Weather Observation Station 5

  • marinskiy + 0 comments

    Here is Oracle solution from my HackerrankPractice repository:

    SELECT *
FROM
    (SELECT CITY, LENGTH(CITY)
    FROM STATION
    ORDER BY LENGTH(CITY), CITY)
WHERE ROWNUM = 1
UNION
SELECT *
FROM
    (SELECT CITY, LENGTH(CITY)
    FROM STATION
    ORDER BY LENGTH(CITY) DESC, CITY)
WHERE ROWNUM = 1;

    Feel free to ask if you have any questions :)
