求解：如何根据字段的值，显示出不同的内容
表 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"-->
