MYSQL与多个外键创建表错误

Question

我想创建一个具有多个外键的表，并且出现错误。我不确定我做错了什么，我一直在修补它。我敢肯定，它的东西小而笨，但帮助表示赞赏。

Create table Order(
order_number INT AUTO_INCREMENT, 
product_id INT(11) NOT NULL, 
address_id INT(11) NOT NULL, 
user_id INT(11) NOT NULL, 
quantity INT(3) NOT NULL, 
size VARCHAR(20) NOT NULL, 
status VARCHAR(20) NOT NULL, 
order_date DATE NOT NULL, 
PRIMARY KEY (order_number), 
FOREIGN KEY (user_id) 
REFERENCES User (user_id), 
FOREIGN KEY (product_id) 
REFERENCES Product (product_id), 
FOREIGN KEY (address_id) 
REFERENCES Address (address_id) 
)ENGINE = INNODB 

特定的错误我得到的是：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Order(

ORDER_NUMBER INT AUTO_INCREMENT， 的product_id INT（11）NOT NULL， 地址_”在行1

Answer 1

你不能只用order，因为它也是一个关键字;放在引号：

Create table `Order`(
order_number INT AUTO_INCREMENT, 
product_id INT(11) NOT NULL, 
address_id INT(11) NOT NULL, 
user_id INT(11) NOT NULL, 
quantity INT(3) NOT NULL, 
size VARCHAR(20) NOT NULL, 
status VARCHAR(20) NOT NULL, 
order_date DATE NOT NULL, 
PRIMARY KEY (order_number), 
FOREIGN KEY (user_id) 
REFERENCES User (user_id), 
FOREIGN KEY (product_id) 
REFERENCES Product (product_id), 
FOREIGN KEY (address_id) 
REFERENCES Address (address_id) 
)ENGINE = INNODB
