Re^3: Check For Dupes In FLat DB Before Adding

[pileofrogs]

Okay, to further refine my understanding of your question:

You say you're trying to eliminate duplicate emails. You also say you're trying to add email in places where there isn't one before. Those sound like two different things.

When you say duplicate emails, do you mean that no 2 records should have the same email? Or do you mean that no record should have 2 emails?

When you're adding an email to records that don't already have one, are you adding the same email over and over (causing duplicates) or do you have a list of emails to add?

Maybe it would be easiest if you posted a chunk of your flat file DB as a 'before' and 'after', with the 'after' section manually fixed.

Hi pileofrogs, What I'm trying to do is the following...allow users to add themselves to a flat database which looks like this(split with an "=" sign):

[e-mail]=users name 1
[e-mail]=users name 2
[e-mail]=users name 3
[e-mail]=users name 4

If a user tries to add themselves, using an email address that already exists in the database, then they are told to use a different email....If the email doesn't exist in the database then the email and name are added.
