Create utility functions to:

* Read a single user by ID and by email.
* Read multiple users.
* Read multiple items.

```Python hl_lines="1  3  6-7  10-11  14-15  27-28"
{!../../../docs_src/sql_databases/sql_app/crud.py!}
```

!!! tip

导入之前的`models`（SQLAlchemy 模型）和`schemas`（Pydantic*模型*/模式）。

创建一些实用函数来完成：

* 通过 ID 和电子邮件查询单个用户。
* 查询多个用户。
* 查询多个项目。

```Python hl_lines="1  3  6-7  10-11  14-15  27-28"
{!../../../docs_src/sql_databases/sql_app/crud.py!}
```

!!! tip
    通过创建仅专用于与数据库交互（获取用户或项目）的函数，独立于*路径操作函数*，您可以更轻松地在多个部分中重用它们，并为它们添加单元测试。

### 创建数据

现在创建实用程序函数来创建数据。
