在magento安装中从php文件运行自定义sql

我对magento非常陌生，并尝试运行自定义sql查询。但它不是在运行。我包括了所有需要的mage文件，它给出了错误

致命错误：当不在对象上下文中时使用$this

我的查询文件内容

请发表评论，如果你遇到进一步的错误我的问题是我做了一个扩展使用magento扩展创建者。我复制了文件，但仍然没有运行。我发现没有创建任何数据库表。只有这个文件能做到这一点。我正在尝试运行这个文件，这样我的数据库表就可以创建了，我得到了一个解脱，因为它真的超过了25个小时，我被困在这里了。你是在你的模块sql文件上执行这个吗？当我试着安装那个模块时，它没有运行。这个文件是唯一剩下的东西。我正在尝试将其作为一个独立的服务器运行。我在本地服务器上进行了一些更改，我认为它可以为您工作
