can we use group by clause in cursor

hie, how can we use group by clause in select statement for cursor.

for example
i used

CREATE OR REPLACE PROCEDURE SHOW_ATTENDANCE_RECORD
AS
CURSOR ATT_PEOPLE IS
SELECT c.MID COUNT(c.ATT)
FROM ATTENDANCE c,
WHERE c.ATT = '&ATT'
GROUP BY c.MID
BEGIN
FOR DISPLAY IN ATT_PEOPLE LOOP
DBMS_OUTPUT.PUT_LINE('ID NO:'||display.MID, COUNT(c.ATT));
END LOOP;
END;

how can we show the count in the procedure and use the group by clause in order to do so ..

many thanks
