		if intpage < 1 then intpage = 1
	case ">"
		intpage = Request("intpage")+1
		if intpage > intPageCount then intpage = IntPageCount
	Case ">>"

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.
