Question

@NamedQuery(name = "Bookings.findBookedRoomByRoomTypeid", query = "SELECT b.roomno FROM Bookings b, Room r WHERE (b.status = 'checkin') AND (b.roomno = r.oid) AND (r.temproomtypeid = :temproom)" ),

例外是

Answer 1

你可以这样试试

SELECT b.roomno FROM Bookings b, Room r WHERE (b.status = 'checkin') AND (b.roomno =:r.oid) AND (r.temproomtypeid =:temproom)
