SQL Server視圖會產生不同的結果集

Question

我有一個SQL Server視圖：

SELECT SOPOrderReturn.DocumentNo, 
     StockItem.Code, 
     SLCustomerAccount.CustomerAccountNumber, 
     SOPOrderReturn.CustomerID, 
     SOPDocDelAddress.PostalName, 
     SOPDocDelAddress.AddressLine1, 
     SOPDocDelAddress.AddressLine2, 
     SOPDocDelAddress.AddressLine3, 
     SOPDocDelAddress.AddressLine4, 
     SOPDocDelAddress.PostCode, 
     SOPOrderReturnLine.LineQuantity, 
     SOPOrderReturn.PromisedDeliveryDate, 
     StockItem.SpareNumber2, 
     StockItem.SpareNumber3, 
     StockItem.Name, 
     StockItem.SpareText2, 
     StockItem.SpareText1, 
     StockItem.SpareNumber1 
FROM SOPOrderReturn 
     INNER JOIN SOPOrderReturnLine 
      ON SOPOrderReturn.SOPOrderReturnID = SOPOrderReturnLine.SOPOrderReturnID 
     INNER JOIN SOPDocDelAddress 
      ON SOPOrderReturn.SOPOrderReturnID = SOPDocDelAddress.SOPOrderReturnID 
     INNER JOIN SLCustomerAccount 
      ON SOPOrderReturn.CustomerID = SLCustomerAccount.SLCustomerAccountID 
     INNER JOIN StockItem 
      ON SOPOrderReturnLine.ItemCode = StockItem.Code 
WHERE (NOT (StockItem.Code LIKE '%DELIVERY%')) AND 
     (NOT (StockItem.Name LIKE '%DELIVERY%')) AND 
     (SOPOrderReturn.PromisedDeliveryDate > CURRENT_TIMESTAMP - 3) 

當所謂的 '是' 從.NET使用此查詢：

SELECT [DocumentNo],[Code], 
     [CustomerAccountNumber], 
     [CustomerID],[PostalName], 
     [AddressLine1],[AddressLine2], 
     [AddressLine3],[AddressLine4], 
     [PostCode],[LineQuantity], 
     [PromisedDeliveryDate], 
     [SpareNumber2], 
     [SpareNumber3], 
     [Name], 
     [SpareText2], 
     [SpareText1], 
     [SpareNumber1] 
FROM [viwSalesOrdersRecent]; 

...一切都虎背熊腰，腳蹬多莉。它返回我期望看到的所有861行，這與SQL Server在視圖中應該顯示的內容相匹配。

然而，當我調用View（如上）與以下WHERE子句上漲了它：不要

WHERE [DocumentNo] = @prmSalesOrderNumber AND [Code] = @prmStockCode; 

查詢返回的整個數據集，忽略了視圖內現有Where子句，我不理解這種行爲。我不熟悉SQL Server，3年沒有觸及過它，現在我已經深入瞭解它，完全超出了我的深度。

任何幫助將不勝感激。

Answer 1

校驗碼最後，我從來沒有解決了這個，所以我最終夾緊它向微軟爲他們看看。

他們已經初步確認這是由SQL Server中的一個錯誤引起的，他們希望在將來的更新中補救錯誤。

Answer 2

我建議你在視圖中添加isnull以及在視圖上查詢。空值在很大程度上影響結果集。下面

 SELECT SOPOrderReturn.DocumentNo, 
       StockItem.Code, 
       SLCustomerAccount.CustomerAccountNumber, 
       SOPOrderReturn.CustomerID, 
       SOPDocDelAddress.PostalName, 
       SOPDocDelAddress.AddressLine1, 
       SOPDocDelAddress.AddressLine2, 
       SOPDocDelAddress.AddressLine3, 
       SOPDocDelAddress.AddressLine4, 
       SOPDocDelAddress.PostCode, 
       SOPOrderReturnLine.LineQuantity, 
       SOPOrderReturn.PromisedDeliveryDate, 
       StockItem.SpareNumber2, 
       StockItem.SpareNumber3, 
       StockItem.Name, 
       StockItem.SpareText2, 
       StockItem.SpareText1, 
       StockItem.SpareNumber1 
     FROM SOPOrderReturn 
       INNER JOIN SOPOrderReturnLine 
        ON SOPOrderReturn.SOPOrderReturnID = SOPOrderReturnLine.SOPOrderReturnID 
       INNER JOIN SOPDocDelAddress 
        ON SOPOrderReturn.SOPOrderReturnID = SOPDocDelAddress.SOPOrderReturnID 
       INNER JOIN SLCustomerAccount 
        ON SOPOrderReturn.CustomerID = SLCustomerAccount.SLCustomerAccountID 
       INNER JOIN StockItem 
        ON SOPOrderReturnLine.ItemCode = StockItem.Code 
     WHERE (NOT (isnull(StockItem.Code,'') LIKE '%DELIVERY%')) AND 
       (NOT (isnull(StockItem.Name,'') LIKE '%DELIVERY%')) AND 
       (SOPOrderReturn.PromisedDeliveryDate > CURRENT_TIMESTAMP - 3) 



     SELECT [DocumentNo],[Code], 
       [CustomerAccountNumber], 
       [CustomerID],[PostalName], 
       [AddressLine1],[AddressLine2], 
       [AddressLine3],[AddressLine4], 
       [PostCode],[LineQuantity], 
       [PromisedDeliveryDate], 
       [SpareNumber2], 
       [SpareNumber3], 
       [Name], 
       [SpareText2], 
       [SpareText1], 
       [SpareNumber1] 
     FROM [viwSalesOrdersRecent] 
     WHERE isnull([DocumentNo],'') = isnull(@prmSalesOrderNumber,'') 
     AND isnull([Code],'') = isnull(@prmStockCode,'')
