Oracle SQL parallel query within PERL

[jbrizu2]

Hello - I am trying to run an oracle parallel query within a perl script but it will not work. I am getting the following error: ORA-24373: invalid length specified for statement (DBD ERROR: OCIStmtPrepare)
I would appreciate any sugguestions on what to try in order to get this to work.

sub cre_mob_arch_tmp {
  print "  (*) Creating Base of Mobility Trouble_Ticket_Archive Tickets ...\n";
  $sql_statement = `
     Create table mob_arch_tmp as select /*+ PARALLEL(a 8) */ * from trouble_ticket_archive@mobility a where to_char((TO_DATE('1970-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')+NUMTODSINTERVAL("CLOSED_TIME"-14400,'second')), 'DD-MON-YY') = to_char(sysdate-1, 'DD-MON-YY')
/
  `;

  unless ($rows = $dbh->do("$sql_statement")) {
    &programError("Could not create table MOB_ARCH_TMP", "$sql_statement", "$DBI::errstr", "dba", "jbriz");
    $dbh->rollback;
    &logoffOracle($dbh);
    exit;
  }
} # sub cre_mob_arch_tmp
