我在 SQL Server 中有一个表，用户需要在其中的两列中输入数据。也就是说，两者之一必须输入数据，但同时我不想让用户在两列中输入。它要么是要么，但一个是必须的。

我在我的数据库上运行这个选择查询：

Select Item.ItemId, Item.ItemDescription, Bid.BidPrice, bid.BidDate,
Sum(bid.bidPrice) over () as TotalBids
from Bid
inner join Item on bid.ItemId=Item.ItemId
where BidDate between '2016-08-24' and '2017-11-15'

我得到以下结果：

ItemId  ItemDescription BidPrice    BidDate     TotalBids
1       Frame           35         2016-08-24   3624
4       Wooden chair    40         2016-10-25   3624
2       Car             3000       2017-10-26   3624
3       Stand Fan       29         2017-10-30   3624
5       Black Sofa      400        2017-11-11   3624
6       Cabinet         120        2017-11-15   3624

我的问题是：是否有可能Total Bids在每行的列中得到一个总数，而不是在列的底部得到一个总数BidPrice？

我在我的 sql server 2012 数据库上运行以下查询。

select Appointment.AppointmentDate, Appointment.AppointmentTime,   Auctioneer.AuctioneerName, Auctioneer.AuctioneerSurname, Buyer.BuyerName,   Buyer.BuyerSurname  
from Appointment  
inner join Auctioneer on Appointment.AuctioneerId=Auctioneer.AuctioneerId  
inner join Buyer on Appointment.BuyerId=Buyer.BuyerId  
where AppointmentDate between '2017-01-01' and '2017-12-31' 

结果如下：

+-----------------+-----------------+----------------+-------------------+-----------+----------------+
| AppointmentDate | AppointmentTime | AuctioneerName | AuctioneerSurname | BuyerName | BuyerSurname   |
+-----------------+-----------------+----------------+-------------------+-----------+----------------+
