oci_set_db_operation — Sets the database operation
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).

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;
OCI8 関数の中には、データベースとのやりとりを伴わないものもあります。 たとえば、結果のキャッシングが有効になっている場合、 クエリを実行してもデータベースとのやりとりを行わない可能性があります。
