Question

我试图在phpMyAdmin中执行一个查询，但它给了我一个错误说：

1064 - 您的SQL语法出错;检查手册对应于您的MySQL服务器版本，以便使用正确的语法靠近＆＃39;）参考Online Shopping。Customer（）无法删除操作＆＃39;在第11行

查询是：

CREATE  TABLE IF NOT EXISTS `Online Shopping`.`Order_Details` (
  `Order_Id` INT NOT NULL ,
  `Product_Name` VARCHAR(45) NULL ,
  `Price_For_Each_Product` VARCHAR(45) NULL ,
  `No_of_Product_ordered` VARCHAR(45) NULL ,
  `Ordered_Date` DATE NULL ,
  `Total_Price` VARCHAR(45) NULL ,
  `Generated_Key` VARCHAR(45) NULL ,
  PRIMARY KEY (`Order_Id`) ,
  CONSTRAINT `Customer_Id`
    FOREIGN KEY ()
    REFERENCES `Online Shopping`.`Customer` ()
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `Order_LineId`
    FOREIGN KEY ()
    REFERENCES `Online Shopping`.`Order_Line` ()
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

CREATE  TABLE IF NOT EXISTS `Online Shopping`.`Order_Details` (
  `Order_Id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT ,
  `Product_Name` VARCHAR(45) NULL ,
  `Price_For_Each_Product` VARCHAR(45) NULL ,
  `No_of_Product_ordered` VARCHAR(45) NULL ,
  `Ordered_Date` DATE NULL ,
  `Total_Price` VARCHAR(45) NULL ,
  `Generated_Key` VARCHAR(45) NULL,
  CONSTRAINT `Customer_Id`
    FOREIGN KEY (Customer_ID)
    REFERENCES `Online Shopping`(Customer)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `Order_LineId`
    FOREIGN KEY (Customer_ID)
    REFERENCES `Online Shopping`(Order_Line)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;
