Specific character in sql

Question

I have a table with all employee details including email addresses

Is there any specific query via which I can find the length of the email addresses till the letter '@' is encountered?

if the email address is azxcde@asas.com, then I want to extract the azxcde part of the email.

I am working on sq server management studio, does that answer your question? — Naga, Jul 30 '13 at 06:07

Here is an alternative version using SUBSTRING:

SELECT SUBSTRING(EmailColumnName,0,CHARINDEX(' ',EmailColumnName)) as UserName
FROM tablName
