ASP分页显示Recordset数据

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

%>
