昨天 的接受参数 dlid=request.querystring("dlid")
但是如何让他在接受 jieshou.asp?dlid=123 123这个用户ID的同时 检查数据库内是否存在这个 ID呢？

<%else
Set rs = Server.CreateObject("ADODB.Recordset")
sql="select * from [User] where ID=" & session("ID")
rs.open sql,conn,1,3 '后面就不知道了这个是我的数据库
%>

<%else
Set rs = Server.CreateObject("ADODB.Recordset")
sql="select * from [User] where ID=" & session("ID")
rs.open sql,conn,1,3 if rs.recordcount>0 then

response.write("该用户存在")

else

response.write("该用户不存在")

end if
%>
这样就行了吧

谢谢你 阳光白雪 ！！！

怎么出现错误
Microsoft VBScript 编译器错误 (0x800A03EA)
语法错误

大家帮忙检查下错误~！谢谢了

是的 我只摘了有用的代码！
别的估计没什么用，主要是上面的
