按过程将外键插入表中不受影响

Question

下面是我用来向表中插入数据的过程，但是当我试图向表中插入数据时，tdd_tv_ZvrstOddaje始终为0。这是因为约束吗？我该如何处理？

创建语句：

CREATE TABLE IF NOT EXISTS `pb2_pb`.`Zvrst_oddaje` (
  `ID_Zvrst` INT NOT NULL,
  `vrstaOddaje` VARCHAR(45) NOT NULL
)
ENGINE = InnoDB;

ALTER TABLE Zvrst_oddaje
ADD CONSTRAINT PK_zvrst_oddaje PRIMARY KEY (ID_Zvrst);

ALTER TABLE Zvrst_oddaje MODIFY COLUMN ID_Zvrst INT AUTO_INCREMENT;

-- -----------------------------------------------------
-- Table `pb2_pb`.`Spored`
-- -----------------------------------------------------
CREATE TABLE IF NOT EXISTS `pb2_pb`.`Spored` (
  `ID_Spored` INT NOT NULL,
  `datumPredvajanja` DATE NOT NULL,
  `casPredvajanja` TIME NOT NULL,
  `aktualno` VARCHAR(45) NOT NULL
)
ENGINE = InnoDB;

ALTER TABLE Spored
ADD CONSTRAINT PK_Spored PRIMARY KEY (ID_Spored);

ALTER TABLE Spored MODIFY COLUMN ID_Spored INT AUTO_INCREMENT;

-- -----------------------------------------------------
-- Table `pb2_pb`.`Oddaja`
-- -----------------------------------------------------
CREATE TABLE IF NOT EXISTS `pb2_pb`.`Oddaja` (
  `ID_Oddaja` INT NOT NULL,
  `imeOddaje` VARCHAR(45) NOT NULL,
  `dolzinaTrajanja` DATETIME NOT NULL,
  `frekvencaOddaje` VARCHAR(45) NOT NULL,
  `TK_ZvrstOddaje` INT NOT NULL,
  `TK_Spored` INT NOT NULL
  )
ENGINE = InnoDB;

ALTER TABLE Oddaja
ADD CONSTRAINT PK_Oddaja PRIMARY KEY (ID_Oddaja);

ALTER TABLE Oddaja
ADD CONSTRAINT FK_Zvrst_oddaje FOREIGN KEY (TK_ZvrstOddaje) REFERENCES Zvrst_oddaje(ID_Zvrst);

ALTER TABLE Oddaja
ADD CONSTRAINT FK_Spored FOREIGN KEY (TK_Spored) REFERENCES Spored(ID_Spored);

ALTER TABLE Oddaja MODIFY COLUMN ID_Oddaja INT AUTO_INCREMENT;

我正在尝试致电polni_zvrst_oddaje（3），polni_spored（10），polni_oddaja（10）
