How to reset a cursor in PL/SQL?

Question

Hi everyone
I have a CURSOR in PL/SQL with a number N of rows. I fetch all these rows in a bucle, but, when the last row is arrived, and the condition NOTFOUND is true, I'd like to return to the first row, and do the same process again. I mean, fetching every row a number of times k. For example, in a cursor of 3 rows:
Row 1
Row 2
Row 3
Row 1
Row 2
... and on
If I close the cursor and then I open it, there is no data, because the cursor is in the last row and the FETCH return NOTFOUND, so I'd like to "reset" the cursor and begin from the first row again.
How could I do this?
Thank you very much and sorry for my english

Hi,
This is not really a question for the APEX forum but with that said...
What defines k?
Your requirement looks a little fraught with danger as you could end up in a tight (endless) loop...
What are you really trying to achieve with this logic?
If you have a maximum number of iterations that you want to loop through then perhaps try declaring an explicit cursor, loop through this cursor inside another (nested) loop.
Eg
DECLARE
l_char table1.col1%TYPE;
cnt PLS_INTEGER := 0;
CURSOR x IS
SELECT col1
FROM table1;
BEGIN
FOR m IN 1..3 LOOP
FOR i IN x LOOP
l_char := i.col1;
cnt := cnt + 1;
dbms_output.put_line(cnt||' '||l_char);
END LOOP;
END LOOP;
END;
