How do I pull out a portion of a string?

Question

I have over 2,000 emails in mySQL database with company names as well. Unfortunately, these subscribers do not enter the company name the same. So I came up with the idea to pull the company name from the right side of the @ symbol, ie: [email protected] But try as I may, I have not been able to figure out how to do this. Can anyone help me out here?

If you assume the company name will always exactly match the domain name, you could do this in a WHERE clause of your query.  Assuming you submit a form to start the email process, and the form has a field called "CompanyName":
<CFQUERY Name="Get" datasource="#application.dsn#">
      SELECT email
      FROM users
     WHERE email LIKE <cfqueryparam value="%@#form.CompanyName#.%" cfsqltype="cf_sql_varchar">
</CFQUERY>
NOTE: If you are submitting queries and passing values into the query based on user input (like FORM or URL variables), ALWAYS use CFQUERYPARAM to prevent SQL Injection attacks.
Anyway, this should select all the user email addresses that contain the company name between the "@" and "." characters.  It will also not give false positives when searching for "Dell" and there are email addresses with domains like "silverdell.com" or "delltaco.com".
