## 主**FastAPI**应用程序

现在在`sql_app/main.py`文件中 让我们集成和使用我们之前创建的所有其他部分。

### 创建数据库表

以非常简单的方式创建数据库表：

//// tab | Python 3.9+

```Python hl_lines="7"
{!> ../../docs_src/sql_databases/sql_app_py39/main.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="9"
{!> ../../docs_src/sql_databases/sql_app/main.py!}
```
