Problem
Query the list of CITY names from STATION that either do not start with vowels or do not end with vowels. Your result cannot contain duplicates.
The STATION table is described as follows:
→ 모음으로 시작하지 않거나 모음으로 끝나지 않는 CITY names, 중복X
My Answer
SELECT DISTINCT CITY
FROM STATION
WHERE CITY REGEXP '^[^aeiou]' OR CITY REGEXP '[^aeiou]$'
* REGEXP에 대한 내용은 Weather Observation Station 6 포스팅 참고
