ASP分页显示Recordset数据

9/17/2008来源:ASP技巧人气:12474

1.建立Recordset对象

Dim objMyRst

Set objMyRst=Server.CreateObject(“ADODB.Recordset”)

objMyRst.CursorLocation=adUseClientBatch ‘客户端可批量处理

objMyRst.CursorType=adOpenStatic’光标类型为静态类型

注意:Recordset对象不能用Set objMyRst=Connection.Excute strSQL的语句建立,因为其建立的Recordset对象为adOpenFowardOnly不支持记录集分页

2.打开Recordset对象

Dim strSql

strSql=”select * from ietable”

objMyRst.Oepn strSql,ActiveConnection,,,adCmdText

3.设置Recordset的PageSize属性

objMyRst.PageSize=20

默认的PageSize为10

4.设置Recordset的AbsolutePage属性

Dim intCurrentPage

intCurrentPage=1

objMyRst.AbsolutePage=intCurrentPage

AbsolutePage为1到Recordset对象的PageCount值

5.显示数据

Response.Write("<table>")

PRintFieldName(objMyRst)

For i=1 To objMyRst.PageSize

PrintFieldValue(objMyRst)

objMyRst.MoveNext

If objMyRst.Eof Then Exit For

Next

Response.Write("</table>")

说明:

1. adOpenStatic,adUseCilentBatch,adCmdText为adovbs.inc定义的常量,要使用的话要把adovbs.inc拷到当前目录中并包含于在程序中

<!--#Include File=”adovbs.inc”-->

2. PrintFielName,PrintFieldValue函数的代码如下:

 

<%

Function PrintFieldName(objMyRst)

'参数objMyRst是Recordset对象

'定义娈数

Dim objFld

Response.Write "<tr bgcolor='#CCCCCC'>"

For Each objFld In objMyRst.Fields

Response.Write "<td>" & objFld.Name & "</td>"

Next

Response.Write("</tr>")

End Function

Function PrintFieldValue(objMyRst)

'参数objMyRst是Recordset对象

'定义娈数

Dim objFld

Response.Write("<tr >")

For Each objFld In objMyRst.Fields

'Response.Write "<td>" & objMyRst.Fields(intLoop).value & "</td>"

Response.Write "<td>" & objFld.value & "</td>"

Next

Response.Write("<tr>")

End Function
