oci_commit — 提交未执行的事务处理
说明
bool oci_commit ( resource$connection
)
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。
Example #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。
Note:
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。
Note:
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() 和 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
Example #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
Note:
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.
Note:
In PHP versions before 5.0.0 you must use ocicommit() instead. 在当前版本中，旧的函数名还可以被使用，但已经被废弃并不建议使用。
