Query the two cities in STATION with the shortest and longest CITY names, as well as their respective lengths (i.e.: number of characters in the name). If there is more than one smallest or largest city, choose the one that comes first when ordered alphabetically.
Input Format
The STATION table is described as follows:
Filed | Type |
---|---|
ID | NUMBER |
NAME | VARCHAR2(17) |
COUNTRYCODE | VARCHAR2(3) |
DISTRICT | VARCHAR2(20) |
POPULATION | NUMBER |
where LAT_N is the northern latitude and LONG_W is the western longitude.
Sample Input
Let’s say that CITY only has four entries: DEF, ABC, PQRS and WXY
Sample Output
ABC 3
PQRS 4
Explanation
When ordered alphabetically, the CITY names are listed as ABC, DEF, PQRS, and WXY, with the respective lengths and . The longest-named city is obviously PQRS, but there are options for shortest-named city; we choose ABC, because it comes first alphabetically.
Note
You can write two separate queries to get the desired output. It need not be a single query.
ANS
SELECT CITY,LENGTH(CITY)
FROM STATION
WHERE LENGTH(CITY)=(SELECT MAX(LENGTH(CITY)) FROM STATION)
LIMIT 1;
SELECT CITY,LENGTH(CITY)
FROM STATION
WHERE LENGTH(CITY)=(SELECT MIN(LENGTH(CITY)) FROM STATION)
LIMIT 1
ORDER BY CITY;
Expected Output
Amo 3
