# SelectFields 클래스
<a name="aws-glue-api-crawler-pyspark-transforms-SelectFields"></a>

`SelectFields` 클래스는 기존 `DynamicFrame`에서 새 `DynamicFrame` 항목을 만들고 지정한 필드만 유지합니다. `SelectFields`는 SQL `SELECT` 문과 유사한 기능을 제공합니다.

## 예제
<a name="pyspark-SelectFields-examples"></a>

`DynamicFrame`에서 필드를 선택하기 위해 [`DynamicFrame.select_fields()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-select_fields) 방법을 사용하는 것이 좋습니다. 코드에 대한 예제는 [예: select\_fields를 사용하여 선택한 필드로 새 `DynamicFrame` 생성](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-select_fields-example) 단원을 참조하세요.

`DynamicFrame`의 필드(노드)를 얻습니다.
+ `frame` – `DynamicFrame`에서 필드를 선택합니다(필수).
+ `paths` - 선택할 필드의 전체 경로 목록입니다(필수).
+ `transformation_ctx` - 고유 문자열을 통해 상태 정보를 확인합니다(선택 사항).
+ `info` - 변환에 따른 오류 관련 문자열입니다(선택 사항).
+ `stageThreshold` - 오류가 발생하기 전까지 변환에 따라 생길 수 있는 최대 오류 수입니다(선택 사항). 기본값은 0입니다.
+ `totalThreshold` - 오류가 진행되기 전까지 생길 수 있는 최대 전체 오류 수입니다(선택 사항). 기본값은 0입니다.

특정 필드만 포함한 새로운 `DynamicFrame`을 반환합니다.
