构建表结构的SQL查询

Question

对于下表结构 预订 字段 - BookingID（主键），CustID，SeatPref

我想获得大多数CustID首选的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

我认为

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

应该这样做。
