How to do this with one query?

Question

here is the basic query
<cfquery name="getCenturies"
datasource="#application.dsn#">
SELECT riderId, rideDistance, rideDate
FROM mileageLog
WHERE rideDistance > 99
</cfquery>
and my results would be something like
Kevin 114
Chris 103
Kevin 100
Don 102
Kevin 106
Now how can I get the count for each person
Kevin 3
Chris 1
Don 1

in the SELECT statement change rideDistance to
SUM(rideDistance) - i
think that is what you want to get anyway, isn't it? - and
you won't get
that error. it's not the SELECT statement you have to have
the vars
listed in; it's either in the GROUP BY or use an aggregate
function on it..
