但是在 ORM 模式下，由于 Pydantic 本身会尝试从属性访问它需要的数据（而不是假设为 `dict`），你可以声明你想要返回的特定数据，它甚至可以从 ORM 中获取它。

## CRUD工具

现在让我们看看文件`sql_app/crud.py`。

在这个文件中，我们将编写可重用的函数用来与数据库中的数据进行交互。

**CRUD**分别为：增加（**C**reate）、查询（**R**ead）、更改（**U**pdate）、删除（**D**elete），即增删改查。

...虽然在这个例子中我们只是新增和查询。

### 读取数据

从 `sqlalchemy.orm`中导入`Session`，这将允许您声明`db`参数的类型，并在您的函数中进行更好的类型检查和完成。

*   Added warmup capabilities to `tf.keras.optimizers.schedules.CosineDecay` learning rate scheduler. You can now specify an initial and target learning rate, and our scheduler will perform a linear interpolation between the two after which it will begin a decay phase.

   * The Least Recently Used page replacement algorithm was chosen due to its simplicity, high hit
   * rate, and ability to be implemented with O(1) time complexity. The initial LRU implementation
   * operates per-segment rather than globally for increased implementation simplicity. We expect
   * the cache hit rate to be similar to that of a global LRU algorithm.
