     user1, 10, 1; 
     user2, 15, 1; 
     user3, 20, 1; 
     user4, 10, 2;

from       (SELECT user.points 
            FROM user
            ORDER BY user.points DESC
            LIMIT 2
            ) user

Answer 1

According to my understanding the below query will give you the desire result

Select user.id_user,SUM(subligue.points) AS TOTAL from user inner join subligue on user.id_subligue=subligue.id_subligue
order by subligue.points DESC

//New Solution

select   SUM(user.points) AS TOTAL
from     (Select top 2  user.points from user inner join subligue on user.id_subligue=subligue.id_subligue
order by  user.points DESC ) user

//We can use where clause for getting specific result for id_subligue

select   SUM(user.points) AS TOTAL
from     (Select top 2  user.points from user inner join subligue on user.id_subligue=subligue.id_subligue where user.id_subligue=1 
order by  user.points DESC ) user

As Question is not very clear to me and if this above solution do not working then let me know the final output you want.
