CREATE TABLE example_items (
    id INT AUTO_INCREMENT PRIMARY KEY,
    example_id INT,
    value VARCHAR(255),
    FOREIGN KEY (example_id) REFERENCES example(id)
);

INSERT INTO example () VALUES ();
SET @example_id = LAST_INSERT_ID();
INSERT INTO example_items (example_id, value) VALUES (@example_id, 'value1'), (@example_id, 'value2'), (@example_id, 'value3');

SELECT * FROM example_items WHERE example_id = 1;
