来源：百度文库 编辑：高校问答 时间：2024/05/03 22:46:39
CourseN: C_ID C_Name
Course: CourseID CourseName CourseTime CoursePlace CourseLeft
-------------------------------
代码如下,想在2级列表中选择CourseName和CourseTime后显示Course表中所关联的CoursePlace 和CourseLeft的值,求具体实现方法,谁能帮下忙,谢谢了
代码如下
<%@LANGUAGE="VBSCRIPT"%>
<!--#include file="../Connections/ConSelCourse.asp" -->

Dim Recordset1
Dim Recordset1_numRows
Set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_ConSelCourse_STRING
Recordset1.Source = "SELECT * FROM CourseN"
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 1
Recordset1.Open()
Recordset1_numRows = 0

dim id
id=request.QueryString("id")
if id="1" then
response.Write "<br>" & request.Form("lstb")
response.Write "<br>" & request.Form("lsts")
