ocinewdescriptor — Initialize a new LOB descriptor


string ocinewdescriptor(connection[, type]);
int connection: Connection identifier
int type (optional): LOB type


New descriptor or FALSE on error


Allocates a descriptor or a LOB locator. The type parameter can be one of OCI_D_FILE, OCI_D_LOB or OCI_D_ROWID.

Once a new descriptor has been made, methods can be used to perform actions on the LOB. For LOB descriptors the load, save, and savefile can be used. For BFILE descriptors, only the load method can be used.


Since versions 3.0.7 and 4.0


Example 867. Insert and select a binary file

if (!$db = @ocinlogon("dev","dev", "ORCL")) {
    $error = ocierror();
    printf("There was an error connecting. Error was: %s", $error["message"]);

$file = "test.png";

$stmt = ociparse($db,"INSERT INTO gtest VALUES (1,EMPTY_BLOB()) RETURNING id,blobfield INTO :id,:lob");
$lob = ocinewdescriptor($db);
$lob->save(`cat $file`);


$sql = "select blobfield from gtest where id=1";
$stmt = ociparse($db, $sql); 
ociexecute($stmt, OCI_DEFAULT); 
ocifetchinto($stmt, &$row, OCI_RETURN_LOBS); 

header("Content-type: image/png");
echo $row[0];
