【问题描述】：
我正在开发自定义 Magento 扩展程序。我正在开发 Magento 1.9.0.1 版本的扩展。
所以我有一个简单的问题。
我创建了一个扩展，最近我对其进行了一些升级。 扩展的第一个版本编号：1.0.0
让我给你看一下扩展的配置文件：

<smsprice_name>SMS Notification</smsprice_name>

</smspricegroup>
</vivas>
</default>
</config>
并且位于 /app/code/community/VivasIndustries/SmsNotification/sql/smsnotification_setup/mysql4-install-1.0.0.php 的 sql 安装程序文件包含：
<?php
$installer=$this;
$installer->startSetup();
$installer->run("
CREATE TABLE IF NOT EXISTS `VivasIndustries_SmsNotification` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`state` varchar(500) NOT NULL,
`smstext` varchar(500) NOT NULL,
PRIMARY KEY (`id`),
KEY `id` (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
CREATE TABLE IF NOT EXISTS `VivasIndustries_SmsHistory` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`receiver` varchar(500) NOT NULL,
`phone` varchar(500) NOT NULL,
`email` varchar(500) NOT NULL,
`smstext` text NOT NULL,
`date` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
");
$installer->endSetup();
?>
但在升级后我必须将这个想法添加到 MySQL：
$installer->addAttribute("quote_address", "smsprice_total", array("type"=>"varchar"));
$installer->addAttribute("order", "smsprice_total", array("type"=>"varchar"));
那么我怎样才能创建一个升级文件，这个扩展又如何知道它有一个升级呢？
我什至不确定我的问题是否正确。
附：
我将导出 Magento 的整个 MySQL 数据库以搜索匹配项：smsprice_total，这样我就可以确定它们已创建。
谢谢！
