How to select domain name from email address

Question

I have email addresses like user1@gmail.com, user2@ymail.com user3@hotmail.com ... etc. I want a Mysql SELECT that will trim user name

Answer 1

My suggestion would be (for mysql):

SELECT 
    LOWER(email) AS email,
    SUBSTRING_INDEX(email, '@', + 1) AS account,
 REPLACE(SUBSTRING_INDEX(email, '@', -1), CONCAT('.',SUBSTRING_INDEX(email, '.', -1)),'') -- 2nd part of mail - tld.
  AS domain,
    CONCAT('.',SUBSTRING_INDEX(email, '.', -1)) AS tld
FROM
...
ORDER BY domain, email ASC;
