Hello,

I have an object A mapping to object B with many-to-one relationship. In the database schema table A has a B_ID column for this purpose. So normally if I want to get the ID of a B from A I'd do a.getB().getID().

The question is: for performance reason, can I get B_ID from A without first instantiating the B object? The only way I can think of doing this right now is map the B_ID column to both a bID field and a B object. But is there a better way of doing this?

Thanks!
