Thank you once again for the explanation! I still though have some unclear parts which i dont understand.

When i do this: 

   my $counter = 'SELECT pagecounter FROM counters WHERE pagename = ?'
+,
      undef, $pagename;

I'm actually expecting one single item for return and NOT an entire array. For example iam expecting 1 filed only (pagecounter that is) that will hold lest say number 75. This is one number so it seems logical to me to store it on a single variable, so i dont get why the baove aint working.

In your response you are saying and semantically (assigning that list to the $counter variable isn't going to help you get the counter from the DB, is it?): Why you say list? i think iam expecting an item only not a bunch of items(list)

Also: 

my ($counter) = $db->selectrow_array(
   'SELECT pagecounter FROM counters WHERE pagename = ?', 
   undef, $pagename);

If for some reason we expect an array why doesn't the following code work as well? I'm considering that 'list' and 'array' are the same thing, both are a bunch of values, right?: 
my @counter = $db->selectrow_array(
   'SELECT pagecounter FROM counters WHERE pagename = ?', 
   undef, $pagename);

What exactly is the difference between ($counter) and @counter ?

And the last thing is that i dont understand although you tried to expalin it to me the use of method 'selectrow_array'. Is it really necessary to tell it we are grabbing an array? doesn't the 'select' do this by its own?

As you can see i'am really confused....

ps. When i want to print variable counter i do 'print $counter' or 'print ($counter)' ?
