How To Call A Procedure While Declaring A Cursor

HI,
WHILE DECLARING A CURSOR TO SELECT RECORDS FROM A TABLE WE NORMALLY WRITE :-

DECLARE CUR_NAME CURSOR
FOR SELECT * FROM CLEANCUSTOMER

BUT SAY, IF I HAVE WRITTEN A SIMPLE PROCEDURE CALLED AS MY_PROC :-

CREATE PROCEDURE MY_PROC
AS
SELECT A.INTCUSTOMERID,A.CHREMAIL,B.INTPREFERENCEID,C.CHR PREFERENCEDESC
FROM CLEANCUSTOMER A
INNER JOIN TRCUSTOMERPREFERENCE03JULY B
ON A.INTCUSTOMERID = B.INTCUSTOMERID
INNER JOIN TMPREFERENCE C
ON B.INTPREFERENCEID = C.INTPREFERENCEID
ORDER BY B.INTPREFERENCEID

WHICH IS RUNNING FINE AND GIVING ME THE REQUIRED DATA WHILE EXECUTING THE PROCEDURE :-

EXEC MY_PROC

BUT IF I WANT TO CALL THIS PROCEDURE MY_PROC WHILE DECLARING A CURSOR :-

I AM USING :-

DECLARE CHK_CUR CURSOR
FOR SELECT * FROM MY_PROC

WHICH IS GIVING AN ERROR "Invalid object name 'MY_PROC'."


AND IF I USE :-

DECLARE CHK_CUR CURSOR
FOR EXEC MY_PROC

WHICH IS GIVING AN ERROR "Incorrect syntax near the keyword 'EXEC'".


AND IF I USE :-

DECLARE CHK_CUR CURSOR
FOR CALL MY_PROC

WHICH IS GIVING AN ERROR "Incorrect syntax near 'CALL'. "

IS THERE ANY WAY BY WHICH I CAN FETCH RECORDS FROM THE STORED PROCEDURE?
HOW DO I DECLARE THE PROCEDURE WHILE WRITING THE CURSOR
PLS HELP.

I NEED THIS URGENTLY, I HAVE TO USE THE CURSOR TO FETCH THE RECORDS FROM THE SP,THAT'S HOW THEY WANT IT.I CAN'T HELP IT AND I DON'T KNOW HOW

THANKS
