oci_commit
(PHP 5, PHP 7, 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。
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_SUCCESSmode explicitly or by default will commit any previous uncommitted transaction.Any Oracle DDL statement such as
CREATEorDROPwill automatically commit any uncommitted transaction.
Note:
In PHP versions before 5.0.0 you must use ocicommit() instead.
