如果由於外鍵約束刪除table失敗,則先刪除所有約束:
--/第1步**********刪除所有表的外鍵約束*************************/
DECLARE c1 cursor for
select 'alter table ['+ object_name(parent_obj) + '] drop constraint ['+name+']; '
from sysobjects
where xtype = 'F'
open c1
declare @c1 varchar(8000)
fetch next from c1 into @c1
while(@@fetch_status=0)
begin
exec(@c1)
fetch next from c1 into @c1
end
close c1
deallocate c1
--/第2步**********刪除所有表*************************/
use 數據庫
declare @tname varchar(8000)
set @tname=''
select @tname=@tname + Name + ',' from sysobjects where xtype='U'
select @tname='drop table ' + left(@tname,len(@tname)-1)
exec(@tname)
刪除所有的存儲過程同理可得,但不需要走第一步,只需將第2步的代碼的where xtype='U' 改成 where xtype='P',drop table 改成 drop Procedure
