快速刪除DiscuzNT論壇數據表和存儲過程

本來想一個一個刪除的，打開數據庫一看那么多的表和存儲過程，就放棄這種笨辦法了，于是決定用SQL語句來搞定。代碼如下：

-----------------------------刪除數據表---------------------

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
