LIMIT within GROUP BY

[Miroslav Monkevic]

Hello,

MySQL 4.1

I have query:
SELECT SUM(points) as ranking FROM results GROUP BY person_id ORDER BY 
ranking DESC

My goal is to sum 7 greatest results for each person.

In more general, my question is: is there a way to limit number of 
records within  groups in  "group by" query.

Thank you!
