Hibernate 3.0.5

How do i pass partition keys to related methods. I have BUSINESS_ID on all my tables and i partition my oracle database based on business_id column.

In most of my queries I pass the BUSINESS_ID as my parameter but if an object has a relationship with some other object say a User Object has a 1-->n relationship with a Role object and I call user.getRoles the query generated will have the the appropriate foreign key column but additionally the query needs to add the BUSINESS_ID column.

How do i achieve this?

Thanks
