Speedkini Brand Rankings

In my leisure time, I continue to develop new features for speed-kini.de. The latest addition is a brand ranking which should advise the user on which brand is the fastest. There are three different categories: for board, sail and fin companies. The brands of the first-placed get 30 points, the brands of the second-placed rider get 29 and so on…

The results are computed LIVE using simple SQL and a helper. The helper view produces data like this:

SELECT     
      `b`.`name`                                    AS `Name`,     
      sum((31 - `h`.`Rang`))                        AS `Punkte` FROM 
     (`speedkini_ranking_helper` `h`      
JOIN 
    `speedkini_equipment_brand` `b`) WHERE 
     ((`h`.`Boardbrand` = `b`.`ID`) AND (`h`.`Rang` <= 30)) GROUP BY 
     `h`.`Boardbrand` ORDER BY 
     sum((31 - `h`.`Rang`)) DESC;
