    • SUM, COUNT, MIN, MAX, LAST 및 AVG를 포함한 집계 함수를 사용하여 테이블을 쿼리합니다.

    주:
    여기에 설명된 기능을 사용하려면 Aggregate Web Service 플러그인이 필요합니다.

    입력 필드

    대상 테이블의 모든 요소입니다. 또한 하나 이상의 집계 함수(SUM, COUNT, MIN, MAX, LAST 및 AVG)가 있습니다.

    GROUP BY 및 HAVING 절도 추가할 수 있습니다.

    출력 필드

    검색된 기록에 대한 모든 필드 값을 캡슐화하는 aggregateResponse 요소입니다.

    결과 범위를 좁히기 위해 HAVING을 사용하는 샘플 집계 요청입니다.

    HAVING은 4개의 필드를 사용합니다. 각 필드는 집계 유형, 집계 필드, 운영 유형 및 비교할 값인 "^"로 구분됩니다.

    요청에 두 개 이상의 HAVING을 추가할 수 있으므로 HAVING 식을 사용할 수 있지만 OR에 대한 지원은 없습니다.
