    Could you give an actual code example, i'm not sure what you're saying. It appears from the MySQL documentation that the ENCODE function requires 2 parameters, but you haven't mentioned that. Anyway, likely the best way is to just connect to MySQL and perform the operation, for example:

    use strict; use warnings; use DBI; my $dsn = 'DBI:mysql:host=localhost'; my $dbh = DBI->connect($dsn); my $sth = $dbh->prepare("SELECT DECODE('encodedcontent', 'secretvalue' +)"); $sth->execute; my $decoded = $sth->fetchrow; print $decoded;
      There is problem: SELECT ENCODE('test','test') returns ? but SELECT DECODE('?','test') doesn't return test but ttZ what is wrong ?

        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
