Question

두 개의 쿼리가 있습니다. 첫 번째의 결과는 창고 부분의 - 남은 수량 :

PartNum OnHandQty IUM 
100009 19430.00 KG 

번째 조회 결과 창고에 물품의 영수증에 관한 트랜잭션 같습니다

TranDate  PartNum TranQty  UM Dayss 
2014-09-01 100009  10720.000 KG 2 
2014-09-01 100009  1340.000 KG 2 
2014-08-11 100009  8710.000 KG 23 
2014-08-11 100009  3350.000 KG 23 
2014-06-30 100009  9380.000 KG 65 

은 이 제로, 예를 돌 때까지 TranQty-

은 지금은 OnHandQy을 계산해야 나는 다음과 같은 표를받을 필요 결과

19430 - 10720 = 8710 --not enough 
8710 - 1340 = 7370 --not enough 
7370 - 8710 = -1340 --enough 

:

PartNum OnHandQty IUM [0-10 Days] [11-20 Days] [over 21 Days] 
100009 19430.00 KG 12060  null   8710 

모든 아이디어를 어떻게이 결과를 얻는 방법?

Answer 1

하나의 아이디어는 다음 쿼리를 사용하는 것입니다.

WITH(TranDate,PartNum,TranQty,UM,Dayss) trans 
AS 
(
    -- Your second query 
) 
SELECT F.PartNum 
    ,F.OnHandQty 
    ,F.IUM 
    ,SUM(t0to10.TransQty) AS [0-10 Days] 
    ,SUM(t11to20.TransQty) AS [11-20 Days] 
    ,SUM(tover20.TransQty) AS [over 21 Days] 
FROM (Your first query) AS F 
    JOIN trans AS t0to10 ON F.PartNum = t0to10.PartNum 
     AND t0to10.Dayss BETWEEN 0 AND 10 
    JOIN trans AS t11to20 ON F.PartNum = t11to20.PartNum 
     AND t11to20.Dayss BETWEEN 11 AND 20 
    JOIN trans AS tover20 ON F.PartNum = tover20.PartNum 
     AND tover20.Dayss >20 
GROUP BY F.PartNum,F.OnHandQty,F.IUM 

Answer 2

OnHandQty를 선언하고 while 루프에서 커서를 사용하면 이것을 정렬하는 데 도움이됩니다.
