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

select (SUBSTRING_INDEX(SUBSTR(email, INSTR(email, '@') + 1),'.',1) from tableName)

Some sql statements require the table name specified where the email column belongs to.
