Weather Observation Station 5

  • VJ5189 + 5 comments

    Here is the answer in oracle without union and in single sql statement.

    select MIN(city) , length(city) from station group by length(city) having length(city) =(select MIN(length(city)) from station ) or length(city) =(select MAX(length(city)) from station ) order by length(city) ASC;

        is there a way to do in mysql?

          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
)

                ( 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 )

            select LENGTH(city) as `length` from table station order by length asc, city asc limit 1) union (select length(city) as `length` from table station order by length desc, city asc limit 1);

          Select top 1 city, len(city) from Station where Len(City) =(SELECT Min(Len(City))FROM station)order by city ASC

          Select top 1 city, len(city) from Station where Len(City) =(SELECT Max(Len(City))FROM station)order by city ASC

      IT'S INCORRECT if there were more rows with max length = 21 this is not generic it will fail.

      If we remove order by also it will work
