My standard idiom for this sort of thing goes like this: 
my $rows = $sth->fetchall_arrayref;

for my $row ( @$rows ) {
    my @fields = @$row;
    # do something with @fields...
}

# or, if the per-field activity is pretty dense:
for my $row ( @$rows ) {
    for my $field ( @$row ) {
        # do something with $field...
    }
}

No doubt there are other approaches that some would consider more "elegant" or "clever", but usually when dealing with basic query activity like this, the plain and simple loops with descriptive variable names is just the easiest way.
