I've been thinking about it this morning... I think that we're going
to have to drop the idea of keeping the cursor open and go with the
idea suggested earlier (sorry, I forget by who) of issuing multiple
SQL statements slightly hacked to limit the row set.
Otherwise it's just not going to fly with multiple statements.
