如何獲得從屬視圖在SQL Server中自動更新？

Question

我們公司的某個人決定使用3個視圖來支持一個網頁，他們必須包含一些相同的列。所以我的定義是這樣的：

CREATE VIEW EmailReceivedView 
AS 
SELECT  
    dbo.EmailReceived.ID 
    , ...lots of columns 
FROM dbo.EmailReceived 
LEFT OUTER JOIN ...more tables 

--Emails related to reviews 
CREATE VIEW ReviewEmailReceivedView 
AS 
SELECT RV.ReviewID, V.* 
FROM ReviewEmailReceived RV 
INNER JOIN EmailReceivedView V ON EmailReceivedID = V.ID 

--Emails related to reviews 
CREATE VIEW GrantEmailReceivedView 
AS 
SELECT GV.GrantID, V.* 
FROM GrantEmailReceived GV 
INNER JOIN EmailReceivedView V ON GV.EmailReceivedID = V.ID 

現在我做了五*在相關視圖的原因是在事件的支持觀點的變化，我想相關視圖以反映更改。但是，除非我將腳本作爲ALTER腳本重新運行，否則SQL Server中不會發生這種情況。爲什麼不？有沒有辦法確保對支持視圖的更改會自動反映到依賴關係中？

還有sp_refreshsqlmodule我只是喜歡，因爲你也可以用它對於不是意見模塊。要實現這樣的刷新所有視圖的腳本，不過，你可以這樣做：

DECLARE @sql NVARCHAR(MAX); 
SET @sql = N''; 

SELECT @sql = @sql + N' 
    EXEC sys.sp_refreshsqlmodule 'N'' 
    + QUOTENAME(s.name) + N'.' 
    + QUOTENAME(v.name) + N''';' 
FROM sys.views AS v 
INNER JOIN sys.schemas AS s 
ON v.[schema_id] = s.[schema_id] 
WHERE v.is_ms_shipped = 0 
-- AND v.name LIKE '%EmailReceivedView%' 
; 

PRINT @sql; 
-- EXEC sys.sp_executesql @sql; 

但更重要的是，這是正是爲什麼you shouldn't use SELECT * in a view。

sp_refreshview：

sp_refreshview [ @viewname = ] 'viewname' 

SQL Server – refresh all Views
