  通过以上的代码即可显示表的结构,字段类型,长度,自动编号,主健。如果你仔细研究后就可以发现如何远程改变数据库的结构了,祝你好运!

要查看此演示,需要你建立一个数据源,request("table")改为你的表的名字。
<html>
<head>
<title>main</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

<p>

on error resume next
table=request("table")
//获得表名
if table<>"" then
response.write "数据表:"&table
Set primary = con.OpenSchema(adSchemaPrimaryKeys, _
Array(empty, empty, table))
if primary("COLUMN_NAME")<>"" then
primarykey=primary("COLUMN_NAME")
end if
primary.close
set primary=nothing
