Ok, I've got the command returning the contents of the whole CSV file. The question now is how do I locate, one specific row and affect it's data? Here's what I have:

#!/usr/bin/perl -w
use strict;
use DBI;
use File::Basename;

my $dir   = '.';
my $file  = 'memberlist.csv';
my $table = (fileparse($file,'.csv'))[0]; 
my $cols  = [qw(Username Email Posts EmailSet Group Unknown Date Times
+tamp Password MD5)];
my $sep   = ',';

my $dbh = DBI->connect(
   "DBI:CSV:f_dir=$dir;csv_eol=\n;csv_sep_char=$sep;",
   {RaiseError=>1},);

$dbh->{csv_tables}->{$table} = { 
   file      => $file,
   col_names => $cols,};

    my $sth = $dbh->prepare("SELECT Username, Email, Posts, Timestamp 
+FROM memberlist");
    $sth->execute() or die "Cannot execute: " . $sth->errstr();

    while ( ( my $Username, my $Email, my $Posts, my $Timestamp) = $st
+h->fetchrow_array) {
            print "$Username, $Email, $Posts, $Timestamp\n";
    }

$sth->finish();

Now I tried an 'if' command within the 'while' statement to match up an email, then increment it's '$post' variable once it hit a specified address (a test of the function I need to do) and all it did was increment everyone's post count. At this point, I wonder if I'm on the right track. Should I even be pulling the value into the script, or should I be looking at an 'update' command of some sort? I've read elsewhere that someone just read each line into an array and went from there, but that sounds like a lot of overhead to read it each time. Likewise, I'd be concerned about holding the whole table in memory in the event of an error during the process.
