SQL & PL/SQL :: Identify / Count Records In Ref Cursor Without Actually Fetching?

/* Formatted on 22/01/2013 19:32:50 */
CREATE OR REPLACE PROCEDURE test_rdm_miles (
p_ref_cursor OUT SYS_REFCURSOR
p_success NUMBER)
IS
BEGIN
OPEN p_ref_cursor FOR
SELECT 5168 mem_uid,

[code]....

I have a Procedure with out parameters as a REF CURSOR and response message as p_success.This ref cursor will be returned to the calling service. Is there a way in oracle by which we can identify whether the Ref cursor holds data without actually fetching it. Since if i choose to fetch the data, i will lose one row when i return the ref cursor back to the calling service Or else is there way i can retrieve the row i lose during fetch.

Other alternative what have been suggested is create an object type ,fetch the ref cursor values in object type. Then i can use the ref cursor to return the data by table casting.

one more solution is

OPEN
FETCH
CLOSE
OPEN (AGAIN) { this will lead to redundancy)
