I'm encountering strange errors when using placeholders in an sql query, using an Oracle database. For example this query gives me 

DBD::Oracle::db prepare failed: ORA-00907: missing right parenthesis (
+DBD ERROR: error possibly near <*> indicator at char 114 in '    sele
+ct
        (FROM_TZ(
            CAST(sysdate as timestamp)
            ,
            :timezone
        ) <*>AT TIME ZONE :timezone ) AS MY_RESULT
    from dual ...

This is the code I use: 

use strict;
use warnings;
use DBI;

my $sid='MYDB';
my $user='myuser';
my $pass='mypass';

my $dbh = DBI->connect("dbi:Oracle:$sid", $user, $pass,
                         { AutoCommit => 0, RaiseError => 0, PrintErro
+r => 1 } );
my $sth= $dbh->prepare(<<SQL) or die $dbh->errstr;
    select
        (FROM_TZ(
            CAST(sysdate as timestamp)
            ,
            :TIMEZONE
        ) AT TIME ZONE :TIMEZONE ) AS MY_RESULT
    from dual
SQL

$sth->bind_param(':TIMEZONE', 'Europe/Berlin') or die $dbh->errstr;

When I replace ":TIMEZONE" with the string "'Europe/Berlin'", it works, so it is not an issue of the query itself.

In the real production code I use, the error is even more strange, as it tells me something about illegal relational operators.

Is this behaviour somewhere documented in DBD::Oracle? I couldn't find it.

Thanks for your help.
