Sorry in advance if I misunderstand you, but a high isolation level
and a dynamic cursor are incompatible with each other. You cannot be
both isolated and aware of every update that's going on at the same
time. So you cannot just let the user enable snapshot isolation if you
want to implement a dynamic cursor.
