Condition variable for sql query

Question

I have created the follwing query which adds the open sales orders and forecasts to create a projected cashflow.  The query works fine except I would like to be able to enter the forecast code, rather than have it hard coded.  If I enter Where OFCT.code='[%0]', I get no results for the forecast. 
SELECT     FCT1.ItemCode "Item", FCT1.Date "Date", FCT1.Quantity "Qty", ITM1.Price "Price", (FCT1.Quantity*ITM1.Price)"Ext Price"
FROM         OFCT INNER JOIN
                      FCT1 ON OFCT.AbsID = FCT1.AbsID INNER JOIN
                      ITM1 ON FCT1.ItemCode = ITM1.ItemCode
WHERE     (ITM1.PriceList = '2') AND (OFCT.Code ='5/24/2010')
UNION
SELECT          RDR1.ItemCode "Item", RDR1.ShipDate "Date", RDR1.Quantity "Qty", RDR1.Price "Price", (RDR1.Quantity*RDR1.Price)"Ext Price"
FROM          RDR1
WHERE          RDR1.LineStatus = 'O' and  RDR1.OpenQty >'0'
ORDER BY DATE

Answer 1

Try this:
Declare @fcod char(16)
set @fcod/* select f.code from ofct f where f.code*/='[%0]'
SELECT FCT1.ItemCode "Item", FCT1.Date "Date", FCT1.Quantity "Qty",
ITM1.Price "Price", (FCT1.Quantity*ITM1.Price)"Ext Price"
FROM OFCT INNER JOIN
FCT1 ON OFCT.AbsID = FCT1.AbsID INNER JOIN
ITM1 ON FCT1.ItemCode = ITM1.ItemCode
WHERE (ITM1.PriceList = '2') --AND (OFCT.Code =@fcod)
UNION
SELECT RDR1.ItemCode "Item", RDR1.ShipDate "Date", RDR1.Quantity "Qty",
RDR1.Price "Price", (RDR1.Quantity*RDR1.Price)"Ext Price"
FROM RDR1
WHERE RDR1.LineStatus = 'O' and RDR1.OpenQty >'0'
ORDER BY DATE
