I have a select like this:

DECLARE @NoClient Int
DECLARE @Tax Float
DECLARE @NoStatus Int
DECLARE @NoStatus2 Int
DECLARE @AddDate DateTime

SET @NoClient=2087603
SET @Tax=1
SET @NoStatus=7
SET @NoStatus2=8
SET @AddDate='2014-10-01 15:29:59'

SELECT Invoice.Numero
 FROM Invoice (NOLOCK)
 WHERE Invoice.NoClient=@NoClient AND Invoice.Tax=@Tax AND
  Invoice.NoStatus<>@NoStatus AND Invoice.NoStatus<>@NoStatus2 AND
  Invoice.AddDate>@AddDate

From IIS and ASP.NET, this returns 0 record. From SSMS, it returns 1 record.

Can someone tell me what could be a setting factor here that could make IIS and ASP.NET not able to find the record?
