oci_set_db_operation
(PHP 7 >= 7.2.14, PHP 7 >= 7.3.1, PECL OCI8 >= 2.2.0)
oci_set_db_operation — Sets the database operation
说明
oci_set_db_operation
( resource $connection
, string $dbop
) : bool
Sets the DBOP for Oracle tracing.
The database operation name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when a SQL statement is executed.
The database operation can subsequently be queried from database administration
views such as V$SQL_MONITOR
.
The oci_set_db_operation() function is available when OCI8 uses Oracle 12 (or later) Client libraries and Oracle Database 12 (or later).
参数
connection
- Oracle 连接标识,由 oci_connect(),oci_pconnect(),或 oci_new_connect() 返回。
dbop
- User chosen string.
返回值
成功时返回 true
, 或者在失败时返回 false
。
范例
Example #1 Setting the DBOP
<?php$c = oci_connect('hr', 'welcome', 'localhost/XE');// Record the operationoci_set_db_operation($c, 'main query');// Code that causes a round-trip, for example a query:$s = oci_parse($c, 'select * from dual');oci_execute($s);oci_fetch_all($s, $res);sleep(30);?>
// While the script is running, the administrator can see the database operations // being performed: sqlplus system/welcome SQL> select dbop_name from v$sql_monitor;
注释
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。
