необходимо создать две таблицы:

CREATE table users ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, email VARCHAR(50) NOT NULL, password VARCHAR(255) NOT NULL, verified BOOLEAN DEFAULT FALSE );

CREATE TABLE items ( id INT AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255) NOT NULL, description TEXT NOT NULL, photo VARCHAR(255) NOT NULL, price DECIMAL(10, 2) NOT NULL, email VARCHAR(255) NOT NULL );
