構建SQL查詢的表結構

Question

對於下面的表結構 預訂 領域 - BookingID（主鍵），客戶ID，SeatPref

我想這是大多數CustIDs首選SeatPref。

請幫忙。

Answer 1

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

Answer 2

我覺得

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

應該這樣做。
