构建SQL查询的表结构

Question

对于下面的表结构 预订 领域 - BookingID（主键），客户ID，SeatPref

我想这是大多数CustIDs首选SeatPref。

请帮忙。

Answer 1

select 
    seatpref, 
    count(seatpref) as PrefCount 
from 
    Bookings b 
group by 
    seatpref 
order by 
    count(seatpref) desc 

Answer 2

我觉得

SELECT SeatPref, count(SeatPref) AS NumCusts 
FROM your_table 
GROUP_BY SeatPref 
ORDER_BY NumCusts 

应该这样做。
