Lets say my database has some useful widget information in different tables as follows...

~ Widget title
~ Widget brand
~ Widget distributor

There are many brands which are in turn available from many distributors.

How would I print a list of brands that are available by at least TWO or more distributors?

$sql = "SELECT DISTINCT(distributor) FROM `".$config_databaseTablePrefix."widgets` ORDER BY distributor";

 if (database_querySelect($sql,$rows))
 {
  foreach($rows as $product)
  {
   $item = array();

   $item["name"] = $product["distributor"];

From there... how would I implement a check to see if a brand has at least 2 distributors?
