Left outer join on a unidirectional many to one mapping [message #518116]

I have a many to one relationship from object A to object B.

When I use a bidirectional mapping I can executed the following JPQL query:

SELECT b, a FROM B b LEFT OUTER JOIN b.a a

How can I achieve the same result if I have a unidirectional mapping?

I know it can be done in SQL but I would like to implement it in JPQL.

Thanks,
Andreas
