快速删除DiscuzNT论坛数据表和存储过程

桑吉

本来想一个一个删除的，打开数据库一看那么多的表和存储过程，就放弃这种笨办法了，于是决定用SQL语句来搞定。代码如下： 

复制代码

代码如下:

-----------------------------删除数据表--------------------- 
DECLARE @au_lname VARCHAR(40),@SQLString NVARCHAR(500) 
DECLARE tb CURSOR FOR 
SELECT name FROM sysobjects WHERE xtype='U' and name like 'dnt%' 
OPEN tb 
-- Perform the FIRST FETCH. 
FETCH NEXT FROM tb INTO @au_lname 
-- CHECK @@FETCH_STATUS TO see IF there ARE ANY more ROWS TO FETCH. 
WHILE @@FETCH_STATUS = 0 
BEGIN 
-- This IS executed AS long AS the previous FETCH succeeds. 
FETCH NEXT FROM tb INTO @au_lname 
SET @SQLString='DROP TABLE '+ @au_lname 
EXEC sp_executesql @SQLString 
--DROP TABLE @au_lname 
END 
CLOSE tb 
DEALLOCATE tb 
GO
