SUMMARY
This article describes how to use the PageSize, PageCount, and AbsolutePage properties of an ADO recordset and what cursor types must be used to get Recordset Paging to work.



MORE INFORMATION
This sample code demonstrates using Recordset Paging against the Adventure Works Access database.

The code Assumes the system DSN named AdvWorks is pointing to the Adventure Works Access 97 database. <%@ EnableSessionState=False Language=VBScript %> <% set conn = Server.CreateObject("ADODB.Connection") conn.Open "DSN=AdvWorks"

set rs = Server.CreateObject("ADODB.Recordset") rs.CursorLocation = 3 ' adUseClient rs.Open "Select * from Employees", conn rs.PageSize = 2 intPageCount = rs.PageCount

Select Case Request("Action") case "<<" intpage = 1 case "<" intpage = Request("intpage")-1 if intpage < 1 then intpage = 1 case ">" intpage = Request("intpage")+1 if intpage > intPageCount then intpage = IntPageCount Case ">>" intpage = intPageCount case else intpage = 1 end select %>    ASP & ADO Paging  

<% rs.AbsolutePage = intPage For intRecord = 1 To rs.PageSize Response.Write "Record number: " & intRecord & " " Response.Write rs.Fields("FirstName") & " " Response.Write rs.Fields("LastName") & " " rs.MoveNext If rs.EOF Then Exit For

Next

rs.Close set rs = Nothing conn.Close set conn = nothing %>  ">   "> >"> Page: <%=Intpage & " of " & intpagecount%> </BODY> </HTML>

When using Recordset Paging against SQL Server, you can use a server side cursor. However, you must use either a Static or a Keyset cursor type. Otherwise, no data will be returned. If you use a client side cursor, all cursor types will work, but only a static cursor is returned.

When using Recordset Paging against Microsoft Access, you must use a client side cursor. Any cursor type will work, but again only a static cursor is returned. A server side cursor will not return any data.

When using Recordset Paging against Oracle, you can use a server side cursor, but if you do, you must use a Static or Keyset cursor type. Otherwise, no data will be returned. If you use a client side cursor, all cursor types will work, but only a keyset cursor is returned.
