SQL View Using The CASE Try To Find The @

have created a view in MS SQL2000 as followed:

Select order_NO, shiptoname, Shiptoaddress, Shiptocity,shiptostate, shiptozip,
EMAILaddress
FROM orders;

my question is: If the email @ sign exist in the EMAILaddress column then I need to have a Y show in another column called EMAILflag, if the @ sign does not exist then I would need the EMAILflag to be a N.

This what I have but the emailaddress column is not always null it just has spaces in the field.
Select order_NO, shiptoname, Shiptoaddress, Shiptocity,shiptostate, shiptozip,
EMAILaddress, CASE WHEN emailaddress IS NULL THEN 'N' ELSE 'Y' END AS emailflag
FROM orders;

Any HELP would be GREAT.
Thank You!!
