分页代码，数据源表没有记录的话就出错，该怎么改啊？
下面的代码，如果数据源表jsb有数据的话可以正常执行，但如果数据表没有记录的话就不能用，请问在数据表没有记录的情况下，怎么修改这段代码啊？
<!--#include file="../conn.asp" -->asp 分页

set rs=server.createobject("adodb.recordset")
rs.open exec,conn,1,1
rs.PageSize=10
pagecount=rs.PageCount
page=int(request.QueryString ("page"))
if page<=0 then page=1
if request.QueryString("page")="" then
page=1
end if
rs.AbsolutePage=page
