PHP 8.1.15 Released!

oci_commit

(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)

oci_commit提交未执行的事务处理

说明

oci_commit(resource $connection): bool

oci_commit() 将 Oracle 连接 connection 上正在运行的事务中所有未执行的语句提交处理。

示例 #1 oci_commit() 例子

<?php
// Login to Oracle server
$conn = oci_connect('scott', 'tiger');

// Parse SQL
$stmt = oci_parse($conn, "
INSERT INTO
employees (name, surname)
VALUES
('Maxim', 'Maletsky')
"
);

/* Execute statement
OCI_DEFAULT tells oci_execute()
not to commit statement immediately */
oci_execute($stmt, OCI_DEFAULT);

/*
....
Parsing and executing other statements here ...
....
*/

// Commit transaction
$committed = oci_commit($conn);

// Test whether commit was successful. If error occurred, return error message
if (!$committed) {
$error = oci_error($conn);
echo
'Commit failed. Oracle reports: ' . $error['message'];
}

?>

成功时返回 true, 或者在失败时返回 false

注意:

当关闭连接或脚本结束时(看哪个先)事务会自动回卷。需要明确地调用 oci_commit() 来提交事务,或 oci_rollback() 来中止事务。

注意:

在 PHP 5.0.0 之前的版本必须使用 ocicommit() 替代本函数。该函数名仍然可用,为向下兼容作为 oci_commit() 的别名。不过其已被废弃,不推荐使用。

参见 oci_rollback()oci_execute()

参数

connection

An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().

返回值

成功时返回 true, 或者在失败时返回 false

范例

示例 #2 oci_commit() example

<?php

// Insert into several tables, rolling back the changes if an error occurs

$conn = oci_connect('hr', 'welcome', 'localhost/XE');

$stid = oci_parse($conn, "INSERT INTO mysalary (id, name) VALUES (1, 'Chris')");

// The OCI_NO_AUTO_COMMIT flag tells Oracle not to commit the INSERT immediately
// Use OCI_DEFAULT as the flag for PHP <= 5.3.1. The two flags are equivalent
$r = oci_execute($stid, OCI_NO_AUTO_COMMIT);
if (!
$r) {
$e = oci_error($stid);
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

$stid = oci_parse($conn, 'INSERT INTO myschedule (startday) VALUES (12)');
$r = oci_execute($stid, OCI_NO_AUTO_COMMIT);
if (!
$r) {
$e = oci_error($stid);
oci_rollback($conn); // rollback changes to both tables
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

// Commit the changes to both tables
$r = oci_commit($conn);
if (!
r) {
$e = oci_error($conn);
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

?>

注释

注意:

Transactions are automatically rolled back when you close the connection, or when the script ends, whichever is soonest. You need to explicitly call oci_commit() to commit the transaction.

Any call to oci_execute() that uses OCI_COMMIT_ON_SUCCESS mode explicitly or by default will commit any previous uncommitted transaction.

Any Oracle DDL statement such as CREATE or DROP will automatically commit any uncommitted transaction.

注意:

In PHP versions before 5.0.0 you must use ocicommit() instead.
