在SQL Server中，如何为多个列进行数据透视（Pivot）

Question

这是我的示例表格，我想将类别列旋转并将销售额、库存和目标作为行

我想要的示例输出如下图所示，其中类别在列的位置，而行在列的位置

Answer 1

你需要为下一个数据透视表更改列名。

例如：

SELECT
*
FROM
(
  SELECT 
   Branch,
   Category,
   Category+'1' As Category1,
   Category+'2' As Category2,
   Sales, 
   Stock, 
   Target
  FROM TblPivot
 ) AS P

 -- For Sales
 PIVOT
 (
   SUM(Sales) FOR Category IN ([Panel], [AC], [Ref])
 ) AS pv1

 -- For Stock
 PIVOT
 (
   SUM(Stock) FOR Category1 IN ([Panel1], [AC1], [Ref1])
 ) AS pv2

 -- For Target
 PIVOT
 (
   SUM(Target) FOR Category2 IN ([Panel2], [AC2], [Ref2])
 ) AS pv3
 GO

---

现在，您已经准备就绪了....

您可以使用pv3的聚合功能对需要的列进行求和和分组。

这里的关键点是通过在末尾添加“1”或“2”来创建新的类别值。如果不这样做，透视查询将无法正常工作。 - Tim Biegeleisen

示例表格：

DECLARE @Table1 TABLE 
    (Branch varchar(9), Category varchar(9), Sales INT,Stock INT,Target INT)
;

INSERT INTO @Table1
    (Branch, Category, Sales, Stock,Target)
VALUES
    ( 'mumbai', 'panel', 10,4,15),
    ( 'mumbai', 'AC', 11,7,14),
    ( 'mumbai', 'Ref', 7,2,10),
    ( 'Delhi', 'panel',20,4,17),
    ( 'Delhi', 'AC', 5,2,12),
    ( 'Delhi', 'Ref', 10,12,22)
;

在 SQL Server 脚本中：

  Select BRANCH,COL,[panel],[AC],[Ref] from (
    select Branch,Category,COL,VAL from @Table1
    CROSS APPLY (VALUES ('Sales',Sales),
    ('Stock',Stock),
    ('Target',Target))CS (COL,VAL))T
    PIVOT (MAX(VAL) FOR Category IN ([panel],[AC],[Ref]))PVT
ORDER BY Branch DESC

只有当列（这里是销售、库存、目标）具有相同的数据类型时，才能正常运行。 - undefined

请尝试以下解决方案。

  -- Applying pivoting on multiple columns
SELECT
*
FROM
(
  SELECT 
   Category,
   Sales, 
  FROM TblPivot
 ) AS P

 -- For Sales
 PIVOT
 (
   SUM(Sales) FOR Category IN ([Panel], [AC], [Ref])
 ) AS pv1

union all

 -- For Stock
 SELECT
*
FROM
(
  SELECT 
   Category,
   Stock, 
  FROM TblPivot
 ) AS P

 PIVOT
 (
   SUM(Stock) FOR Category IN ([Panel], [AC], [Ref])
 ) AS pv2

union all

 -- For Target
 SELECT
*
FROM
(
  SELECT 
   Category,
   Target, 
  FROM TblPivot
 ) AS P

 PIVOT
 (
   SUM(Target) FOR Category IN ([Panel], [AC], [Ref])
 ) AS pv3
 GO

我收到了“无效的列名 'Category'”错误提示，请问你能给予建议吗？ - user482745

来自答案1 和 答案2

(这不是提问者的要求)

DECLARE @Table1 TABLE(Branch varchar(9), Category varchar(9), Sales INT,Stock INT,Target INT);

INSERT INTO @Table1
    (Branch, Category, Sales, Stock,Target)
VALUES
    ( 'mumbai', 'panel', 10,4,15),
    ( 'mumbai', 'AC', 11,7,14),
    ( 'mumbai', 'Ref', 7,2,10),
    ( 'Delhi', 'panel',20,4,17),
    ( 'Delhi', 'AC', 5,2,12),
    ( 'Delhi', 'Ref', 10,12,22);

SELECT
    Branch,
    SUM(Panel) As PanelSales,SUM([AC]) As ACSales,SUM([Ref]) As RefSales,
    SUM(Panel1) As PanelStock,SUM([AC1]) As ACStock,SUM([Ref1]) As RefStock,
    SUM(Panel2) As PanelTarget,SUM([AC2]) As ACTarget,SUM([Ref2]) As RefTarget
FROM
(
  SELECT 
   Branch,
   Category,
   Category+'1' As Category1,
   Category+'2' As Category2,
   Sales, 
   Stock, 
   Target
  FROM @Table1
 ) AS P

 -- For Sales
 PIVOT
 (
   SUM(Sales) FOR Category IN ([Panel], [AC], [Ref])
 ) AS pv1

 -- For Stock
 PIVOT
 (
   SUM(Stock) FOR Category1 IN ([Panel1], [AC1], [Ref1])
 ) AS pv2

 -- For Target
 PIVOT
 (
   SUM(Target) FOR Category2 IN ([Panel2], [AC2], [Ref2])
 ) AS pv3
 Group BY Branch
 GO

Answer 5

以下代码应该可以正常工作：

select * FROM
(
  SELECT 
   Branch,
   Category,
   Sales, 
   Stock, 
   Target
  FROM Table1
 ) AS P
 unpivot
 (
 [Value] FOR [OutPut] IN (sales,stock,[target])
 )unpvt
 pivot
 (
 max([Value]) for  Category in (Panel,AC,Ref) 
 )pvt
order by Branch Desc

Answer 6

你可以先使用 UNPIVOT 将数据转换为平面表，然后再使用 PIVOT 将类别转换为列：

SELECT *
FROM SampleTable
UNPIVOT (Amount FOR Output IN (Sales, Stock, Target)) upvt
PIVOT (SUM(Amount) FOR Category IN (Panel, AC, Ref)) pvt
ORDER BY Branch, Output;
