While Perl has many cases of DWIM (Do What I Mean), there is no deduplicate function either in the core (see perldoc -f deduplicate) nor in the DBI module (see the documentation there). So it might help if you were more specific about what the exact problem is, what methods are available to you and what the intended action and result are.

For example, your situation might be that you have a column in your database that should be unique, let's call this row the customer number. But as the database didn't know about this, there are now several customers with the same customer number. There are also several rows for the same customer with the same customer number.

What approach would be correct in your business logic to resolve these problems ?

There is also a very good meta-hint I can give you, How (Not) To Ask A Question.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ; # The $d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider ($c = $d->accept())->get_request(); $c->send_response( new #in the HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' # web
