Answer 1

This Query will work well in your condition these 2 query are exactly same. In the first query we just ordering the recording in descending order to take the city name with the highest length and in the second part we are just taking records in the ascesding order to take city with the minimum lenght all the rest query is same. Kidnly have a look.

Detail:

1. Select statement to take out records
2. Use group by clause because I am using Len() aggregating function.

3. Ordering all the retrieved records in the descending and ascending order to get the top 1 and take max and min length city.

   select  Top 1  City,max(len(City)) as Length  
   from STATION 
   group by City 
   ORDER BY Length desc 
   
   select  Top 1  City,max(len(City)) as Length  
   from STATION 
   group by City 
   ORDER BY Length ASC
