oci_set_db_operation()

(PHP 7 >= 7.2.14, PHP 7.3.1 > 7.3 PECL OCI8 >= 2.2.0)

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 asV$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
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the operation
oci_set_db_operation($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;

注释

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。
