I have a query that looks like:

  SELECT SUM(bytes) AS traffic
    FROM traffic_table
GROUP BY ip;

I want to narrow that SELECT down to a subset, like:

   SELECT SUM(bytes) AS traffic
     FROM traffic_table
    WHERE traffic < ( 100 * 1024 * 1024 )
 GROUP BY ip;

which, of course, won't work, cause I need to do the GROUP BY before I do
the WHERE ... but there has to be a way of coding that so that it does
work :(

I'm overlooking something obvious here ... I think?

Thanks ...
