## 直接与数据库交互

如果您想独立于 FastAPI 直接浏览 SQLite 数据库（文件）以调试其内容、添加表、列、记录、修改数据等，您可以使用[SQLite 的 DB Browser](https://sqlitebrowser.org/)

它看起来像这样：

您还可以使用[SQLite Viewer](https://inloop.github.io/sqlite-viewer/)或[ExtendsClass](https://extendsclass.com/sqlite-browser.html)等在线 SQLite 浏览器。

## 中间件替代数据库会话

And you can also declare numeric validations:

* `gt`: `g`reater `t`han
* `ge`: `g`reater than or `e`qual
* `lt`: `l`ess `t`han
* `le`: `l`ess than or `e`qual

/// info

`Query`, `Path`, and other classes you will see later are subclasses of a common `Param` class.

All of them share the same parameters for additional validation and metadata you have seen.

  // so there is no object state put at risk by stopping the threads abruptly. In some cases a test

  // clean up these threads.
