And that subsequent reading of results may be interleaved. What it doesn't do is allow a single query to return multiple results sets in an interleaved order. What I'm trying to say is that the client can't read the results of a function in any other order than it calls RETURN NEXT. OTOH, if the server returns a cursor handle, the client can read the cursors in any order it chooses. Is this clear, or am I just confusing people (including possibly myself)?
