(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_client_info — Sets the client information
說明
bool oci_set_client_info ( resource$connection
, string $client_info
)
Sets the client information for Oracle tracing.
The client information is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed.
The client information can subsequently be queried from database administration views such as V$SESSION.
The value may be retained across persistent connections.
參數
connection
Oracle 連接標識，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。
client_info
User chosen string up to 64 bytes long.
返回值
成功時返回 TRUE， 或者在失敗時返回 FALSE。
范例
Example #1 Setting the client information
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the client information
oci_set_client_info($c, 'My Application Version 2');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the client // information: sqlplus system/welcome SQL> select client_info from v$session;
注釋
Note: Oracle 版本需求
當 PHP 是與 Oracle 數據庫 10g 及更新版本的 擴展庫鏈接時，此函數可用。
Tip性能使用舊版的 OCI8 或 ORACLE 數據庫 ，可使用 Oracle DBMS_APPLICATION_INFO 包來設置客戶端信息。這比使用 oci_set_client_info() 較低效。
CautionRoundtrip Gotcha一些 OCI8 函數會導致 Roundtrips. 對數據庫來說當啟用結果緩存時，查詢可能不產生Roundtrips。
