RE: Order by email address by domain ?

here's an idea:

if you would have all emails stored in the reverse order:
moc.niamod@resu

then all you would need is simple 'ORDER BY email'.

Also, in this way, emails like user@subdomain.domain.com would be perfectly
ordered.

Is that a crazy thought?

If not yet then: why not to add an additional field to the table with the
reverse domain only? (after an @) ordering by it. INDEX would also be
simple.

now is crazy? Then, is there any such function in PostgreSQL? With C it
would be so easy and fast.

Cheers!

Hi,

I just want to order by a listing of email address by domain like :

toto@aol.com
tutu@aol.com
toto@be.com

Is it possible and how ?

Thanks !
