How to Show only One Credit Column at a time

Question

Hi,
        This is the Query :- it displays  all the credit columns simultaneously
SELECT OINV.DocDate AS 'Posting date',
                      OCRD.GroupNum AS 'Payment Terms', OCRD.Balance AS 'Amount', OINV.DocTotal AS ' Debit Amount',
                      CASE WHEN OCRD.GroupNum = 7 THEN (OINV.DocTotal - OCRD.BALANCE) ELSE 0 END AS 'Credit 7',
                      CASE WHEN OCRD.GroupNum = 9 THEN (OINV.DocTotal - OCRD.BALANCE) ELSE 0 END AS 'Credi 9',
                      CASE WHEN OCRD.GroupNum = 5 THEN (OINV.DocTotal - OCRD.BALANCE) ELSE 0 END AS 'Credi 5',
OINV.DocDueDate AS 'Due date ',OINV.Address
FROM         OCRD INNER JOIN
                      OINV ON OINV.CardCode = OCRD.CardCode
WHERE (OINV.DocDate  BETWEEN '04/08/11' AND '06/09/11'  AND OINV.CardCode = 'C00356')
- it displays  all the credit columns simultaneously
i want if GroupNum =7 then ,it should display the data in Credit 7 Column and rest Credit 5 and Credit 9 should be hide (Credit 5 and Credit 9 columns should not be shown in the data)
Similarly, if GroupNum =5 then, it should display the data is Credit 5 Column and rest Credit 7 and Credit 9 should be hide
similarly for GroupNum =9.
Kindly give me the solution for this problem.

Hi Rahul.....
Try this.....
SELECT OINV.DocDate AS 'Posting date',
OCRD.GroupNum AS 'Payment Terms', OCRD.Balance AS 'Amount', OINV.DocTotal AS ' Debit Amount',
(Case When OCRD.GroupNum=7 Then (OINV.DocTotal - OCRD.BALANCE)
Else
Case When OCRD.GroupNum=9 Then (OINV.DocTotal - OCRD.BALANCE)
Else
Case When OCRD.GroupNum=5 Then (OINV.DocTotal - OCRD.BALANCE)
Else 0
End End End) As 'Credit',
OINV.DocDueDate AS 'Due date ',OINV.Address
FROM OCRD INNER JOIN
OINV ON OINV.CardCode = OCRD.CardCode
WHERE (OINV.DocDate BETWEEN '04/08/11' AND '06/09/11' AND OINV.CardCode = 'C00356')
