Hibernate - second level association
Let's say I have table foo, table bar, and table zoo. foo has a member bar and there is a one to one relationship between them. bar has a list and there is a one to many relationship between them.
the list is not initialized automatically when bar is read (ie it is lazy) Using hql I would like to get a list of the foo objects with zoo initialized in bar.
so something on the lines of:
select f from Foo f
left join fetch f.bar.zoo
this obviously throws an exception and I get that it's because the owner being returned i开发者_运维问答s Foo and not Bar. Nonetheless I need Foo and not Bar and I need zoo to be initialized. Is there a way to do this in one query?
Thanks Jill
The following should work:
FROM Foo f
LEFT JOIN FETCH f.bar b
LEFT JOIN FETCH b.zoos
