无法绑定多部分标识符“Reservation.ReservationID”

Question

我正在尝试这样的内部连接。

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

我收到的错误为：

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

别名 “R” 和 “P” 掩盖了实际的表名。

尽管这里不适用，但它通常是有意义的。例如，当你有一个自联接

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

尝试，而不是

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

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