My code works but I am not sure if I am over doing it or if there would be a better and more straight forward way to accomplish the same thing more efficiently.

Your subroutine takes no parameters, so no variation is possible. In other words, why waste time generating this at runtime, the returned array is constant, so make it so:

use constant DB_DATES => [ qw[
  file_name_201212
  file_name_201301
  file_name_201302
  file_name_201303
  file_name_201304
  file_name_201305
  file_name_201306
  file_name_201307
  file_name_201308
  file_name_201309
  file_name_201310
  file_name_201311
] ];

print for @{ DB_DATES() };;
file_name_201212
file_name_201301
file_name_201302
file_name_201303
file_name_201304
file_name_201305
file_name_201306
file_name_201307
file_name_201308
file_name_201309
file_name_201310
file_name_201311
