php - MySQL在删除事务失败后不回滚

Question

我正在使用这样的结构:

mysql_query('BEGIN') or die('BEGIN transaction failed!');
$query = "DELETE FROM transaction";

try {
    $result = mysql_query($query);

    if (!$result) {
        throw new Exception('Db error', 1);
    }

    $query = "  INS ERT INTO transaction
                SELECT ....."; // just buggy request
    $result = mysql_query($query);

    if (!$result) {
        throw new Exception('Db error', 1);
    }

    mysql_query('COMMIT') or die('COMMIT transaction failed!');
} catch (Exception $e) {
    mysql_query('ROLLBACK') or die('ROLLBACK transaction failed!');

}

但由于某种原因，“删除”事务没有回滚并且表保持为空。

我错过了什么吗？

Answer 1

MySQL Server (version 3.23-max and all versions 4.0 and above) supports transactions with the InnoDB and BDB

请将表引擎更改为innoDB以支持事务

这是如何更换引擎

ALTER TABLE table_name ENGINE = InnoDB;
