regexp_like similar function in MySQL?

Question

I was trying to solve a problem in SQL and I came across the problem:

Query the list of CITY names from STATION table that do not start with vowels. Your result cannot contain duplicates.

I used regexp_like() function using Oracle but how I can query the results using MySQL?

In Oracle I did regexp_like(city, '^[^aeiou]', 'i')

Answer 1

MySQL has a REGEXP keyword for just such an occasion.

SELECT ...
FROM ...
WHERE field REGEXP 'expression';

See: http://dev.mysql.com/doc/refman/5.7/en/regexp.html (first Google result for MySQL REGEXP)

Answer 2

Select distinct City 
from Station 
where Left(Upper(city),1)) 
not like '%[AEIOU]%'
