It's been a while so please help me wrap my head around this.

I want to use updateable remote views against a sql backend that has compound integer keys on some of its tables.

In this case I have a remote view that joins Product_in_Future_Change with Product on Product_id.

But Future_change_id and product_id make up a compound key on PFC, which is the table will be updating.

For purposes of pulling data to be updated with this view I want all the records with a FC_id ( ie. for all products )

Of course I will not be changing the prod_id in the record

When I save to the backend from this view, does the sql passthrough that gets sent know I am using the compound key in order to match my record with the record on the backend?

(It would seem they should but in the past I have always been able to design my own schema and I hold as an article of faith that compound keys are almost as evil as non-surrogate keys )

TIA

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
