到目前为止我尝试了什么：
declare @forFrom varchar(50) = '12/01/2017'
declare @forTo varchar(50) = '02/28/2018'
declare @cols nvarchar(max), @cols2 nvarchar(max), @query NVARCHAR(MAX)
select @cols = STUFF((SELECT DISTINCT ', MAX(' + QUOTENAME(supplyDesc) + ')' + '''' + supplyDesc + ''''
FROM (select a.id'supplyID',
a.supplyDesc,
SUBSTRING(d.fullName, 5, LEN(MAX(d.fullName)))fullName,
SUM(CASE WHEN ((CAST(c.forFrom as datetime) >= @forFrom and CAST(c.forTo as datetime) <= @forTo)) THEN b.qty ELSE 0 END)totalQty
from Supplies a
left join SupplyRequestDetails b
on a.id = b.supplyID
left join SupplyRequests c
on b.rqID = c.id
left join Users d
on c.userID = d.id
where a.isActive = 1
or b.isActive = 1
group by a.id,
a.supplyDesc,
fullName
) as x
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'');
select @cols2 = STUFF((SELECT DISTINCT ',' + QUOTENAME(supplyDesc)
FROM (select a.id'supplyID',
a.supplyDesc,
SUBSTRING(d.fullName, 5, LEN(MAX(d.fullName)))fullName,
SUM(CASE WHEN ((CAST(c.forFrom as datetime) >= @forFrom and CAST(c.forTo as datetime) <= @forTo)) THEN b.qty ELSE 0 END)totalQty
from Supplies a
left join SupplyRequestDetails b
on a.id = b.supplyID
left join SupplyRequests c
on b.rqID = c.id

,1,1,'')
SET @query = N'
declare @forFrom varchar(50) = ''12/01/2017''
declare @forTo varchar(50) = ''02/28/2018''
SELECT SUBSTRING(fullName, 5, LEN(fullName))fullName, ' + @cols + '
FROM (SELECT SUBSTRING(fullName, 5, LEN(fullName))fullName, ' + @cols + '
FROM (select a.id''supplyID'',

SUBSTRING(d.fullName, 5, LEN(MAX(d.fullName)))fullName,
SUM(CASE WHEN ((CAST(c.forFrom as datetime) >= @forFrom and CAST(c.forTo as datetime) <= @forTo)) THEN b.qty ELSE 0 END)totalQty

group by a.id,
a.supplyDesc,
fullName
) as j
PIVOT (
SUM(totalQty) FOR supplyDesc IN ('
+ @cols2
+ ')
) AS a
WHERE fullName is not null
GROUP BY fullName
ORDER BY fullName;';
PRINT @query
EXEC sp_executesql @query
结果有点像：
fullName Ballpen Adhesive Tape White Paper
Mr.Joe 6303 9505 NULL
预期结果集：
fullName uqStores Ballpen Adhesive Tape White Paper
Mr. Joe 3 6000 4000 NULL
Mr. Bean 2 300 500 NULL
正如您可能注意到的那样，我首先尝试从“耗材”表中获取项目列表，然后尝试（但未通过）将每个项目标记给在给定条件（日期范围和活动状态）内分别请求每个项目的用户。然后，创建动态列并准备供应的枢轴。此外，我还没有弄清楚如何从这些查询中计算所有唯一的storeID。
我在想第一个问题是我是如何尝试将用户标记为每个项目的。但是，不知道如何同时使用一堆物品。
非常感谢您的帮助。
编辑：
我不得不修复一些问题。我相信我复制了错误的物品。

当然有更好的方法来做到这一点。我真的很喜欢你的建议。

从@sarslan的答案中得出并编辑：
DECLARE @Query NVARCHAR(MAX) = '
SELECT * FROM (
SELECT
S.supplyDesc
, fullName
, COUNT(DISTINCT storeID) [uqStores]
, SUM(qty) SumQty
FROM
Supplies S
LEFT JOIN ( SELECT U.fullName, supplyID, storeID, qty, SRD.isActive FROM SupplyRequestDetails SRD
INNER JOIN SupplyRequests SR ON SRD.rqID = SR.id AND ( SR.forFrom >= @forFrom AND SR.forTo <= @forTo )
INNER JOIN Users U ON SR.userID = U.userID ) AS ST ON ST.supplyID = S.id
WHERE ST.isActive = 1
GROUP BY fullName, supplyDesc
HAVING COUNT(DISTINCT storeID) > 1
) SRC
PIVOT ( SUM (SumQty) FOR supplyDesc IN ( ' + @ColNames + ')) PVT '
比方说，例如，SupplyRequestDetails中id为1的项目将变为非活动状态。
结果是：
fullName Ballpen Adhesive Tape White Paper
Mr. Bean 5000 NULL NULL
Mr. Bean NULL 9000 NULL
Mr. Joe 300 500 NULL

您可以使用此脚本。
declare @forFrom datetime = '12/01/2017'
declare @forTo datetime = '02/28/2018'
DECLARE @ColNames NVARCHAR(MAX)= ''
SELECT @ColNames = @ColNames + ',' + QUOTENAME (supplyDesc) FROM Supplies WHERE isActive = 1
SET @ColNames = STUFF(@ColNames,1,1,'')
DECLARE @Query NVARCHAR(MAX) = '
SELECT * FROM (
SELECT
S.supplyDesc
, fullName
, COUNT(DISTINCT storeID) [uqStores]
, SUM(qty) SumQty
FROM
Supplies S
LEFT JOIN ( SELECT U.fullName, supplyID, storeID, qty, SRD.isActive FROM SupplyRequestDetails SRD
INNER JOIN SupplyRequests SR ON SRD.rqID = SR.id AND ( SR.forFrom >= @forFrom AND SR.forTo <= @forTo )
INNER JOIN Users U ON SR.userID = U.userID
WHERE SRD.isActive = 1 ) AS ST ON ST.supplyID = S.id
WHERE S.isActive = 1
GROUP BY fullName, supplyDesc
HAVING COUNT(DISTINCT storeID) > 1
) SRC
PIVOT ( SUM (SumQty) FOR supplyDesc IN ( ' + @ColNames + ')) PVT '
EXEC sp_executesql @Query, N'@forFrom DATETIME, @forTo DATETIME' , @forFrom = @forFrom, @forTo = @forTo
结果：
