Solution
It seems like you're asking for a SQL query. Here's how you can do it:
SELECT DISTINCT CITY
FROM STATION
WHERE LOWER(SUBSTR(CITY, 1, 1)) IN ('a', 'e', 'i', 'o', 'u');
Here's the step by step explanation:
-
SELECT DISTINCT CITY FROM STATION: This part of the query will select all unique city names from the tableSTATION. -
LOWER(SUBSTR(CITY, 1, 1)): This part of the query will convert the first character of the city name to lowercase. -
IN ('a', 'e', 'i', 'o', 'u'): This part of the query will check if the first character of the city name is a vowel. -
WHERE LOWER(SUBSTR(CITY, 1, 1)) IN ('a', 'e', 'i', 'o', 'u'): This is the condition for the query. It will only select the cities where the first character of the city name is a vowel.
