舞哈哈哈：使用MySQL做的，个人理解 select t1.order_add_user, t1.num, count(distinct t2.num)+1 as rank, (case when count(distinct t2.num)+1<=3 then t1.num*50+1000 else t1.num*50 end) as bonus from (select order_add_user, sum(quantity) as num, date_format(order_add_time,"%Y-%m") as month from order where order_add_time<=date_format(now(),"%YYYY-%mm-%dd") and order_add_time>date_format(now(),"%Y-%m-01") group by order_add_user order by num desc limit 10 ) t1 left join (select order_add_user, sum(quantity) as num, date_format(order_add_time,"%Y-%m") as month from order where order_add_time<=date_format(now(),"%YYYY-%mm-%dd") and order_add_time>date_format(now(),"%Y-%m-01") group by order_add_user order by num desc limit 10 ) t2 on t1.num<t2.num group by t1.order_add_user order by t1.num desc;
