oci_new_descriptor - Initializes a new empty LOB or FILE descriptor

OCI-Lob oci_new_descriptor (resource $connection, [int $type = OCI_DTYPE_LOB]) DESCRIPTION
Allocates resources to hold descriptor or LOB locator. PARAMETERS
o $connection - An Oracle connection identifier, returned by oci_connect(3) or oci_pconnect(3). o $type - Valid values for $type are: OCI_DTYPE_FILE, OCI_DTYPE_LOB and OCI_DTYPE_ROWID. RETURN VALUES
Returns a new LOB or FILE descriptor on success, FALSE on error. EXAMPLES
Example #1 oci_new_descriptor(3) example <?php /* This script is designed to be called from a HTML form. * It expects $user, $password, $table, $where, and $commitsize * to be passed in from the form. The script then deletes * the selected rows using the ROWID and commits after each * set of $commitsize rows. (Use with care, there is no rollback) */ $conn = oci_connect($user, $password); $stmt = oci_parse($conn, "select rowid from $table $where"); $rowid = oci_new_descriptor($conn, OCI_D_ROWID); oci_define_by_name($stmt, "ROWID", $rowid); oci_execute($stmt); while (oci_fetch($stmt)) { $nrows = oci_num_rows($stmt); $delete = oci_parse($conn, "delete from $table where ROWID = :rid"); oci_bind_by_name($delete, ":rid", $rowid, -1, OCI_B_ROWID); oci_execute($delete); echo "$nrows "; if (($nrows % $commitsize) == 0) { oci_commit($conn); } } $nrows = oci_num_rows($stmt); echo "$nrows deleted... "; oci_free_statement($stmt); oci_close($conn); ?> <?php /* This script demonstrates file upload to LOB columns * The formfield used for this example looks like this * <form action="upload.php" method="post" enctype="multipart/form-data"> * <input type="file" name="lob_upload" /> * ... */ if (!isset($lob_upload) || $lob_upload == 'none'){ ?> <form action="upload.php" method="post" enctype="multipart/form-data"> Upload file: <input type="file" name="lob_upload" /><br /> <input type="submit" value="Upload" /> - <input type="reset" value="Reset" /> </form> <?php } else { // $lob_upload contains the temporary filename of the uploaded file // see also the features section on file upload, // if you would like to use secure uploads $conn = oci_connect($user, $password); $lob = oci_new_descriptor($conn, OCI_D_LOB); $stmt = oci_parse($conn, "insert into $table (id, the_blob) values(my_seq.NEXTVAL, EMPTY_BLOB()) returning the_blob into :the_blob"); oci_bind_by_name($stmt, ':the_blob', $lob, -1, OCI_B_BLOB); oci_execute($stmt, OCI_DEFAULT); if ($lob->savefile($lob_upload)){ oci_commit($conn); echo "Blob successfully uploaded "; }else{ echo "Couldn't upload Blob "; } $lob->free(); oci_free_statement($stmt); oci_close($conn); } ?> Example #2 oci_new_descriptor(3) example <?php /* Calling PL/SQL stored procedures which contain clobs as input * parameters (PHP 4 >= 4.0.6). * Example PL/SQL stored procedure signature is: * * PROCEDURE save_data * Argument Name Type In/Out Default? * ------------------------------ ----------------------- ------ -------- * KEY NUMBER(38) IN * DATA CLOB IN * */ $conn = oci_connect($user, $password); $stmt = oci_parse($conn, "begin save_data(:key, :data); end;"); $clob = oci_new_descriptor($conn, OCI_D_LOB); oci_bind_by_name($stmt, ':key', $key); oci_bind_by_name($stmt, ':data', $clob, -1, OCI_B_CLOB); $clob->write($data); oci_execute($stmt, OCI_DEFAULT); oci_commit($conn); $clob->free(); oci_free_statement($stmt); ?> NOTES
Note In PHP versions before 5.0.0 you must use ocinewdescriptor(3) instead. This name still can be used, it was left as alias of oci_new_descriptor(3) for downwards compatability. This, however, is deprecated and not recommended. SEE ALSO
