slayedbylucifer has asked for the
wisdom of the Perl Monks concerning the following question:
I am fetching two columns from oracle DB using the DBD::Oracle module. this is my code whihc Actually fetches the output:
I have omitted rest of the code but above while loop should get you the idea what I am trying to do. "$query" value was given to me by the Oracle DBA and it is fairly complicated as it does quite a few comparisons. BTW, i dont udnertand how that query is wirtten.

So, How to sort these entries and make them unique. I mean above, above duplicate entries should look like below:
please guide me on a technique which can be used in above "while" Loop. In bash, it is fairly simple to run ...| sort | uniq . but I could not find a way in perl to do the same
