最好的办法是“ 为Drop生成脚本 ”
选择数据库 -> 右键单击 -> 任务 -> 生成脚本 -将打开用于生成脚本的向导
在“设置脚本”选项中选择对象后,单击“ 高级”按钮
默认情况下,它包括依赖对象(并且将首先删除约束)
执行脚本
这样我们可以自定义脚本。
删除所有表:
exec sp_MSforeachtable 'DROP TABLE ?'
当然,这将删除所有约束,触发器等,除了存储过程之外的所有内容。
恐怕对于存储过程,您将需要在中存储另一个存储过程master
。
我会在两个声明中这样做: DROP DATABASE ???
我在这里尝试了一些脚本,但是它们对我不起作用,因为我的表具有模式。因此,我整理了以下内容。请注意,此脚本采用模式列表,然后按顺序删除。您需要确保在架构中有完整的顺序。如果存在任何循环依赖关系,则它将失败。

备份一个完全空的数据库。无需删除所有对象,只需还原备份即可。
我今晚不小心对我的master数据库运行了db init脚本。无论如何,我很快就遇到了这个问题。我使用了:exec sp_MSforeachtable'DROP TABLE?' 答案,但是必须执行多次,直到它没有出错(依赖关系。)之后,我偶然发现了其他一些线程,并将其拼凑在一起以删除所有存储过程和函数。

你必须禁用所有triggers
和constraints
第一。
EXEC sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"
EXEC sp_MSforeachtable @command1="ALTER TABLE ? DISABLE TRIGGER ALL"
之后,您可以生成用于删除对象的脚本,如下所示:
SELECT 'Drop Table '+name FROM sys.tables WHERE type='U';
SELECT 'Drop Procedure '+name FROM sys.procedures WHERE type='P';
执行生成的语句。
在这里,我找到了删除所有sp,函数和触发器的新查询
declare @procName varchar(500)
declare cur cursor
for select [name] from sys.objects where type = 'p'

fetch next from cur into @procName

EXEC (@SQL)
PRINT 'Dropped Type: ' + @name
SELECT @name = (select TOP 1 [name] from sys.types where is_user_defined = 1)
END

DECLARE @name VARCHAR(255)
DECLARE @type VARCHAR(10)
DECLARE @prefix VARCHAR(255)
DECLARE @sql VARCHAR(255)
DECLARE curs CURSOR FOR
SELECT [name], xtype

WHERE xtype IN ('U', 'P', 'FN', 'IF', 'TF', 'V', 'TR') -- Configuration point 1
ORDER BY name
OPEN curs
FETCH NEXT FROM curs INTO @name, @type
WHILE @@FETCH_STATUS = 0
BEGIN

SET @prefix = CASE @type
WHEN 'U' THEN 'DROP TABLE'
WHEN 'P' THEN 'DROP PROCEDURE'
