Buat Kesalahan Tabel - Oracle SQL

Anda tampaknya mencoba mendeklarasikan kunci asing sebaris dan sintaksnya salah, Anda ingin:

CREATE TABLE B_BOOKING (
    booking_number int PRIMARY KEY,
    date_booked date,
    performance_order int,
    base_pay int,
    band_number int,
    concert_number int REFERENCES B_CONCERT(concert_number)
)

Juga, Anda tidak memerlukan NOT NULL batasan pada PRIMARY KEY kolom.

Atau Anda dapat mendeklarasikan batasan sebagai:

CREATE TABLE B_BOOKING (
    booking_number int PRIMARY KEY,
    date_booked date,
    performance_order int,
    base_pay int,
    band_number int,
    concert_number int,
    CONSTRAINT constraint_name FOREIGN KEY ( concert_number )
                               REFERENCES B_CONCERT(concert_number)
)
