Answer 1

This is an aggregation query:

select userid, factorid, sum(economy), sum(vip), sum(count)
from tb_orders
group by userid, factorid;

Aggregation is a very basic part of SQL functionality. If you don't recognize it, I would suggest that you brush up on your SQL skills with a tutorial, book, or something like that.
