In SQL Server 2008, I have a table (tblStock) with 3 columns:

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

some example data below:

    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

How to create procedure to get the result as below?

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

Your help is much appreciated, thanks.

样品表

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替换NULL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来查找行和列总计，并替换NULL为Total从 生成的行CUBE。 

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：如果您想要NULL代替zero值，请在动态数据透视代码中使用@cols代替@NulltoZeroCols

编辑 ：

1. 仅显示行总计

  • 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为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：PartName为 OP带来

我正在更新以下查询以添加PartName结果。由于PartName将添加额外的结果CUBE并避免混淆AND或OR条件，因此最好将透视结果与DISTINCT源表中的值连接起来。

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' 

EXEC SP_EXECUTESQL @query

您需要使用case based aggregation来透视数据

获取total行使用union

如果Location事先不知道这些值，则需要构造一个dynamic query

你也可以使用pivot关键字来做同样的事情。

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
