php5/oci8/oracle 11g1 insert doesn't work ..updated..sorry

The following code doesn't do the insert.

I've tried the insert statement in a session:

[oracle@LMKIII log_book]$ sqlplus landon/<PW>

require('anyco_ui.inc');

$db = "(DESCRIPTION =

   (CONNECT_DATA =

   )
)";
if ($conn=oci_connect('landon', 'PWD',$db))
{
echo "Successfully connected to Oracle.\n";

}
else
{
$err = OCIError();
echo "Oracle Connect Error " . $err['message'];
}


  $stid = oci_parse($conn, 'insert into log_book values ( TO_DATE('08/12/1973','MM/dd/YYYY'),'B-17','N5787G',1,1.8);');

  $r = oci_execute($stid );

        oci_commit($conn);
        OCILogoff($conn);
echo "end";
?>

produces:  Successfully connected to Oracle.end 


This is my first php/oci8/oracle insert! What could be simpler! HELP!

In desperation, I used em to give myself every possible privilege !

Not good but after it works, I can go back and correct and learn privileges!

I rebooted and tried this again to no avail.

I suspected a commit problem but oci_execute has commit as default!

The table has no primary key defined since no values are unique.

I have a similar table with a row id!
