### Criar as Tabelas { #create-the-tables }

Em seguida, adicionamos uma função que usa `SQLModel.metadata.create_all(engine)` para **criar as tabelas** para todos os *modelos de tabela*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

使用 `check_same_thread=False` 可以让 FastAPI 在不同线程中使用同一个 SQLite 数据库。这很有必要，因为**单个请求**可能会使用**多个线程**（例如在依赖项中）。

不用担心，我们会按照代码结构确保**每个请求使用一个单独的 SQLModel *会话***，这实际上就是 `check_same_thread` 想要实现的。

### 创建表

然后，我们来添加一个函数，使用 `SQLModel.metadata.create_all(engine)` 为所有*表模型***创建表**。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### 创建会话（Session）依赖项

**`Session`** 会存储**内存中的对象**并跟踪数据中所需更改的内容，然后它**使用 `engine`** 与数据库进行通信。

걱정하지 마세요. 코드가 구조화된 방식으로 인해, 이후에 **각 요청마다 단일 SQLModel *세션*을 사용**하도록 보장할 것입니다. 실제로 그것이 `check_same_thread`가 하려는 것입니다.

### 테이블 생성하기

그 다음 `SQLModel.metadata.create_all(engine)`을 사용하여 모든 *테이블 모델*의 **테이블을 생성**하는 함수를 추가합니다.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### 세션 의존성 생성하기

			t.Errorf("Test %d: %s: Expected the response status to be `%d`, but instead found `%d`", i+1, instanceType, testCase.expectedRespStatus, rec.Code)
		}
		// When the operation is successful, check if sending metadata is successful too
		if rec.Code == http.StatusNoContent {
			objInfo, err := obj.GetObjectInfo(context.Background(), bucketName, testCase.objectName+"/upload.txt", opts)
			if err != nil {
