修改存儲過程

使用 Transact-SQL

1.在 “對象資源管理器” 中，連接到 數據庫引擎 的實例，然后展開該實例。

2.展開 “數據庫” ，然后展開過程所屬的數據庫。

3.在 “文件” 菜單上，單擊 “新建查詢” 。

4.復制以下示例並將其粘貼到查詢編輯器中，先創建存儲過程。該過程返回 Adventure Works Cycles 數據庫中所有供應商的名稱、所提供的產品、信用等級以及可用性。

IF OBJECT_ID ( 'Purchasing.uspVendorAllInfo', 'P' ) IS NOT NULL   
    DROP PROCEDURE Purchasing.uspVendorAllInfo;  
GO  
CREATE PROCEDURE Purchasing.uspVendorAllInfo  
WITH EXECUTE AS CALLER  
AS  
    SET NOCOUNT ON;  
    SELECT v.Name AS Vendor, p.Name AS 'Product name',   
      v.CreditRating AS 'Rating',   
      v.ActiveFlag AS Availability  
    FROM Purchasing.Vendor v   
    INNER JOIN Purchasing.ProductVendor pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product p  
      ON pv.ProductID = p.ProductID   
    ORDER BY v.Name ASC;  
GO

之后，執行該存儲過程，效果如下：

5.在 “文件” 菜單上，單擊 “新建查詢” 。

6.修改存儲過程。

ALTER PROCEDURE Purchasing.uspVendorAllInfo  
    @Product varchar(25)   
AS  
    SET NOCOUNT ON;  
    SELECT LEFT(v.Name, 25) AS Vendor, LEFT(p.Name, 25) AS 'Product name',   
    'Rating' = CASE v.CreditRating   
        WHEN 1 THEN 'Superior'  
        WHEN 2 THEN 'Excellent'  
        WHEN 3 THEN 'Above average'  
        WHEN 4 THEN 'Average'  
        WHEN 5 THEN 'Below average'  
        ELSE 'No rating'  
        END  
    , Availability = CASE v.ActiveFlag  
        WHEN 1 THEN 'Yes'  
        ELSE 'No'  
        END  
    FROM Purchasing.Vendor AS v   
    INNER JOIN Purchasing.ProductVendor AS pv  
      ON v.BusinessEntityID = pv.BusinessEntityID   
    INNER JOIN Production.Product AS p   
      ON pv.ProductID = p.ProductID   
    WHERE p.Name LIKE @Product  
    ORDER BY v.Name ASC;  
GO

7.點擊執行，即可以保持修改信息到存儲過程。

8.要運行修改后的存儲過程，可以執行下面所示

EXEC Purchasing.uspVendorAllInfo N'LL Crankarm';  
GO  

執行后，效果
