Say I have a MyBean "A" that has a PK "guid", and may or not have a parent of the same kind MyBean.
Is there a EJB-QL to find if either "A" or it's parent, or it's parent parent, etc, has a certain primary key?
I tried used a half-baked solution, where I artificially limited the nesting to two levels:
SELECT a.guid from MyBeans as a WHERE a.guid = ?1 OR a.parent.guid = ?1 OR a.parent.parent.guid = ?1
Even this won't work, because if "a" does not have a parent or a grandparent, the SQL query produced will leave it out.
