Question

我目前的查询...

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

使用最后两列（9位数字），我需要从第二列中减去第一列并创建另一列/每个行的差异。有什么帮助吗？

你可以内联：

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

或者将这些全部放入子查询中并按名称调用它：

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

运行总计但不同
