oci_set_client_info()

(PHP 5 >= 5.3.2, PHP 7, PECL OCI8 >= 1.4.0)

Sets the client information

说明

oci_set_client_info(resource $connection,string $client_info): bool

Sets the client information for Oracle tracing.

The client information is registered with the database when the next 'round-trip' 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 asV$SESSION.

The value may be retained across persistent connections.

参数

$connection: Oracle 连接标识，由oci_connect()，oci_pconnect()，或oci_new_connect()返回。
$client_info: User chosen string up to 64 bytes long.

返回值

成功时返回TRUE，或者在失败时返回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 round-trip, 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;

注释

Note:Oracle 版本需求
当 PHP 是与 Oracle 数据库 10g 及更新版本的扩展库链接时，此函数可用。

Tip

性能

使用旧版的 OCI8 或 ORACLE 数据库，可使用 OracleDBMS_APPLICATION_INFO包来设置客户端信息。这比使用oci_set_client_info()较低效。

Caution

Roundtrip 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。
