oci_set_client_identifier

(PHP 5.3.2, PECL OCI8 >= 1.4.0)

oci_set_client_identifierSets the client identifier

Beschreibung

bool oci_set_client_identifier ( resource $connection , string $client_identifier )

Sets the client identifier used by various database components to identify lightweight application users who authenticate as the same database user.

The client identifier is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed.

The identifier can subsequently be queried from database administration views such as V$SESSION. It can be used with DBMS_MONITOR.CLIENT_ID_TRACE_ENABLE for tracing. It can be used for auditing.

The value may be retained across persistent connections.

Parameter-Liste

connection

Ein Oracle-Verbindungs-Identifiierer, der von oci_connect(), oci_pconnect(), oder oci_new_connect() zurückgegeben wurde.

client_identifier

User chosen string up to 64 bytes long.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Beispiele

Beispiel #1 Setting the client identifier to the application user

<?php

// Find the application user's login name
session_start();
$un my_validate_session($_SESSION['username']);
$c oci_connect('myschema''welcome''localhost/XE');

// Tell Oracle who that user is
oci_set_client_identifier($c$un);

// The next roundtrip to the database will piggyback the identifier
$s oci_parse($c'select mydata from mytable');
oci_execute($s);

// ...

?>

Anmerkungen

Achtung

Roundtrip Hinweis

Einige, aber nicht alle OCI8-Funktionen verursachen Roundtrips. Roundtrips zur Datenbank dürfen nicht für Queries auftreten, wenn der Ergebniscache aktiviert ist.
