GROUP BY lname ORDER BY showing wrong results

Question

This query I\'ve written, listing the top 25 in a sales competition, is showing the wrong results.

Users aren\'t showing that should be pretty far up on the list. Any id

Answer 1

Try using a proper, ANSI standard GROUP BY

SELECT
    u.fname, u.lname, SUM(p.point) as points
FROM 
    comp_sale s
    JOIN
    comp_product p ON s.prod_id = p.product_id 
    JOIN
    comp_user u ON s.sale_id = u.wp_id
GROUP BY
    u.fname, u.lname
ORDER BY 
    points DESC 
LIMIT 25

Also, use explicit JOINs for clarity
