You must be kidding, sundialsvc4. Using a database for such a simple task is just plain overkill. You can obtain the desired result with just a simple Perl one-liner:

$ cat  test_file.txt
Name1 1234
Name2 9999
Name1 5514
Name3 5415
Name2 6419

$ perl -ne 'my ($key, $val) = split; $hash{$key} .= " $val"; END { pri
+nt "$_ => $hash{$_} \n" for keys %hash;}' test_file.txt
Name3 =>  5415
Name1 =>  1234 5514
Name2 =>  9999 6419

The result is there even before you start populating your database.
