【中文标题】您可以对数据透视表中的行和/或列进行小计吗？【英文标题】：Can you subtotal rows and/or columns in a pivot table? 【发布时间】：2011-12-17 01:35:23 【问题描述】：我有一组输出数据透视表的查询。是否可以获取数据透视表的行和/或列小计？
我从中选择的表看起来像这样
Site FormID Present
Site 1 Form A Yes
Site 1 Form B Yes
Site 1 Form D Yes
等等……
我的数据透视表查询是这样的
SELECT *
FROM (SELECT Site, COUNT(FormID) AS NumberOfForms,FormID
FROM @CRFCount WHERE Present='Yes'
GROUP BY Site, FormID) d
PIVOT
(SUM(NumberOfForms)
FOR [Site] IN ([Site 1], [Site 2], [Site 3])
) AS p;
但我真的希望它能够导致这个（当然这对我来说并不完全）
FormID Site 1 Site 2 Site 3 Total
Form A 8 8 15 31
Form B 14 4 NULL 18
Form C 14 NULL NULL 14
Form D 15 3 16 34
Form E 12 4 NULL 16
Form F 14 5 5 24
Form G 14 8 6 28
Form H 22 10 15 47
Form I 15 10 16 41
Form J 15 5 16 36
Total 143 57 89 289
感谢您的帮助！

【参考方案1】：;WITH C as
(
SELECT FormID,
[Site 1],
[Site 2],
[Site 3],
(SELECT SUM(S)
FROM (VALUES([Site 1]),
([Site 2]),
([Site 3])) AS T(S)) as Total
FROM (SELECT Site, COUNT(FormID) AS NumberOfForms,FormID
FROM @CRFCount WHERE Present='Yes'
GROUP BY Site, FormID) d
PIVOT
(SUM(NumberOfForms)
FOR [Site] IN ([Site 1], [Site 2], [Site 3])
) AS p
)
SELECT *
FROM
(
SELECT FormID,
[Site 1],
[Site 2],
[Site 3],
Total
FROM C
UNION ALL
SELECT 'Total',
SUM([Site 1]),
SUM([Site 2]),
SUM([Site 3]),
SUM(Total)
FROM C
) AS T
ORDER BY CASE WHEN FormID = 'Total' THEN 1 END
注意：如果您使用的是 SQL Server 2005，则需要更改：
(SELECT SUM(S)
FROM (VALUES([Site 1]),
([Site 2]),
([Site 3])) AS T(S)) as Total
到
(SELECT SUM(S)
FROM (SELECT [Site 1] UNION ALL
SELECT [Site 2] UNION ALL
SELECT [Site 3]) AS T(S)) as Total

【参考方案2】：试试这个（未测试）：
SELECT *
FROM
(
SELECT
Site = case when grouping(Site)=1 then 'All' else Site end,
FormID = case when grouping(FormID)=1 then 'All' else cast(FormID as varchar(100)) end,
measure = count(NumberOfForms)
FROM @CRFCount
-- chose below
GROUP BY Site, FormID with cube --(ms sql 2005)
--group by grouping sets(Site, FormID, (Site, FormID), ()) --(ms sql 2008)
) AS BOM
PIVOT (max(measure) FOR [Site] IN ([Site 1], [Site 2], [Site 3], [All]))
as pv
【讨论】：
在 SQL Server 2008 中，它可能只是GROUP BY CUBE (Site, FormID)，尽管您的 GROUPING SETS () 等效于 CUBE () 也是正确的。【参考方案3】：
示例表
SELECT * INTO #TEMP
FROM
(
SELECT 'Site 1' [Site], 'Form A' [FormID], 'Yes' Present
UNION ALL
SELECT 'Site 1', 'Form B', 'Yes'
UNION ALL
SELECT 'Site 1', 'Form C', 'Yes'
UNION ALL
SELECT 'Site 1', 'Form B', 'NO'
UNION ALL
SELECT 'Site 1', 'Form C', 'NO'
UNION ALL
SELECT 'Site 2', 'Form A', 'Yes'
UNION ALL
SELECT 'Site 2', 'Form A', 'Yes'
UNION ALL
SELECT 'Site 2', 'Form B', 'Yes'
UNION ALL
SELECT 'Site 2', 'Form B', 'NO'
UNION ALL
SELECT 'Site 2', 'Form C', 'Yes'
UNION ALL
SELECT 'Site 3', 'Form B', 'Yes'
UNION ALL
SELECT 'Site 3', 'Form A', 'Yes'
UNION ALL
SELECT 'Site 3', 'Form C', 'Yes'
UNION ALL
SELECT 'Site 3', 'Form A', 'Yes'
)TAB
1.行和列总计
-- Get the columns for dynamic pivot
DECLARE @cols NVARCHAR (MAX)
SELECT @cols = COALESCE (@cols + ',[' + [Site] + ']', '[' + [Site] + ']')
FROM (SELECT DISTINCT [Site] FROM #TEMP WHERE Present='YES') PV
ORDER BY [Site]
-- Since we need Total in last column, we append it at last
SELECT @cols += ',[Total]'
您可以使用CUBE 获取旋转时的行和列总数。更多关于CUBEhere。
DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT FORMID,' + @cols + ' FROM
(
SELECT
ISNULL([SITE],''Total'')[SITE],
SUM(CNT)CNT ,
ISNULL(FORMID,''Total'')FORMID
FROM
(
SELECT DISTINCT [SITE],FORMID,
COUNT(FORMID) OVER(PARTITION BY [SITE],FORMID) CNT
FROM #TEMP
WHERE PRESENT=''YES''
)TAB
GROUP BY [SITE],FORMID
WITH CUBE
) x
PIVOT
(
MIN(CNT)
FOR [SITE] IN (' + @cols + ')
) p
ORDER BY CASE WHEN (FORMID=''Total'') THEN 1 ELSE 0 END,FORMID'
EXEC SP_EXECUTESQL @query
2。仅行总计
您可以使用ROLLUP 获取行总数。
-- Get the columns for dynamic pivot
DECLARE @cols NVARCHAR (MAX)
SELECT @cols = COALESCE (@cols + ',[' + [Site] + ']', '[' + [Site] + ']')
FROM (SELECT DISTINCT [Site] FROM #TEMP WHERE Present='YES') PV
ORDER BY [Site]
DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT FORMID,' + @cols + ' FROM
(
SELECT
ISNULL([SITE],''Total'')[SITE],
SUM(CNT)CNT ,
ISNULL(FORMID,''Total'')FORMID
FROM
(
SELECT DISTINCT [SITE],FORMID,
COUNT(FORMID) OVER(PARTITION BY [SITE],FORMID) CNT
FROM #TEMP
WHERE PRESENT=''YES''
)TAB
GROUP BY [SITE],FORMID
WITH ROLLUP
) x
PIVOT
(
MIN(CNT)
FOR [SITE] IN (' + @cols + ')
) p
ORDER BY CASE WHEN (FORMID=''Total'') THEN 1 ELSE 0 END,FORMID'
EXEC SP_EXECUTESQL @query
3.仅列总计
将GROUP BY [SITE],FORMID 更改为GROUP BY FORMID,[SITE]
-- Get the columns for dynamic pivot
DECLARE @cols NVARCHAR (MAX)
SELECT @cols = COALESCE (@cols + ',[' + [Site] + ']', '[' + [Site] + ']')
FROM (SELECT DISTINCT [Site] FROM #TEMP WHERE Present='YES') PV
ORDER BY [Site]
--Since we need Total in last column, we append it at last
SELECT @cols += ',[Total]'
DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT FORMID,' + @cols + ' FROM
(
SELECT
ISNULL([SITE],''Total'')[SITE],
SUM(CNT)CNT ,
ISNULL(FORMID,''Total'')FORMID
FROM
(
SELECT DISTINCT [SITE],FORMID,
COUNT(FORMID) OVER(PARTITION BY [SITE],FORMID) CNT
FROM #TEMP
WHERE PRESENT=''YES''
)TAB
GROUP BY FORMID,[SITE]
WITH ROLLUP
) x
PIVOT
(
MIN(CNT)
FOR [SITE] IN (' + @cols + ')
) p
WHERE FORMID <> ''Total''
ORDER BY FORMID'
EXEC SP_EXECUTESQL @query
现在，如果你想用零替换 null，你可以在动态透视之前使用下面的代码。
DECLARE @NulltoZeroCols NVARCHAR (MAX)
SELECT @NullToZeroCols = SUBSTRING((SELECT ',ISNULL(['+[Site]+'],0) AS ['+[Site]+']'
FROM (SELECT DISTINCT [Site] FROM #TEMP)TAB
ORDER BY [Site] FOR XML PATH('')),2,8000)
SELECT @NullToZeroCols += ',ISNULL([Total],0) AS [Total]'
并且在动态枢轴的最外层查询中，将@cols 变量替换为@NullToZeroCols
