    Yes. You also could avoid HAVING keyword and use UNION

    (
    SELECT CITY, LENGTH(CITY) AS `length`
    FROM STATION
    WHERE 1
    ORDER BY `length` ASC, CITY ASC
    LIMIT 1
) UNION (
    SELECT CITY, LENGTH(CITY) AS `length`
    FROM STATION
    WHERE 1
    ORDER BY `length` DESC, CITY ASC
    LIMIT 1
)
