GuestInfoとReservationの2つのテーブルでINNER JOINを使用します
select RoomNo, DateStart, DateEnd, GuestFName, GuestMName, GuestLName
from GuestInfo inner join Reservation
on GuestInfo.GuestID = Reservation.GuestID
今、そのINNER JOINED TABLEを更新したい
update (select RoomNo, DateStart, DateEnd, GuestFName, GuestMName, GuestLName
from GuestInfo inner join Reservation
on GuestInfo.GuestID = Reservation.GuestID) set EndDate = '1/20/2014'
where GuestFName = 'JAKE'
しかし、このクエリはエラーです。これは可能ですか?
