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 类

我们可以使用 `select()` 从数据库中**读取** `Hero` 类，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

我们可以**读取**单个 `Hero` 。
