Question

我正在尝试将表连接到数据库中的两个不同的表。我收到了下一个错误：

错误代码：1005。无法创建表project。orders（错误号：150 “外键约束不正确”）0.625秒

连接的表是：

CREATE TABLE IF NOT EXISTS  ORDERS
(
ORDER_ID INT NOT NULL UNIQUE auto_increment,
PRICE INT NOT NULL,
ORDERED_DATA timestamp default now(),
clients_ID INT,
product_second_ID int,
PRIMARY KEY(ORDER_ID),
 INDEX `fk_orders_clients1_idx` (`clients_ID` ASC),
  INDEX `fk_orders_product_second1_idx` (`product_second_ID` ASC),
  CONSTRAINT `fk_orders_clients1`
    FOREIGN KEY (`clients_ID`)
    REFERENCES `schooldb`.`clients` (`ID`)
    ON DELETE CASCADE
    ON UPDATE CASCADE,
  CONSTRAINT `fk_orders_product_second1`
    FOREIGN KEY (`product_second_ID`)
    REFERENCES `schooldb`.`product_second` (`ID`)
    ON DELETE CASCADE
    ON UPDATE CASCADE
);

将要连接的其他两个表：

CREATE TABLE IF NOT EXISTS  Product_SECOND (
ID INT  NOT NULL unique auto_increment,
NUME CHAR(24) not NULL,
STOCK INT,
RESTOCKED  timestamp default now() on update now(),
ADDED timestamp default now(),
PRIMARY KEY(ID)
);

CREATE TABLE IF NOT EXISTS  CLIENTS
(
ID int NOT NULL unique auto_increment,
NUME CHAR(24) NOT NULL,
PRENUME CHAR(24)  NOT NULL,
EMAIL CHAR(24),
PASSWORD_user CHAR(10) NOT NULL,
PHONE INT,
ADDRESS CHAR(50) NOT NULL,
DATE_CREATE_ACCOUNT  timestamp default now(),
DATE_OF_LAST_ORDER timestamp default now() on update now(),
PRIMARY KEY(ID)
);

外键约束形成错误 - MYSQL
