公司的一个客户要求把DiscuzNT从现有网站删除（数据和页面），页面简单，FTP连接上去删除就可以了，数据表的删除就有点纠结了：我的DNT论坛是和现有的网站系统共用的一个数据库。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：
-----------------------------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
