求解:如何根据字段的值,显示出不同的内容
  data 里面有个字段是N_Fname   ,这个字段里 有些有值的,有些是没有值的

我想显示 所有N_Fname  字段是空的信息  大家看看下面的代码 怎么改一下!

下面代码执行是没有错误的,但显示的是全部的信息!!在哪个地方改一下,只显示所有N_Fname  字段是空的信息




<!--#include file="include/Conn.asp"-->
<!--#include file="include/char.asp" -->
<!--#include file="Include/setup.asp"-->
<!--#include file="Include/check_admin.asp"-->
