I want to query the list of CITY names from the table STATION(id, city, longitude, latitude) which have vowels as both their first and last charact
CITY
STATION(id, city, longitude, latitude)
You may try this
select city from station where SUBSTRING(city,1,1) in ('A','E','I','O','U') and SUBSTRING(city,-1,1) in ('A','E','I','O','U');
