### 경로 작동 함수

경로 작동 함수를 `async def` 대신 일반적인 `def`로 선언하는 경우, (서버를 차단하는 것처럼) 그것을 직접 호출하는 대신 대기중인 외부 스레드풀에서 실행됩니다.

만약 상기에 묘사된대로 동작하지 않는 비동기 프로그램을 사용해왔고 약간의 성능 향상 (약 100 나노초)을 위해 `def`를 사용해서 계산만을 위한 사소한 *경로 작동 함수*를 정의해왔다면, **FastAPI**는 이와는 반대라는 것에 주의하십시오. 이러한 경우에, *경로 작동 함수*가 블로킹 <abbr title="Input/Output: 디스크 읽기 또는 쓰기, 네트워크 통신.">I/O</abbr>를 수행하는 코드를 사용하지 않는 한 `async def`를 사용하는 편이 더 낫습니다.

该文件`__init__.py`只是一个空文件，但它告诉 Python `sql_app` 是一个包。

现在让我们看看每个文件/模块的作用。

## 安装 SQLAlchemy

首先你需要安装`SQLAlchemy`:

<div class="termy">

```console
$ pip install sqlalchemy

---> 100%
```

</div>

## 创建 SQLAlchemy 部件

让我们转到文件`sql_app/database.py`。

### 导入 SQLAlchemy 部件

```Python hl_lines="1-3"
{!../../docs_src/sql_databases/sql_app/database.py!}
```
