That would depend on if your cursor is really a cursor or only a "filtered view" of the original table. How was the cursor created? If it's with a SQL SELECT, be sure to add the NOFILTER clause. And no, the original cursor would not be closed, just the alias that you specified. You can even close the original cursor and the new alias will still be around and accessable!
