Answer 1

Try this Answer,

CREATE TABLE #Numbers(N INT)

INSERT INTO #NUMBERS(N)
SELECT TOP 495 ROW_NUMBER() OVER(ORDER BY T1.NUMBER) AS N
FROM   MASTER..spt_values T1 
       CROSS JOIN MASTER..spt_values t2

SELECT N,CASE WHEN LEN(CAST((N+4)/5 as VARCHAR))<2 THEN '0'+CAST((N+4)/5 as VARCHAR) ELSE CAST((N+4)/5 as VARCHAR) END[Loop]
    ,CASE WHEN N%10 in(1,6) THEN 1 WHEN N%10 in(2,7) THEN 2 WHEN N%10 in(3,8) THEN 3 WHEN N%10 in(4,9) THEN 4 WHEN N%10 in(5,0) THEN 5 END q_id 
from #Numbers

UPDATE A SET A.Loop=B.Loop, AND A.q_id=B.q_id
FROM qcard A,#Numbers B
WHERE (A.qcard%10000)=B.N

UPDATE B
SET B.groupcode=A.groupcode
FROM q_id A,qcard B
WHERE A.q_id=B.q_id

DROP TABLE #Numbers
