在Sql Server中如何为多列进行透视

Question

这是我的示例表,我想转动类别列并将销售,库存和目标作为行

我想要这种形式的样本输出,如下所示,其中类别代替行和列代替行

Answer 1

样本表:

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

Answer 2

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

Answer 3

您必须更改下一个Pivot语句的列名称。

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

您已经准备好出发了...

您可以使用pv3的汇总对所需列进行汇总和分组。

来自答案1和答案2

（这不是OP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
