You should be using strict. I think $q.="$key, "; should be $query.="$key, ";

update: and you're creating a new lexical variable $query within the if ($action eq ..., which goes out of scope. 

my $query;
if ($action eq 'Problem Submit')        
  $query = "INSERT INTO Ticket_Data (";

  for  $key ( keys %ORA_MAPPING ) {
     my $value = $ORA_MAPPING{$key};
     next if $key eq "Data_id";
     $query.=" $value, "; # or did you really mean $key here?
  }

Also note that you should be careful if you build queries from external/dynamic input. Use placeholders if you can, and DBI->quote otherwise.
