It looks like you aren't implementing the cursor correctly. A cursor should go and get the entire result set that you would like to work on and then you rifle through it.
select all I need
while (there is a current record) do
begin trans update it commit end trans
done
Instead of reselecting everytime, the result set is available and you operate until you have nothing left in your result set.
