Weather Observation Station 5

  • lvrosa + 2 comments

    Without use of variables (MySQL):

    SELECT CITY,LENGTH(CITY) FROM STATION WHERE LENGTH(CITY) = (
    SELECT MIN(LENGTH(CITY)) FROM STATION
) ORDER BY CITY LIMIT 1;

SELECT CITY,LENGTH(CITY) FROM STATION WHERE LENGTH(CITY) = (
    SELECT MAX(LENGTH(CITY)) FROM STATION
) ORDER BY CITY LIMIT 1;

      Hi, I'm wondering - why does WHERE LENGTH(CITY) = MAX(LENGTH(CITY)) not work? I get a "Invalid use of group function" error.

        Double check that you're not using Oracle, but that you're using MySQL

        That's because you need to use 'having' when you use a group function like max or length
