Question

我有一个SQL Server视图：

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)

使用此查询从.net调用'原样'时：

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

......一切都很笨拙。它返回我希望看到的所有861行，这与SQL Server在View中应该说的相匹配。

但是，当我调用View（如上所述）并在其上添加以下Where子句时：

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

查询返回整个数据集，忽略View中现有的Where子句，我不明白这种行为。我已经没有使用SQL Server了，已经3年没碰过它了，而且我现在已经回到了它的深处并完全脱离了我的深度。

非常感谢任何帮助。

最终我从来没有解决过这个问题，所以我最终把它放到了微软，让他们看看。

他们暂时确认这是由SQL Server中的错误引起的，他们希望通过将来的更新来解决这个问题。

我建议您在视图中添加isnull以及在视图中查询。空值会在很大程度上影响结果集。检查以下代码

        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,'')

SQL Server视图生成不同的结果集
