Hi All, I am trying to have a script that uses DBI & sqlite. Task at hand is to take data files and check if record exist in db already, if not insert into db table. Problem is it is taking for ever and moving slow. This is my first attempt at the sqlite & Perl. Below is my code if someone can tell me what I am doing wrong or advise how to achieve better performance, I would be grateful. 

my $dbh = DBI->connect(
    "dbi:SQLite:dbname=SSBHLD2.db",
    "",
    "",
    { RaiseError => 1 },
) or die $DBI::errstr;
   $dbh->do("CREATE TABLE IF NOT EXISTS HLDdata(Data TEXT)");




while(<IN>){
   $line = $_;
   my $sth = $dbh->prepare( "select count(*) from HLDdata where Data =
+ '$line'");
   $sth->execute();
   my ($data) = $sth->fetchrow();
   print "$data \n";

   if ($data ne 0){
      print "record exist not adding\n";
      &Logit("record exist not adding");
   }else{
      $dbh->do("INSERT INTO HLDdata(Data) VALUES ('$line')");
      $line =~s/\|/\t/g;
      print "$line\n";
      print OUT "$line";
   }

}
close(IN);
close(OUT);
