【问题描述】：
在我正在处理的 MVC Web 应用程序中，我有 4 个用于角色身份验证并自动生成的特定表。在创建迁移并为我的数据库播种后，我运行创建这 4 个表的应用程序。
每当我必须修改我的模型时，由于我的用户表上的引用约束，我不得不删除这 4 个表。 VS2012 不允许我一次选择所有 4 个表并删除，所以我想知道是否有办法让我创建一个存储过程，我可以执行让 4 个 Drop Scripts 一次运行？
在Server Explorer 下，我右键单击Stored Prcoedures，然后选择Add New Stored Procedure。然后我会看到以下模板：
CREATE PROCEDURE [dbo].[Procedure]
@param1 int = 0,
@param2 int
AS
SELECT @param1, @param2
RETURN 0
当我为每个表单击DELETE 时，我通过 GUI 复制了以下自动生成的 DROP Table 命令。
如何在 VS2012 中创建一个存储过程（或多个？）以在一个命令中删除所有 4 个表？

我在存储过程方面没有太多经验，感谢任何帮助或输入。只是试图让重复的任务变得更容易一些。
