	// "When using an API to create a directory, the specified
	// path cannot be so long that you cannot append an 8.3 file
	// name (that is, the directory name cannot exceed MAX_PATH

SQL database (you can learn more about SQL primary keys in the SQLModel docs).

    **Note:** We use `int | None` for the primary key field so that in Python code we can *create an object without an `id`* (`id=None`), assuming the database will *generate it when saving*. SQLModel understands that the database will provide the `id` and *defines the column as a non-null `INTEGER`* in the database schema. See [SQLModel docs on primary keys](https://sqlmodel.tiangolo.com/tutorial/create-db-and...
