这个例子中的第一站是ASP页。这个ASP页用ADO与Northwind 数据库连接。为了保持良好的编码习惯,我
使用了Option Explicit 并明确地声明了所有变量。这个ASP页的第一个草稿使用了内联代码。

Dim x
ConnectionString = "DSN=Northwind;"
Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open ConnectionString

'Set variables
oRS.ActiveConnection = oConn
oRS.Source = "Select * from Products"
oRS.Open
