Hi, monks

In my Perl code, I am now using DBIx::Simple to connect with my Database.. To update a bunch of records saved in a file, I just loop through each line in the file and update records one by one. 

..[skip]..
while (my $record = <$input>)
{
    chomp $record;
    my ($val1, $val2, $val3) = (split(/\|/,$record))[1,3,5];
    my %data = (
       va => $val1,
       vb => $val2,
    );
    my %where = (
        vc => $val3,
    );
    $dbh->update('myTable', \%data, \%where);
}

This works quite slow. Is there any better way in DBIx::Simple or any other easy-to-use DBI ways/models to implement fast update of many records(i.e. 150K records, the table contains totally 200K records). thanks..
