Example from the docs:

my $sth = $dbh->prepare("INSERT INTO staff (first_name, last_name) VAL
+UES (?, ?)");
my $tuples = $sth->execute_array(
    { ArrayTupleStatus => \my @tuple_status },
    \@first_names,
    \@last_names,
);
if ($tuples) {
    print "Successfully inserted $tuples records\n";
}
else {
    for my $tuple (0..@last_names-1) {
        my $status = $tuple_status[$tuple];
        $status = [0, "Skipped"] unless defined $status;
        next unless ref $status;
        printf "Failed to insert (%s, %s): %s\n",
            $first_names[$tuple], $last_names[$tuple], $status->[1];
    }
}

It inserts from @first_names and @last_names. You insert from @books.

my $sth = $dbh->prepare("INSERT INTO temp_selectedTitles VALUES (?)");
my $tuples = $sth->execute_array(
    { ArrayTupleStatus => \my @tuple_status },
    \@books,
);
if ($tuples) {
    print "Successfully inserted $tuples records\n";
}
else {
    for my $tuple (0..$#books) {
        my $status = $tuple_status[$tuple];
        $status = [0, "Skipped"] unless defined $status;
        next unless ref $status;
        printf "Failed to insert (%s): %s\n",
            $books[$tuple], $status->[1];
    }
}

Update: There's something buggy with the error reporting. The next will never execute. Does anyone know what they were trying to accomplish?

Update: No, it could still be executed, but it still looks very odd.
