IN Magento如何在单个事务中的多个表中插入数据，如果进程中有任何错误，则回滚。我可以编写自定义查询并使用事务，但我更愿意，如果我可以使用Magento方法。

Magento Database Transaction 操作代码如下：

$connection = Mage::getSingleton('core/resource')->getConnection('core_write');
try {
    $connection->beginTransaction();

    // Make saves and other actions that affect the database

    $connection->commit();
} catch (Exception $e) {
    $connection->rollback();
}

下面是magento事务的案例

$connection = Mage::getSingleton('core/resource')->getConnection('core_write');

try {
    $connection->beginTransaction();
    $model = Mage::getModel('sales/order_creditmemo')->load($id);
    $model->setNewOrderId($incrementId);
    $model->setStoreCreditUsed($store_credit_used);
    $query = $model->save();

    $historyModel = Mage::getModel('amstcred/balanceHistory')->load($historyId);
    $historyModel->setIsRelationOrder(1)->save();

    $connection->commit();
} catch (Exception $e) {
    $connection->rollback();
}
