Query the two cities in STATION with the shortest and longest CITY names, [closed]

Answer 1

Try this one using UNION:

SELECT MIN(city), LENGTH(city)
FROM Station
WHERE LENGTH(city) =
(SELECT MIN(LENGTH(city))
FROM Station)
UNION
SELECT MIN(city), LENGTH(city)
FROM Station
WHERE LENGTH(city) =
(SELECT MAX(LENGTH(city))
FROM Station)

Of course, my assumption is that your table name is Station and column name is City. See the related post below about only choosing the first record alphabetically:
