在这里我找到了新的查询删除所有sp，函数和触发器

declare @procName varchar(500)
declare cur cursor 

for select [name] from sys.objects where type = 'p'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec('drop procedure ' + @procName)
    fetch next from cur into @procName
end
close cur
deallocate cur

最好的方法是“为Drop生成脚本”

选择数据库->右键单击->任务->生成脚本-将打开生成脚本的向导

在set Scripting选项中选择对象后，单击高级按钮

设置选项“Script to create”为true(想要创建) 设置选项“Script to Drop”为true(想要删除) ->选中复选框，选择要创建脚本的对象 ->选择写脚本的选项(文件，新建窗口，剪贴板) 默认情况下，它包含依赖对象。(并将首先删除约束) 执行脚本

这样我们就可以自定义脚本。

DECLARE @name VARCHAR(255)
DECLARE @type VARCHAR(10)
DECLARE @prefix VARCHAR(255)
DECLARE @sql VARCHAR(255)

DECLARE curs CURSOR FOR
SELECT [name], xtype
FROM sysobjects
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
-- Configuration point 2
SET @prefix = CASE @type
WHEN 'U' THEN 'DROP TABLE'
WHEN 'P' THEN 'DROP PROCEDURE'
WHEN 'FN' THEN 'DROP FUNCTION'
WHEN 'IF' THEN 'DROP FUNCTION'
WHEN 'TF' THEN 'DROP FUNCTION'
WHEN 'V' THEN 'DROP VIEW'
WHEN 'TR' THEN 'DROP TRIGGER'
END

SET @sql = @prefix + ' ' + @name
PRINT @sql
EXEC(@sql)
FETCH NEXT FROM curs INTO @name, @type
END

CLOSE curs
DEALLOCATE curs

备份一个完全空的数据库。不需要删除所有对象，只需恢复备份。

在我看来这是一个相当危险的功能。如果你要实现这样的东西，我会确保以一种你不能每次事故都运行它的方式正确地保护它。

如前所述，您可以自己创建某种存储过程。 在SQL Server 2005中，您可以查看这个系统表来确定和查找您想要删除的对象。

select * from sys.objects

这个脚本清除所有视图，SPS，函数pk, fk和表。
