When, where? What have you tried? :doh:

I guess you want a feature to check if emailid already exists or not in your application. For that, you need to execute a query with the email id and see if count is greater than zero. If so, it exists.

SQL

SELECT COUNT(*) FROM EmailTable WHERE storedEmailIDs = 'checkThisID@Abc.com'

:)Interesting approach but I doubt the OP wanted that. My 5 for the sarcasm though.

1. You should not do this. Instead, inform the user when he enters the email address that verification mail will be sent on the same id and till then do not allow him to do anything on the website.

2. If you are referring to validating email address that it can be a valid email, you are use from a large list on regular expression available on the web.

3. If your website provides the email addresses to the users, like Gmail does, then you must be having a table to store already taken addresses. When the user enters one and submits the form, check if it exists in the database and return appropriate message if it already exists.

You may have noticed the importance of being descriptive while asking the question by now. If you can, update the current question and try to describe your problem next time. :)
