CSV update Mysql feature

hi all, What I am trying to achieve to no avail is the following I export values from a Mysql db into CSV format for quick updates and that works fine.. <http://www.xarex.com/jantar/admin/pick_csv.php> www.xarex.com/jantar/admin/pick_csv.php But as you can see from the page you can select the options that you want to d/l I am going to make ID compulsory but its not necessary for the time being, The problem that I am having is with the update Mysql feature What I need to happen is the first line of the CSV is the headings (db field names) So that when I do the update it only updates the fields that were chosen on the pick_csv page. Now I will have no way of knowing before hand what fields will be chosen so I will have to create the update Mysql query on the fly, I hope this is clear enough any help will be great K-
