ASP实现以分页的形式显示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
%>
