Question : Help filtering on derived column

I have the following query which returns a rows that contain a date and an amount.  I tried to modify the WHERE clause to return only a single row for a specific date.  The query executes but no data is returned.  Can someone clue me into the problem?

SELECT     CONVERT(varchar, DATEADD(d, tblPaymentTerms.LateAfterDays, tblInvoice.DateSubmitted), 111) AS DueDate, SUM(COALESCE (details.SubTotal, 0)
                      - COALESCE (payments.Total, 0) + COALESCE (tblInvoice.Shipping, 0)) AS BalanceDue
FROM         tblPaymentTerms INNER JOIN
                      tblInvoice ON tblPaymentTerms.ID = tblInvoice.fkPaymentTerms LEFT OUTER JOIN
                          (SELECT     fkInvoice, SUM(Amount) AS Total
                            FROM          tblInvoicePayment
                            GROUP BY fkInvoice) AS payments ON payments.fkInvoice = tblInvoice.ID LEFT OUTER JOIN
                          (SELECT     d.fkInvoice, SUM((d.Quantity * d.UnitPrice) * (1 + CASE d .Taxable WHEN 1 THEN i.SalesTaxRate ELSE 0 END)) AS SubTotal
                            FROM          tblInvoiceDetail AS d INNER JOIN
                                                   tblInvoice AS i ON i.ID = d.fkInvoice
                            GROUP BY d.fkInvoice) AS details ON details.fkInvoice = tblInvoice.ID
WHERE     (tblInvoice.fkInvoiceStatus IN (2, 3, 4, 5, 6, 7))
GROUP BY CONVERT(varchar, DATEADD(d, tblPaymentTerms.LateAfterDays, tblInvoice.DateSubmitted), 111)
ORDER BY duedate

If I change the WHERE clause to the following I have no rows returned even though there is valid data.

WHERE     (tblInvoice.fkInvoiceStatus IN (2, 3, 4, 5, 6, 7)) AND (CONVERT(varchar, DATEADD(d, tblPaymentTerms.LateAfterDays, tblInvoice.DateSubmitted), 111)  = '06/01/2010')

Answer : Help filtering on derived column

The derived actually results in YYYY/MM/DD Format ..so change your Where clause to

(CONVERT(varchar, DATEADD(d, tblPaymentTerms.LateAfterDays, tblInvoice.DateSubmitted), 111)  = '2010/06/01')

Check these date formats

SELECT CONVERT(VARCHAR,GETDATE(),101) -- MM/DD/YYYY
SELECT CONVERT(VARCHAR,GETDATE(),111) -- YYYY/MM/DD
