I really need the help of the Perl/Oracle gurus out there :( I have this program that is trying to do an insert on a table that has two TIMESTAMP fields. Here's the consolidated code:

use strict;
use DBI;

$ENV{'ORACLE_HOME'} = '/pkg/oracle/client10g';

my $sid = 'mysid';
my $user = 'joe';
my $pass = 'joespw';

my $dbh = DBI->connect( "dbi:Oracle:$sid", "$user", "$pass" )
    || die( $DBI::errstr . "\n" );
$dbh->{AutoCommit}    = 0;
$dbh->{RaiseError}    = 1;
$dbh->{ora_check_sql} = 0;
$dbh->{RowCacheSize}  = 16;

my $sql = qq{insert into reservation (machinename,reservationida,begin
+reserve,endreserve,description,reservationid) values (?,?,TO_TIMESTAM
+P(?,'DD/MON/YYYY HH:MI:SS'),
TO_TIMESTAMP(?,'DD/MON/YYYY HH.MI.SS'),?,?)};

my $sth = $dbh->prepare($sql);

$sth->bind_param(1, 'volcano');
$sth->bind_param(2, 666);
$sth->bind_param(3, '12/MAR/2010 7:20:00');
$sth->bind_param(4, '12/MAR/2010 8:20:00');
$sth->bind_param(5, 'This machine tends to explode!');
$sth->bind_param(6, 666);

#print "$sql\n";

$sth->execute;
$sth->finish;
$dbh->disconnect;

The database table:

Here are 2 normal rows from a select statement:

CARRIE,123454,24-NOV-09 06.00.00.000000 PM,24-NOV-09 08.00.00.000000 P

When I run my script, I get:

DBD::Oracle::st execute failed: ORA-02291: integrity constraint (LRRS.
+RESERVATION_MACHINE_FK1) violated - parent key not found (DBD ERROR: 
+OCIStmtExecute) [for Statement "insert into reservation (machinename,

This error actually appears twice.

I can connect using sqlplus and insert manually, kind of like this: http://use.perl.org/~jdavidb/journal/29951, so it seems TO_TIMESTAMP should work - actually I'm not even sure if that's the problem. Can't seem to figure this one out... thanks for the help!
