使用ASP实现网站的目录树
本来想多翻译些东西出来的,但是最近越来越忙了,以后我尽量多贴些
短小的代码出来,翻译是越来越没空完成了。呵呵。
数据库结构(共使用了两个表)
1。tblCategory
字段名  类型   
Root   binary   说明树关或开(目录的根)
ID     自动编号 关键字
Sort   integer  识别该字段内容的整数(如果root是开状态sort为0)表示显示的目录的顺序
Name   text(255)可以包含html中的标识符
HREF   text(255) 允许空
2。tblPages
ID   自动编号
Sort  integer 关键字
Name  text(255)
HREF  text(255)
