关于删除SQL Server一些对象的SQL语句

在我们学习工作生活，可能需要将数据对象批量的删除；

以下SQL语句，可能会帮到我们，在SQL Server 2000/2005 测试通过；

declare @objname as varchar(100)
declare @subobject as varchar(100)
declare @sql as varchar(300)

--delete all constraints or foreign keys
while exists (select a.[name] as tablename ,b.[name] as objname 
			  from sysobjects a,(select [name],parent_obj from sysobjects where [type]='D' or [type]= 'F') b
			  where a.id = b.parent_obj)
begin
select top 1 @objname  = a.[name] ,@subobject = b.[name]
			  from sysobjects a,(select [name],parent_obj from sysobjects where [type]='D' or [type]= 'F') b
			  where a.id = b.parent_obj
select @sql = 'alter table ' + @objname + ' drop constraint ' + @subobject
exec(@sql) 
end 

--delete all views 
while exists (select * from sysobjects where [type]='V' and id > 0)
begin
select top 1 @objname = [name] from sysobjects where [type]='V' and id > 0
select @sql = 'drop view ' + @objname
exec(@sql)
end 

--delete all procedures
while exists (select * from sysobjects where [type]='P' and id >0)
begin
select top 1 @objname = [name] from sysobjects where [type]='P' and id >0
select @sql = 'drop proc ' + @objname
exec(@sql)
end 


--delete all tables
while exists (select * from sysobjects where [type]='U')
begin
select top 1 @objname = [name] from sysobjects where [type]='U'
select @sql = 'drop table ' + @objname
exec(@sql)
end
