It helps us help you if you can say what's not working, e.g. what error message is perl giving you when you try to execute the code. That said, there are a couple of things that jumped out at me:

• foreach my $row_ref ... but inside the loop, you're referencing a thing you think is an array reference with the name row_ary; if you're using strict, this should be caught at compile time.
• you're getting an error message that looks like Not an ARRAY reference at your foreach line, because @$object->method treats $object as an array reference

(Also, what you probably meant to write ( @{$DataOut->fetchrow_array} ) won't work either, because fetchrow_array returns the row's data as an array.

So the following loop rewrite should help you get over the two problems I've mentioned:

  while ( my @row = $DataOut->fetchrow_array ) {
      my $fname = $row[0];
      # ...
  }

An even better solution, IMO, would be to use fetchrow_hashref so the columns have readable names and you don't have to go back to the SQL to figure out which column maps onto which variable.
