动态数据透视中的行和列总数

Question

在SQL Server 2008中，我有一个包含3列的表（tblStock）：

  

  
• PartCode（NVARCHAR（50））
  
• StockQty（INT）
  
• 位置（NVARCHAR（50））
  

下面的一些示例数据：

    PartCode    StockQty    Location
   .........   .........    .........
    A              10        WHs-A
    B              22        WHs-A
    A               1        WHs-B
    C              20        WHs-A
    D              39        WHs-F
    E               3        WHs-D
    F               7        WHs-A
    A               9        WHs-C
    D               2        WHs-A
    F              54        WHs-E

如何创建程序以获得如下结果？

PartCode    WHs-A   WHs-B   WHs-C   WHs-D   WHs-E   WHs-F   Total
........    .....   .....   .....  ......   .....   .....   .....
A            10       1       9       0       0       0      20
B            22       0       0       0       0       0      22
C            20       0       0       0       0       0      20
D             2       0       0       0       0      39      41
E             0       0       0       3       0       0       3
F             7       0       0       0      54       0      61
Total        61       1       9       3      54      39     167

非常感谢您的帮助，谢谢。

样本表

SELECT * INTO #tblStock
FROM
(
SELECT 'A' PartCode,  10 StockQty, 'WHs-A' Location
UNION ALL
SELECT 'B',   22,  'WHs-A'
UNION ALL
SELECT 'A',   1,   'WHs-B'
UNION ALL
SELECT 'C',   20,  'WHs-A'
UNION ALL
SELECT 'D',   39,  'WHs-F'
UNION ALL
SELECT 'E',   3,   'WHs-D'
UNION ALL
SELECT 'F',   7,   'WHs-A'
UNION ALL
SELECT 'A',   9,   'WHs-C'
UNION ALL
SELECT 'D',   2,   'WHs-A'
UNION ALL
SELECT 'F',   54,  'WHs-E'
)TAB

获取动态旋转的列，并​​将NULL替换为zero

DECLARE @cols NVARCHAR (MAX)

SELECT @cols = COALESCE (@cols + ',[' + Location + ']', '[' + Location + ']')
               FROM (SELECT DISTINCT Location FROM #tblStock) PV 
               ORDER BY Location 
-- Since we need Total in last column, we append it at last
SELECT @cols += ',[Total]'


--Varible to replace NULL with zero
DECLARE @NulltoZeroCols NVARCHAR (MAX)

SELECT @NullToZeroCols = SUBSTRING((SELECT ',ISNULL(['+Location+'],0) AS ['+Location+']' 
FROM (SELECT DISTINCT Location FROM #tblStock)TAB  
ORDER BY Location FOR XML PATH('')),2,8000) 

SELECT @NullToZeroCols += ',ISNULL([Total],0) AS [Total]'

您可以使用CUBE查找行总列数，并将NULL替换为Total，以便从CUBE生成行。

DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT PartCode,' + @NulltoZeroCols + ' FROM 
             (
                 SELECT 
                 ISNULL(CAST(PartCode AS VARCHAR(30)),''Total'')PartCode, 
                 SUM(StockQty)StockQty , 
                 ISNULL(Location,''Total'')Location              
                 FROM #tblStock
                 GROUP BY Location,PartCode
                 WITH CUBE
             ) x
             PIVOT 
             (
                 MIN(StockQty)
                 FOR Location IN (' + @cols + ')
            ) p
            ORDER BY CASE WHEN (PartCode=''Total'') THEN 1 ELSE 0 END,PartCode' 

EXEC SP_EXECUTESQL @query

<强> RESULT

注意：如果您希望NULL代替zero作为值，请在动态透视代码中使用@cols代替@NulltoZeroCols

编辑：

<强> 1。仅显示行总计

• 请勿使用代码SELECT @cols += ',[Total]'和SELECT @NullToZeroCols += ',ISNULL([Total],0) AS [Total]'。
• 使用ROLLUP代替CUBE。

<强> 2。仅显示列总计

• 使用代码SELECT @cols += ',[Total]'和SELECT @NullToZeroCols += ',ISNULL([Total],0) AS [Total]'。
• 使用ROLLUP代替CUBE。
• 将GROUP BY Location,PartCode更改为GROUP BY PartCode,Location。
• 使用ORDER BY CASE WHEN (PartCode=''Total'') THEN 1 ELSE 0 END,PartCode。
而不是WHERE PartCode<>''TOTAL'' ORDER BY PartCode

更新：将PartName用于OP

我正在更新以下查询以添加PartName结果。由于PartName会在CUBE添加额外结果，并且为了避免在AND或OR条件中出现混淆，因此最好将轮播结果与DISTINCT值相关联你的源表。

DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT P.PartCode,T.PartName,' + @NulltoZeroCols + ' FROM 
             (                
                 SELECT 
                 ISNULL(CAST(PartCode AS VARCHAR(30)),''Total'')PartCode, 
                 SUM(StockQty)StockQty , 
                 ISNULL(Location,''Total'')Location              
                 FROM #tblStock
                 GROUP BY Location,PartCode
                 WITH CUBE                   
             ) x
             PIVOT 
             (
                 MIN(StockQty)
                 FOR Location IN (' + @cols + ')
            ) p
            LEFT JOIN
            (  
                SELECT DISTINCT PartCode,PartName
                FROM #tblStock  
            )T
            ON P.PartCode=T.PartCode
            ORDER BY CASE WHEN (P.PartCode=''Total'') THEN 1 ELSE 0 END,P.PartCode'

您需要使用case based aggregation来转动数据

要使total行使用union

如果事先不知道Location值，则需要构建dynamic query

您也可以使用pivot关键字来执行相同操作。

select partCode,
 sum( case when Location='WHs-A' then StockQty
      else 0 end
    ) as 'Whs-A',
 sum( case when Location='WHs-B' then StockQty
      else 0 end
    ) as 'Whs-B',
sum(StockQty) as 'Total'
from tblStock
group by partCode
union all
select 'Total' as 'partCode',
sum( case when Location='WHs-A' then StockQty
    else 0 end ) as 'Whs-A',
sum( case when Location='WHs-B' then StockQty
    else 0 end) as 'Whs-B',
sum(StockQty) as 'Total'
from tblStock
