate throws the exception.

Query query = entityManager.createQuery("DS.findUser");
