<?php
include("db/connect.php");
    $pagesize = 20;
	$sql="select * from job_code ";
	$teblejobcode =mysql_query($sql) or die("Error : $sql".mysql_error());
	$count = mysql_num_rows($teblejobcode);
	$totalpage  =ceil ($count/$pagesize);
	if(empty($_REQUEST['pageno']))
			$pageno =0;
	else
			$pageno =$_REQUEST['pageno'];
	$pointer =$pageno *$pagesize;
	$sql.="Limit $pointer,$pagesize" ;
	$teblejobcode =mysql_query($sql) or die("Error : $sql".mysql_error());
