Friends,

Please find my sample table below

table1
-------

PurchaseId | Gross | Deduction | Amount
101 | 1000 | 25 | 975
102 | 2000 | 75 | 1925

table2
-------
PurchaseId | Item | Qty | Price | Amount
101 | A | 2 | 20 | 40
101 | B | 1 | 60 | 60
101 | CXYZ | 1 | 900 | 900
102 | B | 1 | 2000 | 2000

CXYZ is always a special Item.

My Expected output

Where PurchaseId = 101

PurchaseID | Gross | Deduction | SpecialAmount
101 | 1000 | 25 | 900

Where PurchaseId = 102

PurchaseID | Gross | Deduction | SpecialAmount
102 | 2000 | 75 | 0

Thanks in advance.

[code]SELECT t1.PurchaseID,
t1.Gross,
t1.Deduction,
COALESCE(t2.Amount,0) AS SpecialAmount
FROM table1 t1
LEFT JOIN table2 t2
ON t2.PurchaseId = t1.PurchaseId
AND t2.Item = 'CXYZ'
[/code]
