you have to define the PK field and source table. In fact it does not matter how the view got its contents. If you're writing data, if is checking if a records was update, deleted or inserted and uses the PK field and table settings in the view definition to cascade it to the underlying tables.

IOW, there is not neccesarely a direct relation between the SQL statement and the table which gets updated.
