1.请在sql server 中建一数据库 name:house 在house中运行下列脚本
if exists (select * from sysobjects where id = object_id(N'[dbo].[City]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[City]
GO
if exists (select * from sysobjects where id = object_id(N'[dbo].[Area]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Area]
GO
CREATE TABLE [dbo].[City] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[name] [nvarchar] (10) NULL
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Area] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[CityId] [int] NULL ,
[name] [nvarchar] (20) NULL
) ON [PRIMARY]
GO
INSERT INTO City (id,name) Values(1,"广州")
INSERT INTO City (id,name) Values(2,"上海")
INSERT INTO City (id,name) Values(3,"北京")
INSERT INTO Area (id,CityId,name) Values(1,1,"天河")
INSERT INTO Area (id,CityId,name) Values(2,1,"白云")
INSERT INTO Area (id,CityId,name) Values(3,2,"虹口")
INSERT INTO Area (id,CityId,name) Values(4,2,"宝山")
INSERT INTO Area (id,CityId,name) Values(5,2,"静安")
INSERT INTO Area (id,CityId,name) Values(6,3,"海淀")
INSERT INTO Area (id,CityId,name) Values(7,3,"朝阳")
2.建立文件
建立文件CityData.asp
<%@ LANGUAGE=VBSCRIPT %>
<% RSDispatch %>
<SCRIPT RUNAT=SERVER Language=javascript>
<!--#INCLUDE VIRTUAL="/_ScriptLibrary/RS.ASP"-->
<!--#INCLUDE VIRTUAL="/jsconn.asp"-->
function Description()
{
this.GetAreaAsArray = DoGetData;
}
public_description = new Description();
function DoGetData(cityId)
{
var sql,rst,strText,conn,i,j
conn = new ActiveXObject("ADODB.Connection");
conn.ConnectionString = connstr;
conn.ConnectionTimeout = 30;
conn.Open();
sql = "Select name,id from area where cityid='" + cityId + "'";
rst = new ActiveXObject("ADODB.Recordset");
rst.CursorLocation = 3;
rst.Open(sql,conn);
i = 0;
j = 0;
strText = new Array();
if (rst.RecordCount >= 1)
{
for(var i=0;i<rst.RecordCount;++i)
{
strText[j++] = rst.Fields("name").Value;
strText[j++] = rst.Fields("id").Value;
rst.movenext();
}
}
else
{
strText[j++] = "没有";
strText[j++] = 1;
}
rst.close();
conn.close();
return strText;
}
</SCRIPT>
建立文件jsconn.asp
<SCRIPT RUNAT=SERVER Language=javascript>
var connstr = "driver={SQL Server}; server=202.0.0.108;uid=sa;pwd=;database=house";
</SCRIPT>
建立文件pub.asp

Set conn = Server.CreateObject("ADODB.Connection")
conn.Open connstr
Set Session(SessionName) = conn
End If
Set OpenOrGet_Database = Session(SessionName)
End Function

建立文件sql_pub.asp

建立文件test.asp
