A record is 13 fields, I want to collect a list of uniques in field 6, when field 10 is a certain value, i.e.
SELECT Field6 WHERE Field10 ='RIGHTRECORD'
Test data:
16 records total, I should get 2 uniques, out of 8 records that have the right value in Field10.
my %cons;
my $text;
my $count;

while(<>){
  $text = m/\|(.*?\|){5}(.*?)\|(.*?\|){3}(SNOMEDCT)/;
  if ($text){
    print "$_\n";
  }
  $cons{$2}++;
}
my $count = keys %cons;
print "$count";

my result is one line, "1".
