Solution
To create a view 'ShortestCity' to find the shortest CITY names and their respective lengths, you can use the SQL language. Here is a step-by-step guide on how to do it:
Step 1: Start by selecting the CITY and the length of the CITY from the STATION table. You can use the LENGTH function to get the length of the CITY.
SELECT CITY, LENGTH(CITY) as length
FROM STATION
Step 2: Order the result by the length of the CITY in ascending order and then by the CITY in ascending order. This will ensure that the city with the shortest name comes first and if there are cities with the same shortest length, the one that comes first alphabetically will be displayed first.
SELECT CITY, LENGTH(CITY) as length
FROM STATION
ORDER BY length ASC, CITY ASC
Step 3: As you only want the city with the shortest name, you can limit the result to the first row.
SELECT CITY, LENGTH(CITY) as length
FROM STATION
ORDER BY length ASC, CITY ASC
LIMIT 1
Step 4: Finally, create a view 'ShortestCity' with the above query.
CREATE VIEW ShortestCity AS
SELECT CITY, LENGTH(CITY) as length
FROM STATION
ORDER BY length ASC, CITY ASC
LIMIT 1
Now, you can use the 'ShortestCity' view to easily find the city with the shortest name and its length.
