hi monks,

i've written the following code which basically joins two the data from two mysql tables based on an id in the first table.
        my $join = 'customer_id';
        my $sth = $global{DBH}->prepare(" select * from voice_calls ")
+;
        my $cth = $global{DBH}->prepare(" select * from customers wher
+e $join=?");
        $sth->execute();
        while ( my $call = $sth->fetchrow_hashref() ) {

                $cth->execute( ${$call}{$join} );
                my $customer = $cth->fetchrow_hashref();
                $cth->finish;

                foreach my $key (keys %$customer) {
                        ${$call}{$key} = ${$customer}{$key}
                } # end-foreach

                push(@{$self->{RESULTS}}, \%{$call});

        } # end-while
        $sth->finish;

i'm pretty sure there is a way to do this straight from a select in mysql and was wondering if anybody knew it?

cheers,
