선입선출 조회 쿼리

fsffd 2020.10.26 11:23 Views : 641

아래와 같은 표의 데이터가 있습니다.

조회 기준은 조회년월로서 기초 + 입고 - 출고 = 기말재고의 형식인데,

이 데이터로 재고 연령조회를 해야합니다.

예를들어, 2020년 10월 기준 조회했을 때 품목명 / 1년미만 / 1년~2년 / 2년~3년 / 3년이상 의 네가지로 분류하여 조회해야되는데,

선입선출로 조회하여 각 년도별 몇개의 재고가 남았는지 확인하고싶습니다.

아래의 표를 예시로 2020년 10월로 조회했을 때

품목명 / 1년 미만 / 1년 ~ 2년 / 2년 ~ 3년 / 3년 이상

A 500 0 0 408 (총 재고의 합은 2020년 10월 기말재고)

고수님들의 조언을 듣고싶습니다.

10월말 재고가 908개 인데
1년미만 - 500개 / 1년~2년 - 0 / 2년~3년 - 0 / 3년이상 - 408개가 되는지를 이야기 하시는게 쉬울듯 합니다.

남아 있는 재고가 언제 들어온걸 이야기 하는 거라면 뭔가 이상 하구요 ..
선입선출이라는게 반대로 말하면 최근에 들어온게 남아 있다는 것과 일맥 상통하는거라.

네가지로 분류의 의미가 무엇인지 ?
자료를 보면 입고 출고 수량이 같은 경우가 있는데 기존재고를 나두고 입고해서 출고 시켰다는건지 ?

결과의 형태가 선입선출인데 3년이 남아 있고, 1년미만이 있다는 게 @.@
(그럴리 없을꺼 같다는 생각이라는...)
