Also of note: Assuming that you want changes propagated through to a base table in a Client/Server application...there is a KB article that describes how to convert a result set (one returned via an SQL Pass-through query) into a read-write cursor such that changes will be propagated back to the base table on the server. It's basically done by using a bunch of cursorsetprop calls.
