(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_client_identifier — Sets the client identifier
说明 bool oci_set_client_identifier ( resource $connection , string $client_identifier )Sets the client identifier used by various database components to identify lightweight application users who authenticate as the same database user.
The client identifier is registered with the database when the next &#;roundtrip&#; from PHP to the database occurs, typically when an SQL statement is executed.
The identifier can subsequently be queried, for example with SELECT SYS_CONTEXT(&#;USERENV&#;,&#;CLIENT_IDENTIFIER&#;) FROM DUAL. Database administration views such as V$SESSION will also contain the value. It can be used with DBMS_MONITOR.CLIENT_ID_TRACE_ENABLE for tracing and can also be used for auditing.
The value may be retained across page requests that use the same persistent connection.
参数
connection
Oracle 连接标识，由oci_connect()，oci_pconnect()，或oci_new_connect() 返回。
client_identifierUser chosen string up to bytes long.
返回值成功时返回 TRUE， 或者在失败时返回 FALSE。
范例
Example #1 Setting the client identifier to the application user
<?php//Findtheapplicationuser'sloginnamesession_start();$un=my_validate_session($_SESSION['username']);$c=oci_connect('myschema','welcome','localhost/XE');//TellOraclewhothatuserisoci_set_client_identifier($c,$un);//Thenextroundtriptothedatabasewillpiggybacktheidentifier$s=oci_parse($c,'selectmydatafrommytable');oci_execute($s);//...?> 注释 CautionRoundtrip Gotcha一些 OCI8 函数会导致 Roundtrips. 对数据库来说当启用结果缓存时，查询可能不产生Roundtrips。
