这是我目前的查询：
SELECT dbo.TOL.sName AS sMacName, dbo.JOB.sName AS sJobName,

CASE

END as TOS

RIGHT OUTER JOIN dbo.TOL ON dbo.SHT_SUM.lMacRef = dbo.TOL.lTolRef

ORDER BY sMacName
并且它当前返回：

总结一下：
这在某种程度上可以用SQL吗？
答案 0 :(得分：1)
这是一个使用子查询进行第一轮分组的工作小提琴：SQL Fiddle
SQL表格创建（仅供小提琴参考）：
create table SHT_SUM_SCR (
sMacName nvarchar(100),
sJobName nvarchar(100),
tShiftBegin datetime,
tShiftEnd datetime,
dShots int,
dQuant int,
dScrap int,
SetCavity int,
TOS int
)
insert into SHT_SUM_SCR(sMacName,sJobName,tShiftBegin,tShiftEnd,dShots,dQuant,dScrap,SetCavity,TOS)
values('FT2-E14','10401445710','2014-05-13 05:00:00.000','2014-05-13 13:00:00.000',98,450,2,2,0)
insert into SHT_SUM_SCR(sMacName,sJobName,tShiftBegin,tShiftEnd,dShots,dQuant,dScrap,SetCavity,TOS)

insert into SHT_SUM_SCR(sMacName,sJobName,tShiftBegin,tShiftEnd,dShots,dQuant,dScrap,SetCavity,TOS)

查询以获得结果：
select sMacName,
tShiftBegin,
tShiftEnd,
sum(dShots) as dshots,
dQuant,
sum(dScrap) as dScrap,
SetCavity,
sum(TOS) as TOS
from
(
-- subquery - place your query here
select sMacName,sJobName,tShiftBegin,tShiftEnd,
dShots,dQuant,dScrap,SetCavity,sum(TOS) as tos
from SHT_SUM_SCR
group by sMacName,sJobName,tShiftBegin,tShiftEnd,dShots,dQuant,dScrap,SetCavity
-- subquery end
) as results
group by sMacName,tShiftBegin,tShiftEnd,dQuant,SetCavity
如果修改此查询并围绕查询包装外部SQL，则应得到相同的结果。

这可能不是最有效的解决方案，但确实可以解决问题。
从您的原始查询开始（为了便于阅读而编辑了一点）：
SELECT
t.sName AS sMacName
, j.sName AS sJobName
, ss.tShtBegin AS tShiftBegin
, ss.tShtEnd AS tShiftEnd
, SUM(ss.dActShots) AS dShots
, '450' AS dQuant
, SUM(ss.dActScrap) AS dScrap
, MAX(j.iSetCavity) as SetCavity
, CASE
WHEN (scr.iScrap) LIKE '99' THEN (scr.dActScrap)
ELSE '0'
END as TOS
FROM dbo.SHT_SUM_SCR scr
RIGHT OUTER JOIN dbo.SHT_SUM ss ON scr.lShtSumRef = ss.lShtSumRef
LEFT OUTER JOIN dbo.JOB j ON ss.lJobRef = j.lJobRef
RIGHT OUTER JOIN dbo.TOL t ON ss.lMacRef = t.lTolRef
WHERE 1=1
and t.bInactive = 0
AND (ss.tShtDay > DATEADD(DAY, - 1, CONVERT(DATE, GETDATE())))
AND (GETDATE() BETWEEN ss.tShtBegin AND ss.tShtEnd)
AND (j.iSetCavity is Not NUll)
GROUP BY
t.sName
, ss.tShtBegin
, ss.tShtEnd
, j.sName
, scr.iScrap
, scr.dActScrap
--ORDER BY sMacName
返回

我将此查询放在子查询中，以便按sJobName分组：
select
i.sMacName
, i.sJobName
, i.tShiftBegin
, i.tShiftEnd
, max(i.dShots ) as dShots
, i.dQuant
, max(i.dScrap ) as dScrap
, i.SetCavity
, sum(i.TOS ) as TOS
from (
SELECT
t.sName AS sMacName
, j.sName AS sJobName
, ss.tShtBegin AS tShiftBegin
, ss.tShtEnd AS tShiftEnd
, SUM(ss.dActShots) AS dShots
, '450' AS dQuant
, SUM(ss.dActScrap) AS dScrap
, MAX(j.iSetCavity) as SetCavity
, CASE
WHEN (scr.iScrap) LIKE '99' THEN (scr.dActScrap)
ELSE '0'
END as TOS
FROM dbo.SHT_SUM_SCR scr
RIGHT OUTER JOIN dbo.SHT_SUM ss ON scr.lShtSumRef = ss.lShtSumRef
LEFT OUTER JOIN dbo.JOB j ON ss.lJobRef = j.lJobRef
RIGHT OUTER JOIN dbo.TOL t ON ss.lMacRef = t.lTolRef
WHERE 1=1
and t.bInactive = 0
AND (ss.tShtDay > DATEADD(DAY, - 1, CONVERT(DATE, GETDATE())))
AND (GETDATE() BETWEEN ss.tShtBegin AND ss.tShtEnd)
AND (j.iSetCavity is Not NUll)
GROUP BY
t.sName
, ss.tShtBegin
, ss.tShtEnd
, j.sName
, scr.iScrap
, scr.dActScrap
--ORDER BY sMacName
) i
group by
i.sMacName
, i.sJobName
, i.tShiftBegin
, i.tShiftEnd
--, i.dShots
, i.dQuant
--, i.dScrap
, i.SetCavity
--, i.TOS
返回：
sMacName sJobName tShiftBegin tShiftEnd dShots dQuant dScrap SetCavity TOS
FT2-E14 10401445710 2014-05-13 05:00:00.000 2014-05-13 13:00:00.000 98 450 2 2 0

然后可以再次将其放入子查询中，通过以下方式完成最后一组：
select
i2.sMacName
, 'IGNORE' as sJobName
, i2.tShiftBegin
, i2.tShiftEnd
, sum(i2.dShots)
, i2.dQuant
, sum(i2.dScrap)
, i2.SetCavity
, sum(i2.TOS)
from (
select
i.sMacName
, i.sJobName
, i.tShiftBegin
, i.tShiftEnd
, max(i.dShots ) as dShots
, i.dQuant
, max(i.dScrap ) as dScrap
, i.SetCavity
, sum(i.TOS ) as TOS
from (
SELECT
t.sName AS sMacName
, j.sName AS sJobName
, ss.tShtBegin AS tShiftBegin
, ss.tShtEnd AS tShiftEnd
, SUM(ss.dActShots) AS dShots
, '450' AS dQuant
, SUM(ss.dActScrap) AS dScrap
, MAX(j.iSetCavity) as SetCavity
, CASE
WHEN (scr.iScrap) LIKE '99' THEN (scr.dActScrap)
ELSE '0'
END as TOS
FROM dbo.SHT_SUM_SCR scr
RIGHT OUTER JOIN dbo.SHT_SUM ss ON scr.lShtSumRef = ss.lShtSumRef
LEFT OUTER JOIN dbo.JOB j ON ss.lJobRef = j.lJobRef
RIGHT OUTER JOIN dbo.TOL t ON ss.lMacRef = t.lTolRef
WHERE 1=1
and t.bInactive = 0
AND (ss.tShtDay > DATEADD(DAY, - 1, CONVERT(DATE, GETDATE())))
AND (GETDATE() BETWEEN ss.tShtBegin AND ss.tShtEnd)
AND (j.iSetCavity is Not NUll)
GROUP BY
t.sName
, ss.tShtBegin
, ss.tShtEnd
, j.sName
, scr.iScrap
, scr.dActScrap
--ORDER BY sMacName
) i
group by
i.sMacName
, i.sJobName
, i.tShiftBegin
, i.tShiftEnd
--, i.dShots
, i.dQuant
--, i.dScrap
, i.SetCavity
--, i.TOS
) i2
group by
i2.sMacName
, i2.tShiftBegin
, i2.tShiftEnd
, i2.dQuant
, i2.SetCavity
这肯定不是很好，但确实会回复：
sMacName sJobName tShiftBegin tShiftEnd (No column name) dQuant (No column name) SetCavity (No column name)
