find new record on click

[samoht]

Hello again,

 

I want to make a next and a previous link with my data.

 

here is my query:

<?php $sql = "SELECT DISTINCT pdp.PackageId, p.PackageType 
                            FROM productpackaging pdp, packaging p 
                            WHERE pdp.ProductId =2 
                            AND pdp.PackageId = p.PackageId";
				$result = mysql_query($sql);

 

How do I write the code to get next or get previous??
