sql-server-2008 - 动态枢轴中的行和列总计

Question

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

• PartCode (NVARCHAR (50))
• StockQty (INT)
• Location (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。

sample 台

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

获取用于动态旋转的列并替换 NULL与 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查找行和列总数并替换 NULL与 Total对于从 CUBE 生成的行.

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

结果



注意:如果你想要 NULL而不是 zero作为值，使用 @cols而不是 @NulltoZeroCols在动态枢轴代码中

编辑:

1. 只显示行总数

不要使用代码SELECT @cols += ',[Total]'和 SELECT @NullToZeroCols += ',ISNULL([Total],0) AS [Total]' .

使用 ROLLUP而不是 CUBE .

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而不是 CUBE .

更改 GROUP BY Location,PartCode至 GROUP BY PartCode,Location .

而不是 ORDER BY CASE WHEN (PartCode=''Total'') THEN 1 ELSE 0 END,PartCode , 使用 WHERE PartCode<>''TOTAL'' ORDER BY PartCode .

更新:带来 PartName OP

我正在更新以下查询以添加 PartName结果。自 PartName将添加额外的结果 CUBE并避免混淆 AND或 OR条件下，最好将旋转结果与 DISTINCT 结合起来源表中的值。

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'
