Dear Monks

I am not familar with perl. I need to insert (and sometimes update) a lot of records in bulk to mysql. I want to do them in a multi insert transaction block for speed so that the indexes are only updated once after all inserts. I have looked up how to do this in perl and I would just like to check the code I have found actually does what i think it does and will perform the inserts/updates as i hope 

Listing D
#!/usr/bin/perl

use DBI;

# create database connection
my $dbh = DBI->connect("DBI:mysql:database=somedb;host=localhost", "us
+er", "pass", {'RaiseError' => 1, 'AutoCommit' => 0});

# trap errors using eval{}

my $insert_sth = $db->prepare("insert into table (field) values(?)");
eval {
    
    #go around some loop to get a value
    for 1...100000 {
        $insert_sth->execute($_);
   }
  
    # commit changes
    $dbh->commit();
};

# any errors
# rollback
if ($@) {
    print "Transaction aborted: $@";
    $dbh->rollback();
}

# close connection
$dbh->disconnect();

This is a trivial example but i hope it does what i am intending?

Many thanks
