Heck, why do extra work when DBI already does it for you?

  @dept = @{$sth->fetchall_arrayref()};

Now @dept holds a bunch of array references, one for each of your rows. You can step through @dept, dereference the array reference, and go to town on the columns you need:

  use strict;
  use Data::Dumper;
  foreach my $thisrow (@dept) {
    if (ref($thisrow) eq 'ARRAY) {
      my @columns = @{$thisrow};
      foreach (@columns) {
        # do something
      }
    }
    else {
      print "Hey!  That's not an array reference!\n";
      print Dumper($thisrow);
    }
  }

Admittedly, that is a little more explicit than I would actually do in practice -- no need for @columns when you can just talk about $thisrow->[2], for example.
