/*
 * [업무 개요]
 *   가맹점 포털/정산 조회 화면에서 "가맹점 + 영업일" 조합의 승인 완료건
 *   요약(건수/합계/평균)을 단일 호출로 제공한다. 평균은 실수 대신 정수
 *   나눗셈(원 단위 절사)으로 산출하여 회계 표기와 일치시킨다.
 *
 * [집계 대상]
 *   status = 'M'(처리완료) 인 승인 전표만 포함. 접수(R)/취소(U)/정산(S) 는
 *   승인원장 요약에서 제외한다.
 *
 * [평균 산식]
 *   AVG = SUM / CNT   (정수 나눗셈; CNT=0 이면 미등록으로 별도 처리)
 *
 * [처리 절차]
 *   1) MERCHID, BIZDATE 추출 및 검증.
 *   2) 3개 조건(merch_id, biz_date, status='M') 단일 집계 SELECT.
 *   3) 건수 0 이면 RESP_NOMERCH.
 *   4) 평균 산출 및 원화 표기 구성 후 응답.
 *
 * [응답 필드]
 *   RESPCODE  처리결과코드
 *   MERCHID   가맹점번호(에코)
 *   BIZDATE   영업일(에코)
 *   CNT       승인 완료 건수
 *   SUM       승인 합계금액
 *   AVG       건당 평균(정수)
 *   AVGWON    평균 원화표기
 *
 * [주의]
 *   조회 전용. 집계는 항상 1행이므로 singleton SELECT INTO 를 사용한다.
