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

### 테이블 생성하기 { #create-the-tables }

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

Podría haber casos en los que devuelvas algo que no es un campo válido de Pydantic y lo anotes en la función, solo para obtener el soporte proporcionado por las herramientas (el editor, mypy, etc).
