删除SQL DB中的所有对象？

Question

是否有人有脚本将所有对象拖放到SQL Server DB中？

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来将我带回“方形”

我已经在网上看到了一些内容，但是他们没有以正确的顺序进行操作，或者没有删除所有内容。

如果使用架构，则可能会发现以下脚本有用：

SET NOCOUNT ON;

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)
);

CLOSE CommandCursor;
DEALLOCATE CommandCursor;

您可以尝试开源bsn ModuleStore 版本控制工具包，它可以创建数据库清单，并为尊重对象依赖性的数据库模式创建 DROP 脚本。目前它支持表、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());
}
