運行總計但不同

Question

我當前的查詢......

SELECT datepart(hour,s.prodtime) ProdHr 
    , Min(distinct R.FinalProd) Prod 
    , MIN(r.chargeseq) StartSeq 
    , MAX(r.chargeseq) EndSeq 
    , MIN(S.RollRecID) RID 
    , (MIN(r.locseq) + COUNT(DISTINCT S.RollRecID) - 1) endd 
    FROM NYS1Reheat R INNER JOIN NYS1SawPieces S ON R.locseq = S.RollRecID 
    where s.ShiftIdent = '06/03/15154B' and r.Location = 'HISTORY' 
    GROUP BY datepart(hour,s.prodtime) 
    order by RID 

它返回......

17 S18X70   14 17 542999660 542999663 
18 S18X70   18 41 542999700 542999720 
19 S18X54.7  40 61 542999920 542999940 
20 S18X54.7  62 79 543000140 543000157 
21 S18X54.7  80 105 543000320 543000345 
22 S18X54.7  106 133 543000580 543000606 
23 S18X54.7  134 171 543000860 543000897 
1 W16X100   1 5 543001250 543001254 
2 W16X100   6 17 543001300 543001311 
3 W16X100   18 32 543001420 543001434 
4 W16X77   33 42 543001570 543001578 
5 W16X77   41 51 543001650 543001659 

隨着最後兩列（9位數字），我需要減去從第一第二行，併爲每行創建另一個列/字段。 請幫忙嗎？

您可以做內聯：

SELECT datepart(hour,s.prodtime) ProdHr 
, Min(distinct R.FinalProd) Prod 
, MIN(r.chargeseq) StartSeq 
, MAX(r.chargeseq) EndSeq 
, MIN(S.RollRecID) RID 
, (MIN(r.locseq) + COUNT(DISTINCT S.RollRecID) - 1) endd 
, (MIN(r.locseq) + COUNT(DISTINCT S.RollRecID) - 1) - MIN(S.RollRecID) ColumnName 
FROM NYS1Reheat R INNER JOIN NYS1SawPieces S ON R.locseq = S.RollRecID 
where s.ShiftIdent = '06/03/15154B' and r.Location = 'HISTORY' 
GROUP BY datepart(hour,s.prodtime) 
order by RID 

還是把這一切都爲子查詢，並通過名字來稱呼它：

SELECT tbl.*, tbl.endd - tbl.RID as ColumnName 
FROM 
(
    SELECT datepart(hour,s.prodtime) ProdHr 
    , Min(distinct R.FinalProd) Prod 
    , MIN(r.chargeseq) StartSeq 
    , MAX(r.chargeseq) EndSeq 
    , MIN(S.RollRecID) RID 
    , (MIN(r.locseq) + COUNT(DISTINCT S.RollRecID) - 1) endd 
    FROM NYS1Reheat R INNER JOIN NYS1SawPieces S ON R.locseq = S.RollRecID 
    where s.ShiftIdent = '06/03/15154B' and r.Location = 'HISTORY' 
    GROUP BY datepart(hour,s.prodtime) 
    order by RID 
) as tbl
