php - Display only the last 300 MYSQL Results with a PHP pagination system

Question

Hi I have a system where I only want to display the last 300 records from MYSQL, normally i would just write the query like this LIMIT 300

the problem i have is i am using a pagination system which writes the query like this.

    $tableName="masterip_details";      
$targetpage ="raw_data.php";    
$limit = 30; 

$query = "SELECT COUNT(*) as num FROM $tableName where type='6' AND country_code='GB'";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];

$stages = 3;
$page = mysql_escape_string($_GET['page']);
if($page){
    $start = ($page - 1) * $limit; 
}else{
    $start = 0; 
    }   

// Get page data
$query1 = "SELECT * FROM $tableName where type='6' AND country_code='GB' LIMIT $start, $limit";
$result = mysql_query($query1);

The problem is because it uses the limit to calculate the start and finish page numbers i am not sure if i can limit the number of rows to return whilst using the pagination.

Answer 1

select * from (SELECT * FROM $tableName where type='6' AND country_code='GB' order by AUTO_INCERMENT_ID DESC LIMIT 300) as a order by AUTO_INCERMENT_ID ASC LIMIT $start, $limit
