在我正在處理的MVC Web應用程序中,我有4個特定的表,這些表使用並自動生成角色身份驗證。在創建遷移併爲我的數據庫創建種子後,我運行創建這4個表的應用程序。在VS2012中創建存儲過程以一次刪除4個表格?
每當我必須修改我的模型時,由於用戶表上的引用約束,我不得不刪除這4個表。 VS2012不允許我一次選擇所有4個表並刪除,所以我想知道是否有一種方法可以創建一個存儲過程,我可以執行4個刪除腳本一次運行嗎?
根據Server Explorer
我右鍵單擊Stored Prcoedures
,然後選擇Add New Stored Procedure
。我則提出了以下模板:
CREATE PROCEDURE [dbo].[Procedure]
@param1 int = 0,
@param2 int
AS
SELECT @param1, @param2
RETURN 0
通過當我點擊DELETE
爲每個表的我抄在下面自動生成的DROP TABLE命令的GUI。
如何在VS2012中創建一個存儲過程(或多個?),以便在一個命令中刪除所有4個表?

我對存儲過程沒有太多的經驗,任何幫助或輸入表示讚賞。簡單地嘗試讓重複性任務更容易一點。
