Error creating table: You have an error in your SQL syntax near 'order( order_id INT UNSIGNED NOT NULL AUTO_INCREMENT, user_id ' at line 1

I am trying to create 2 tables in the same MySQL database with a PHP-script:
table ‘user’ with primary key ‘user_id’ and table ‘order’ with primary key ‘order_id’ and foreign key ‘user_id’ from the ‘user’ table (1 to many relationship).

Table user creates successfully without problems:

$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";

However, I am not able to create table order:

$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";

I get the following error:

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

Already checked the syntax and cannot find the mistake. Could you please advise what went wrong? Thanks a lot.

Method 1

You need to escape reserved words like order with backticks

CREATE TABLE `order` ( ...

or better use another name instead.

Method 2

order is keyword used by mysql like (select from tbl_name order by id ASC) so for escaping from using keywords you have to use quotes “ to avoid my sql error

so your query should by

$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";

enjoy 😀
