Here is my two tables, I want to pass my guest_id as a foreign key inside reservation table. but it's given error..
$sql = "CREATE TABLE MyGuests (
guest_id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)";
// // sql to create table
$sql = "CREATE TABLE reservation (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
FOREIGN KEY(guest_id) REFERENCES MyGuests(guest_id),
room INT(11) NOT NULL,
price FLOAT(11) NOT NULL,
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)";
where is the problem?
You need also add the column guest_id to your table reservation
Like:
$sql = "CREATE TABLE MyGuests (
guest_id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)";
// // sql to create table
$sql = "CREATE TABLE reservation (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
guest_id INT(6) UNSIGNED,
room INT(11) NOT NULL,
price FLOAT(11) NOT NULL,
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
FOREIGN KEY(guest_id) REFERENCES MyGuests(guest_id)
)";
