How do I left join tables in unidirectional many-to-one in Hibernate?

I'm piggy-backing off of How to join tables in unidirectional many-to-one condition?. If you have two classes: ``` class A { @Id public Long id; } class B { @Id public Long id; @ManyToOne @JoinColumn(name = "parent_id", referencedColumnName = "id") public A parent; } ``` B -> A is a many to one relationship. I understand that I could add a Collection of Bs to A however I do not want that association. So my actual question is, Is there an HQL or Criteria way of creating the SQL query: ``` select * from A left join B on (b.parent_id = a.id) ``` This will retrieve all A records with a Cartesian product of each B record that references A and will include A records that have no B referencing them. If you use: ``` from A a, B b where b.a = a ``` then it is an inner join and you do not receive the A records that do not have a B referencing them. I have not found a good way of doing this without two queries so anything less than that would be great. Thanks.
