...e veja como seu editor irá auto-completar os atributos e saberá os tipos:

![editor support](https://fastapi.tiangolo.com/img/vscode-completion.png)

    * **Schnell**: Sehr hohe Leistung, auf Augenhöhe mit **NodeJS** und **Go** (dank Starlette und Pydantic).
    * **Intuitiv**: Hervorragende Editor-Unterstützung. <abbr title="Auch bekannt als automatische Vervollständigung, IntelliSense">Codevervollständigung</abbr> überall. Weniger Zeitaufwand für das Debuggen.

    * **Rápido**: Alta performance, no nível de **NodeJS** e **Go** (graças ao Starlette e Pydantic).
    * **Intuitivo**: Ótimo suporte de editor. <abbr title="também conhecido como auto-complete, auto completação, IntelliSense">_Auto-Complete_</abbr> em todo lugar. Menos tempo _debugando_.
    * **Fácil**: Projetado para ser fácil de usar e aprender. Menos tempo lendo documentações.

!!! note
    FastAPI will know that the value of `q` is not required because of the default value `= None`.

    The `Union` in `Union[str, None]` will allow your editor to give you better support and detect errors.

## Additional validation

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

     * not be set within all security descriptors even though the ACE was in
     * face inherited. If an inherited ACE is added to a parent the Windows
     * ACL editor will rebuild all children ACEs and set this flag accordingly.
     * 
     * @return whether this is an inherited ACE
     */
    boolean isInherited ();


    /**

And then, when using the dependency in a *path operation function*, we declare it with the type `Session` we imported directly from SQLAlchemy.

This will then give us better editor support inside the *path operation function*, because the editor will know that the `db` parameter is of type `Session`:

=== "Python 3.9+"

    ```Python hl_lines="22  30  36  45  51"
    {!> ../../../docs_src/sql_databases/sql_app_py39/main.py!}

But when you declare them with Python types (in the example above, as `int`), they are converted to that type and validated against it.

All the same process that applied for path parameters also applies for query parameters:

* Editor support (obviously)
* Data <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>
* Data validation
* Automatic documentation

## Defaults

     * not be set within all security descriptors even though the ACE was in
     * face inherited. If an inherited ACE is added to a parent the Windows
     * ACL editor will rebuild all children ACEs and set this flag accordingly.
