まず、コールバックを追加する前の通常の API アプリがどうなるか見てみましょう。

`Invoice` ボディを受け取り、クエリパラメータ `callback_url` にコールバック用の URL を含める *path operation* を持ちます。

この部分はとても普通で、ほとんどのコードはすでに見覚えがあるはずです:

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[7:11,34:51] *}

/// tip | 豆知識

`callback_url` クエリパラメータは、Pydantic の [Url](https://docs.pydantic.dev/latest/api/networks/) 型を使用します。

        SMBUtil.writeInt4(32, testBuffer, 52); // sub-authority 1
        SMBUtil.writeInt4(544, testBuffer, 56); // sub-authority 2

        int size = securityDescriptor.decode(testBuffer, 0, testBuffer.length);

### Read Heroes { #read-heroes }

We can **read** `Hero`s from the database using a `select()`. We can include a `limit` and `offset` to paginate the results.

### Read One Hero { #read-one-hero }

We can **read** a single `Hero`.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}

### Delete a Hero { #delete-a-hero }

### Hero の取得 { #read-heroes }

`select()` を使ってデータベースから `Hero` を取得できます。結果のページネーションのために `limit` と `offset` を含められます。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[48:55] hl[51:52,54] *}

### 単一の Hero を取得 { #read-one-hero }

単一の `Hero` を取得できます。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}
