in OQL, or JQL, how do you do this type of outerjoin

Question

Say we have two completely unrelated entities EntityX and EntityY both with column age. How do I in OQL do a join like so

select x,y from EntityX as x full outer join EntityY as y on x.age = y.age

Is this not possible?

thanks, Dean

Answer 1

full outer join should almost never be used. You should use left outer join instead which is supported by JP-QL/OQL : http://docs.jboss.org/hibernate/entitymanager/3.5/reference/en/html/queryhql.html#queryhql-joins
