ここでは `SessionDep` 依存関係（`Session`）を使って、新しい `Hero` を `Session` インスタンスに追加し、データベースにコミットし、`hero` のデータをリフレッシュしてから返します。

### 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[40:45] hl[40:45] *}

這裡我們使用 `SessionDep` 依賴（即一個 `Session`），把新的 `Hero` 加入 `Session` 實例，提交變更到資料庫，刷新 `hero` 的資料，然後回傳它。

### 讀取多個 Hero { #read-heroes }

我們可以用 `select()` 從資料庫「讀取」多個 `Hero`。可以加入 `limit` 與 `offset` 來分頁。

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

### 讀取單一 Hero { #read-one-hero }

我們可以「讀取」單一的 `Hero`。

For deployments with [Site Replication](https://docs.min.io/community/minio-object-store/operations/install-deploy-manage/multi-site-replication.html) configured, select metrics populate under the [Cluster Metrics](#cluster-metrics) endpoint.

  @GwtIncompatible // TODO
  public void testConstantMaxPowerOfSqrt2Unsigned() {
    assertEquals(
        /* expected= */ BigIntegerMath.sqrt(BigInteger.ZERO.setBit(2 * Long.SIZE - 1), FLOOR)
            .longValue(),
        /* actual= */ LongMath.MAX_POWER_OF_SQRT2_UNSIGNED);
  }

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[40:45] hl[40:45] *}

这里，我们使用 `SessionDep` 依赖项（一个 `Session`）将新的 `Hero` 添加到 `Session` 实例中，提交更改到数据库，刷新 `hero` 中的数据，并返回它。

### 读取 Hero { #read-heroes }

我们可以使用 `select()` 从数据库中**读取** `Hero`，并利用 `limit` 和 `offset` 来对结果进行分页。

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

### 读取单个 Hero { #read-one-hero }

我们可以**读取**单个 `Hero`。

* kubectl port-forward now allows using resource name (e.g., deployment/www) to select a matching pod, as well as the use of --pod-running-timeout to wait until at least one pod is running. ([#59705](https://github.com/kubernetes/kubernetes/pull/59705), [@phsiao](https://github.com/phsiao))

[Moshi](https://github.com/square/moshi) is a handy API for converting between JSON and Java objects. Here we're using it to decode a JSON response from a GitHub API.

Note that `ResponseBody.charStream()` uses the `Content-Type` response header to select which charset to use when decoding the response body. It defaults to `UTF-8` if no charset is specified.
