asp实现的查询某关键词在MSSQL数据库位置的代码

作者:袖梨 2023-09-01

整体而言,这段SQL只适宜用在小型数据库上,ASP中的循环也没效率,大库还是别用了,小库可以考虑。如果是大库的话,请联系皇子要另外一份牛人写的SQL查询语句。

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:

<%

'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 "<br>"

else

result=rsresult(liename)

response.write result&"("&tname&":"&liename&")"

response.write "<br>"

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")

%>
