Hello everyone,

Let's say I have 2 object: Company and Contact. Contact has
attribute 'company' of type Company as a look up value.
(in database it's two table 'companies' and 'contacts' where
the latter has foreign key to the former)

Now I need to show list of contacts with company name for
each contact. In repository.xml class-descriptor for Contact
has reference-descriptor pointing to Company (typical 1:1
mapping). When contact list gets displayed with 10 rows,
OJB (PB) executes 11 queries: 1 - to get contact and then 10
to get Company info for every contact.

11 queries with this simple case (in real situation it's much more)
is just not acceptable. 

Is there a way for OJB to issue only one query to get all information?

Any hint is greatly appreciated!

Yuriy Zubarev
