mysql Opposite of SUBSTRING_INDEX

Question

I can select the text string before the @ character:

sample entry in DB: email@domain.com , sample output: email

with:

SELECT SUBSTRING_INDEX(email,'@',1)

but what is the command for selecting text string after the @ character ?

Thank you

Answer 1

Use a negative value for count like this:

SELECT SUBSTRING_INDEX(email,'@',-1)

See the documentation here:
