Estoy tratando de crear una base de datos con varias claves externas con restricciones de eliminación / actualización, pero obtuve un código de error 1005 con los siguientes scripts de SQL:

CREATE TABLE Worker (
 WorkerID smallint auto_increment,
 WorkerType  varchar(45) NOT NULL,
 WorkerName  varchar(45) NOT NULL,
 Position    varchar(45) NOT NULL,
 TaxFileNumber int NOT NULL,
 Address    varchar(100) ,
 Phone      varchar(20) ,
 SupervisorID  smallint ,
 PRIMARY KEY (WorkerID),
 FOREIGN KEY (SupervisorID) REFERENCES Worker(WorkerID)
    ON DELETE SET NULL
    ON UPDATE CASCADE
)Engine=InnoDB;

CREATE TABLE Grape (
    GrapeID smallint NOT NULL,
    GrapeType varchar(45) NOT NULL,
    JuiceConversionRatio int,
    StorageContainer ENUM('Stainless Steel Tank','Oak Barrel'),
    AgingRequirement int,
    PRIMARY KEY (GrapeID)
)Engine=InnoDB;

CREATE TABLE Vineyard (
    VineyardID smallint auto_increment,
    VineyardName VARCHAR(45) NOT NULL,
    FarmerID    smallint NOT NULL,
    GrapeID smallint NOT NULL,
    ComeFrom    varchar(45) NOT NULL,
    HarvestedAmount int,
    RipenessPercent int,
    PRIMARY KEY (VineyardID),
    FOREIGN KEY (FarmerID) REFERENCES Worker(WorkerID)
        ON DELETE SET NULL
        ON UPDATE CASCADE,
    FOREIGN KEY (GrapeID) REFERENCES Grape(GrapeID)
        ON DELETE SET NULL
        ON UPDATE CASCADE
)Engine=InnoDB;

El código de error dice que al no crear la tabla Vineyard, solo quiero saber el formato adecuado para crear varias claves externas con el control de eliminar / actualizar.
