Є кілька відмінностей:

* `table=True` каже SQLModel, що це «таблична модель» - вона має представляти **таблицю** в SQL базі даних, а не просто «модель даних» (як будь-який інший звичайний клас Pydantic).

* `Field(primary_key=True)` каже SQLModel, що `id` - це **первинний ключ** у SQL базі даних (більше про первинні ключі в SQL див. у документації SQLModel).

 * to ensure thread isolation of bindings.</p>
 *
 * <p>Note on class-level isolation: Compiled Script classes are cached and reused.
 * Class-level state (static fields, metaclass mutations) persists across evaluations
 * of the same script. In Fess, scripts are short expressions configured by
 * administrators (e.g., "data1 &gt; 10", "10 * boost1 + boost2") and do not use

 * filter. The approach is to hook into JSSE log events for the messages between client and server
 * during handshake, and then take the agreed masterSecret from private fields of the session.
 *
 * Copy WireSharkKeyLoggerListener to your test code to use in development.
 *
 * This logs TLSv1.2 on a JVM (OpenJDK 11+) without any additional code.  For TLSv1.3
 * an existing external tool is required.

  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",

  ]
}
```

As `needy` is a required parameter, you would need to set it in the URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

這種情況下，你可以把標準的 `dataclasses` 直接換成 `pydantic.dataclasses`，它是可直接替換（drop-in replacement）的：

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. 我們仍然從標準的 `dataclasses` 匯入 `field`。
2. `pydantic.dataclasses` 是 `dataclasses` 的可直接替換版本。
3. `Author` dataclass 內含一個 `Item` dataclass 的清單。
4. `Author` dataclass 被用作 `response_model` 參數。
5. 你可以將其他標準型別註記與 dataclass 一起用作請求本文。

   在此例中，它是 `Item` dataclass 的清單。
