    Really can't say. Maybe a character encoding problem if you're copy-and-pasting. The following code works here:

    use strict; use warnings; use DBI; my $db = DBI->connect('DBI:mysql:host=localhost'); my ($encoded) = $db->selectrow_array("SELECT ENCODE('ToBeHidden', 'sec +retvalue')"); my ($decoded) = $db->selectrow_array("SELECT DECODE('$encoded', 'secre +tvalue')"); print $decoded; # prints --> ToBeHidden
      Yes, my mistake I copied binary string, shame ;) Thanks for help.
