MYSQL與多個外鍵創建表錯誤

Question

我想創建一個具有多個外鍵的表，並且出現錯誤。我不確定我做錯了什麼，我一直在修補它。我敢肯定，它的東西小而笨，但幫助表示讚賞。

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 

特定的錯誤我得到的是：

#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，因爲它也是一個關鍵字;放在引號：

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
