Passing Variable Values Into A Nested SQL In An OLEDB Datasource

All:
I am trying to code the following SQL into an OLEDB data source but it is not allowing me to do so because I think the variables are nested in multiple SQL statements. I have seen other posts that suggest using a variable to store the SQL but I am not sure how it will work.

I would also like to mention that the OLEDB source executes from within a For Each loop that is actually passing the values for the variables, which was one of the reasons I got stumped on how I could have a variable store the SQL.

Here is the SQL:


select b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor,sum(a.Ordered) As Qty_Pruchased
From SXE..POLine a INNER JOIN
(SELECT VIR_Program.ProgramID, VIR_ActiveSKU.ProductCode, VIR_ActiveSKU.BuyerID, Vendor
FROM VIR_Program INNER JOIN
VIR_ActiveSKU ON VIR_Program.ProgramID = VIR_ActiveSKU.ProgramID
INNER JOIN Vendor ON VIR_Program.VendorID = Vendor.VendorID
WHERE ProgramFreq=?) b
ON a.ProductCode = b.ProductCode
WHERE a.TransDate >=? AND
a.TransDate ?
Group By b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor

Thanks!
