oci_set_db_operation
(PHP 7 >= 7.2.14, PHP 8, PHP 7 >= 7.3.1, PHP 8, PECL OCI8 >= 2.2.0)
oci_set_db_operation — Sets the database operation
說明
$connection, string $action): boolSets the DBOP for Oracle tracing.
The database operation name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when a SQL statement is executed.
The database operation can subsequently be queried from database administration
views such as V$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).
參數
-
connection -
Oracle 連線標識，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。
-
action -
User chosen string.
返回值
成功時返回 true， 或者在失敗時返回 false。
範例
示例 #1 Setting the DBOP
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the operation
oci_set_db_operation($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;
註釋
Roundtrip Gotcha
一些 OCI8 函式會導致 Roundtrips. 對數據庫來說當啟用結果快取時，查詢可能不產生 Roundtrips。
