i want to know the id value of a foreign key column on an entity without having to load the other entity. any way other than entity.getDependentEntity().getId()? no point going to the db for that.

I was under the impression that calling getId() (or whatever you've called the id in your mapping) does not de-proxy an object. You can call that method and it doesn't go to the DB.

You can also do this in HQL, using the special "id" member of mapped entites: see section 14.8 of the ref docs.
