Query for item warehouses stock in a row

Question

hi all,
How to retreive item warehouse stock in a row using query ?
SELECT T0.ItemCode, T1.ItemName, T2.ItmsGrpNam,
(Select WhsCode from OITW Where
WhsCode=T0.WhsCode and ItemCode=T0.ItemCode) as 'Wh',
(Select OnHand From OITW Where
Whscode = T0.WhsCode and Itemcode=T0.ItemCode) as 'Whstck'
FROM OITW T0  INNER JOIN OITM T1 ON T0.ItemCode = T1.ItemCode INNER JOIN OITB T2 ON T1.ItmsGrpCod = T2.ItmsGrpCod
WHERE T0.ItemCode NOT IN 'a-item'AND
T2.ItmsGrpNam LIKE '%%test%%'
and T0.Onhand > 0
ORDER BY T0.ItemCode
Anyone correct query so that it will retrieve item warehouse stock in a single row.
Thanks

I have tested your query, the result is just like you wish. The code can be simplified to:
SELECT T0.ItemCode, T1.ItemName, T2.ItmsGrpNam, T0.WhsCode as 'Wh',T0.OnHand as 'Whstck'
FROM DBO.OITW T0 
INNER JOIN DBO.OITM T1 ON T0.ItemCode = T1.ItemCode
INNER JOIN DBO.OITB T2 ON T1.ItmsGrpCod = T2.ItmsGrpCod
WHERE T0.ItemCode NOT IN ('a-item') AND T2.ItmsGrpNam LIKE '%[%test%]%'
and T0.Onhand > 0
ORDER BY T0.ItemCode, T0.WhsCode
If you want each item has only one row and warehouse on hand column-wised, you have to use as much as SELECT for each column in according to your number of warehouses. It would be look like this one:
SELECT T0.ItemCode, T0.ItemName, T1.ItmsGrpNam,
(SELECT OnHand FROM OITW WHERE ItemCode = T0.ItemCode AND WhsCode Like 'Whs1') AS 'Whs1 On Hand' ,
(SELECT OnHand FROM OITW WHERE ItemCode = T0.ItemCode AND WhsCode Like 'Whs2') AS 'Whs2 On Hand' ,
(SELECT OnHand FROM OITW WHERE ItemCode = T0.ItemCode AND WhsCode Like 'Whs3') AS 'Whs3 On Hand'
FROM DBO.OITM T0 
INNER JOIN DBO.OITB T1 ON T1.ItmsGrpCod = T0.ItmsGrpCod
WHERE T0.ItemCode NOT IN ('a-item') AND T1.ItmsGrpNam LIKE '%[%test%]%'
and T0.Onhand > 0
ORDER BY T0.ItemCode
