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

I prefer:

select right(email_address, length(email_address)-INSTR(email_address, '@')) ...

so you don't have to guess how many sub-domains your user's email domain has.
