有没有人会有一个脚本会丢弃SQL Server数据库中的所有对象？

我目前无权在服务器上删除和创建数据库，因此我正在寻找一个脚本将我带回'方形'

我在网上看过一些，但是他们没有按照正确的顺序做事，或者他们没有删除所有内容。

如果使用模式，您可能会发现以下脚本非常有用：

DECLARE @OnlyInSchema sysname;
-- Set this to a value to only drop objects in one schema.
-- SET @OnlyInSchema = N'';

DECLARE @Commands TABLE (
    [Description]   NVARCHAR(MAX),
    [Line]          NVARCHAR(MAX)
);

DECLARE @Drops TABLE (
    [Type]          NVARCHAR(2),
    [Template]      NVARCHAR(MAX)

我在“http://kashyapmakadia.blogspot.com/2009/08/drop-everything-in-sql-server-2005.html”上找到了这段代码，并尝试了它，它只是找到了!!你可以在那里找到代码，但如果你赶时间，代码是：

您可以尝试使用开源bsn ModuleStore versioning toolkit，它可以创建数据库清单，并为尊重对象依赖关系的数据库模式创建DROP脚本。它目前支持表，索引，触发器，视图，函数，存储过程和XML模式集合。

using (ManagementConnectionProvider provider = new ManagementConnectionProvider(connection, "dbo")) {
    DatabaseInventory inventory = new DatabaseInventory(provider, "dbo");
    string dropScript = string.Join(";\r\nGO\r\n\r\n", inventory.GenerateUninstallSql().ToArray());
}

Select * From sysobjects Where....

然后逐一放下。
