You have to disable all triggers and constraints first.
After that you can generate the scripts for deleting the objects as
SELECT 'Drop Table '+name FROM sys.tables WHERE type='U';
SELECT 'Drop Procedure '+name FROM sys.procedures WHERE type='P';
Execute the statements generated.

此脚本清除所有视图，SPS，函数PK，FK和表 .
我正在使用Adam Anderson的这个脚本，更新为支持除dbo之外的其他模式中的对象 .
资料来源：http://blog.falafel.com/Blogs/AdamAnderson/09-01-06/T-SQL_Drop_All_Objects_in_a_SQL_Server_Database.aspx
最好的办法是“ Generate scripts for Drop ”
选择 Database - > Right Click - > Tasks - > Generate Scripts - 将打开 wizard 以生成脚本
在set Scripting选项中选择对象后，单击 Advanced Button
默认包含依赖对象 . （并且首先会删除约束）
执行脚本
这样我们就可以自定义脚本了 .
删除所有表格：
当然，这将删除除存储过程之外的所有约束，触发器等 .
对于存储过程，我担心您将需要存储在
master中的另一个存储过程 .我会用两个陈述来做：DROP DATABASE ???
然后CREATE DATABASE ???
备份一个完全空的数据库 . 不要删除所有对象，只需恢复备份即可 .
这是我尝试过的：
它将打印什么输出，只需复制全部并粘贴新查询并按下执行 . 这将删除所有表 .
我在这里尝试了一些脚本，但它们对我不起作用，因为我在模式中有表格 . 所以我把以下内容放在一起 . 请注意，此脚本采用模式列表，然后按顺序删除 . 您需要确保在模式中有完整的排序 . 如果存在任何循环依赖关系，那么它将失败 .
今晚我不小心对我的主数据库运行了一个db init脚本 . 无论如何，我很快就遇到了这个帖子 . 我用过：exec sp_MSforeachtable'DROP TABLE？'回答，但不得不多次执行它，直到它没有错误（依赖关系 . ）之后，我偶然发现了一些其他线程并将它拼凑在一起以删除所有存储过程和函数 .
试试这个
除了@ Ivan的回答，还需要包含所有类型
没有一个声明可用于实现这一目标 .
您当然可以创建一个
stored procedure，您可以使用它来执行这些不同的管理任务 .然后，您可以使用此单个语句执行该过程 .
对我来说似乎是一个相当危险的特征 . 如果你实现这样的东西，我会确保以一种你无法在每次事故中运行它的方式正确保护它 .
如前所述，您可以自己制作某种存储过程 . 在SQL Server 2005中，您可以查看此系统表以确定并找到要删除的对象 .
