Right. But since you can't really write a literal SQL statement that does
an update that refers to a previous query, you are already doing a fair
amount of internal magic anyway, so if the meta-data is determined by
magic as well, that seems consistent.
What you need is an updateable cursor on the server side. It has all the
facilities you need, including standardized ways to find out the
updatability metadata. Please concentrate on that and do not attempt to
clutter the wire protocol with data that will not withstand a throrough
investigation of semantics.
