無法綁定多部分標識符「Reservation.ReservationID」

Question

我正在嘗試這樣的內部連接。

select R.ReservationID, R.BookingNumber,P.FirstName, P.LastName 
from Reservation R inner join PersonName P 
on Reservation.ReservationID = PersonName.ResrvationID 

我收到的錯誤爲：

Msg 4104, Level 16, State 1, Line 1 
The multi-part identifier "Reservation.ReservationID" could not be bound. 
Msg 4104, Level 16, State 1, Line 1 
The multi-part identifier "PersonName.ResrvationID" could not be bound. 

Answer 1

別名 「R」 和 「P」 掩蓋了實際的表名。

儘管這裏不適用，但它通常是有意義的。例如，當你有一個自聯接

select R.ReservationID, R.BookingNumber,P.FirstName, P.LastName 
from Reservation R inner join PersonName P 
on R.ReservationID = P.ReservationID --use aliasas 

Answer 2

嘗試，而不是

select 
    R.ReservationID 
, R.BookingNumber 
, P.FirstName 
, P.LastName 

from Reservation R 
inner join PersonName P 
on R.ReservationID = P.ResrvationID
