oci_set_module_name
(PHP 5 >= 5.3.2, PHP 7, PECL OCI8 >= 1.4.0)
oci_set_module_name — Sets the module name
说明
oci_set_module_name
( resource $connection
, string $module_name
) : bool
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The name can subsequently be queried from database administration
views such as V$SESSION. It can be used for
tracing and monitoring such as with V$SQLAREA
and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
参数
connection- Oracle 连接标识，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。
module_name- User chosen string up to 48 bytes long.
返回值
成功时返回 true， 或者在失败时返回 false。
注释
Note: Oracle 版本需求
当 PHP 是与 Oracle 数据库 10g 及更新版本的 扩展库链接时，此函数可用。
Tip
使用旧版的 OCI8 或 ORACLE 数据库，可使用
Oracle DBMS_APPLICATION_INFO 包来设置客户端信息。这比使用
oci_set_client_info() 较低效。
Caution 一些 OCI8 函数会导致 Roundtrips. 对数据库来说当启用结果缓存时，查询可能不产生 Roundtrips。
范例
Example #1 Setting the module name
<?php$c = oci_connect('hr', 'welcome', 'localhost/XE');// Record the moduleoci_set_module_name($c, 'Home Page');// Code that causes a round-trip, for example a query:$s = oci_parse($c, 'select * from dual');oci_execute($s);oci_fetch_all($s, $res);sleep(30);?>
// While the script is running, the administrator can see the // modules in use: sqlplus system/welcome SQL> select module from v$session;
