( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Thank you very much for the detailed explaining, a more simple, less code needed and straightforward approach that the initail if(...) structure i had in mind

I didn't knew i could pass variables as arguments to $db->do(...) like that, i was under the impression that i only was used when one had a fixed mysql statement with all arguments known (no vars)! If not i was using prepare and execute, i mean in case of unknown variables like '?' for '$pagename'. Can the 'undef' be ommited too as 'statemnt,,@bind_vars' ? The 'undef' is still a mystery to me on what it does although i read the help section.

Another question is that i didnt understand why you uses this version of select:

my ($counter) = $db->selectrow_array( 'SELECT pagecounter FROM counters WHERE pagename = ?', undef, $pagename );
If i wanted to dot he same i would do something like:
my $counter = 'SELECT pagecounter FROM counters WHERE pagename = ?' +, undef, $pagename );
or
my $sth = $db->prepare('SELECT pagecounter FROM counters WHERE pagenam +e = ?'); $sth->execute($pagename);
Why the need for ($counter) and the method $db->selectrow_array ?
