mysql – 创建表时出错:你的SQL语法中有一个错误’order(order_id INT UNSIGNED NOT NULL AUTO_INCREMENT,user_id’在第1行

参见英文答案 > Syntax error due to using a reserved word as a table or column name in MySQL 1个
我试图用PHP脚本在同一MySQL数据库中创建2个表:
具有主键’user_id’的表’user’和具有主键’order_id’的表’order’和来自’user’表的外键’user_id'(1到多个关系).
表用户成功创建没有问题:
$sql="CREATE TABLE user(
user_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
type ENUM('member','admin') NOT NULL,
username VARCHAR(30) NOT NULL,
email VARCHAR(80) NOT NULL,
pass VARBINARY(32) NOT NULL,
first_name VARCHAR(40) NOT NULL,
last_name VARCHAR(40) NOT NULL,
date_expires DATE NOT NULL,
date_created TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
date_modified TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',
PRIMARY KEY (user_id),
UNIQUE (username),
UNIQUE (email)
)ENGINE=InnoDB DEFAULT CHARSET=utf8";
但是,我无法创建表顺序:
$sql="CREATE TABLE order(
order_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
user_id INT UNSIGNED NOT NULL,
transaction_id VARCHAR(19) NOT NULL,
payment_status VARCHAR(15) NOT NULL,
payment_amount DECIMAL(6,2) UNSIGNED NOT NULL,
payment_date_time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (order_id),
FOREIGN KEY (user_id) REFERENCES user (user_id)
)ENGINE=InnoDB DEFAULT CHARSET=utf8";
我收到以下错误:
Error creating table: 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_id INT UNSIGNED NOT NULL AUTO_INCREMENT, user_id ' at line 1
已经检查了语法,找不到错误.你能告诉我出了什么问题吗?非常感谢.
解决方法:
你需要使用反引号来逃避reserved words
CREATE TABLE `order` ( ...
或者更好地使用其他名称.
