how do I trim an email input address so only the data before the @ is inputted into the database?

问题

I am using coldfusion 9 to add data into a MySQL database from a form.

I would like to create a username from the email address inputed into the form.

for example,

<cfset store_user_email = EMAILADDRESS>
<cfset store_username = trim EMAILADDRESS before the @>

I'm not sure how to trim down the email address?

Any help would be much appreciated.

<cfset store_username = trim(listFirst(EMAILADDRESS,"@"))>
