asp实现的查询某关键词在MSSQL数据库位置的代码
功能是：以一个关键字为索引，搜索整个数据库，然后返回那个关键字所在的表名和列名。（很赞...特别是入侵的时候找不到用户名与密码所在的表的时候，如果能直接通过输入admin这个关键词找出字段...省得一个表一个表的看了。）于是根据那段语句，写了个asp的脚本，方便大家以后搜寻数据库。 代码如下： 复制代码 代码如下: <% 'Confirm a keyword's position of a database(which table & which column) 'By oldjun(http://www.oldjun.com) 'Based on huangzi(http://www.2chuizi.com)'s sql Server.ScriptTimeout=999999999 Response.Buffer =true On Error Resume Next keyword=request("keyword") if keyword="" then response.write "Need keyword!" response.End End if dim conn Set conn = Server.CreateObject("ADODB.Connection") Dim ConnStr 'ConnectionString,Pls change! ConnStr="Driver={SQL SERVER};Server=localhost;UID=sa;PWD=sa;Database=master" Conn.open ConnStr conn.execute("CREATE TABLE huangzi_table(id int identity(1,1),biaoid int,biaoname nvarchar(1000))") conn.execute("insert huangzi_table select [id],[name] from sysobjects where xtype='U'") set rs =conn.execute("select count(id) as tnum from huangzi_table") tnum=rs("tnum") rs.close set rs=nothing for i=1 to tnum set rsbiao =conn.execute("select biaoid from huangzi_table where id="&i&"") biaoid=rsbiao("biaoid") set rst =conn.execute("select [biaoname] from huangzi_table where biaoid="&biaoid&"") tname=rst("biaoname") set rsl=conn.execute("select count([name]) as lnum from syscolumns where id="&biaoid&"") lnum=rsl("lnum") for j=1 to lnum topnum=j-1 set rslie=conn.execute("select top 1 [name] from syscolumns where id="&biaoid&" and [name] not in (select top "&topnum&" [name] from syscolumns where id="&biaoid&")") liename=rslie("name") set rsresult=conn.execute("select top 1 ["&liename&"] from ["&tname&"] where CAST(["&liename&"] AS NVARCHAR(1000))='"&keyword&"'") if rsresult.bof or rsresult.eof then 'response.write "Nothing-"&tname&":"&liename 'response.write "
" else result=rsresult(liename) response.write result&"("&tname&":"&liename&")" response.write "
" End if rslie.close set rslie=nothing rsresult.close set rsresult=nothing next rsbiao.close set rsbiao=nothing rst.close set rst=nothing rsl.close set rsl=nothing next conn.execute("DROP TABLE huangzi_table") %> 注：效率很差，使用时可能出现假死， 请耐心等待，大库还是别用了；代码简单，实现的简单功能，没技术含量，留着以后备用；换连接语句的时候有个缓存问题，建议重启下浏览器！
