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

Answer 1

Here is another way to do it using the always handy row_number analytic function:

with cte as (
  select city,
         length(city) as len,
         row_number() over (order by length(city), city) as smallest_rn,
         row_number() over (order by length(city) desc, city) as largest_rn
    from station
)
select city, len
  from cte
 where smallest_rn = 1
union all
select city, len
  from cte
 where largest_rn = 1
