    ```
    
    #### 注意
    
    参数:
    
    ```Python
    connect_args={"check_same_thread": False}
    ```
    
    ...仅用于`SQLite`,在其他数据库不需要它。
    
    !!! info "技术细节"
    
        默认情况下,SQLite 只允许一个线程与其通信,假设有多个线程的话,也只将处理一个独立的请求。
    
        这是为了防止意外地为不同的事物(不同的请求)共享相同的连接。
    
        但是在 FastAPI 中,普遍使用def函数,多个线程可以为同一个请求与数据库交互,所以我们需要使用`connect_args={"check_same_thread": False}`来让SQLite允许这样。
    
        此外,我们将确保每个请求都在依赖项中获得自己的数据库连接会话,因此不需要该默认机制。

  3. docs/en/docs/tutorial/sql-databases.md

    The argument:
    
    ```Python
    connect_args={"check_same_thread": False}
    ```
    
    ...is needed only for `SQLite`. It's not needed for other databases.
    
    !!! info "Technical Details"
    
        By default SQLite will only allow one thread to communicate with it, assuming that each thread would handle an independent request.
    
        This is to prevent accidentally sharing the same connection for different things (for different requests).
