Answer 1

尝试此查询

select User_id,auction_id,price from tablename where price in(select price from tablename where id in(select max(id) from tablename group by user_id)) 

Answer 2

如果已经更新输出错误，然后尝试按你提供的条件 -

select user_id,auction_id,price 
from mytable 
where user_id=41 
order by auction_id; 

但如果按你的输出你想要的user_id 1个最新行= 41，然后最高价的所有行，那么你可以尝试一下它 -

SELECT user_id,auction_id,price 
FROM mytable 
WHERE user_id=41 
ORDER BY id DESC LIMIT 1 
UNION 
SELECT b.user_id,b.auction_id,price 
FROM mytable b 
JOIN (
SELECT MAX(price) AS price 
FROM mytable 
) a ON a.price=b.price; 

Answer 3

根据你的输出，你想试试这个：

select user_id,auction_id,price 
from table_name 
where user_id=41 
order by id desc;
