SELECT DISTINCT
Name,
Username,
Password,
Address,
Email,
CCNumber,
CCExpiration,
ItemsSold
FROM auctionsite.dbo.Seller
JOIN (SELECT MAX(ItemsSold) AS id FROM auctionsite.dbo.Seller GROUP BY
ItemsSold) max ON id = max.id
您可以使用order by和逻辑获取一行:
select s.*
from auctionsite.dbo.Seller s
order by s.itemSold desc
fetch first 1 row only;
注意:如果存在绑定,则只获取一个绑定行
如果需要所有关系,有一种方法使用子查询:
select s.*
from auctionsite.dbo.Seller s
where s.itemSold = (select max(s2.itemSold) from auctionsite.dbo.Seller s2);
