transfer image from mysql to oracle

[smgv13]

Hi Guys,
This is part of my code When I run my whole program I get this warning
OCI-Lob::save()[function.save]😮RA-22990: LOB locators cannot span transactions

the value of row[1] is coming from mysql.

$temp_picture=$row[1];
$pict_image=oci_new_descriptor($conn,OCI_D_LO😎;

   $oracle_query="insert into card(id,picture) VALUES (:id,empty_blob()) returning picture into :pict";


    $stid=oci_parse($conn, $oracle_query);
    oci_bind_by_name($stid,':id',$temp_suid);

   oci_bind_by_name($stid,':pict',$pict_image,-1,OCI_B_BLOB);



   $r=oci_execute($stid);
     if ($r)
    {
    print "One Row Inserted \n";
  $pict_image->save($temp_picture);
    }

Could you please double check the last line if the command is correct
Thank you
