PIVOT의 SQL - 안내

Question

나는 다음과 같은 코드가 있습니다

SELECT * 
    FROM 
     ( 
     SELECT p.ProductID, pc.Name, ISNULL(p.Color, 'Uncolored') AS Color 
     FROM SalesLT.ProductCategory AS pc 
     INNER JOIN SalesLT.Product AS p ON pc.ProductCategoryID = p.ProductCategoryID 
     ) 
    AS PPC 
    PIVOT (COUNT(ProductID) FOR COLOR IN ([Red], [Blue], [Black], [Silver], [Yellow], [Grey], [Multi], [Uncolored])) 
    AS ColorPivotTable 

이것은 follwing을 출력을 제공을 :

Answer 1

당신은 여기에 비슷한 질문 찾을 수 : CUBE를 사용

Using pivot table with column and row totals in sql server 2008

이 솔루션은 CTE를 사용

WITH SalesLT_ProductCategory as (
    SELECT * FROM (
     VALUES 
      (1, 'Mountain Bikes'), 
      (2, 'Road Bikes'), 
      (3, 'Touring Bikes'), 
      (4, 'Brakes') 
      -- etc... 
     ) AS a (ProductCategoryID, Name) 
), SalesLT_Product AS (
    SELECT * FROM (
     VALUES 
      (1, 1, 'Red'), 
      (1, 1, 'Blue'), 
      (1, 1, 'Blue'), 
      (1, 1, 'Blue'), 

      (1, 2, 'Red'), 
      (1, 2, 'Red'), 
      (1, 2, 'Blue'), 
      (1, 2, 'Black'), 

      (1, 3, 'Black'), 
      (1, 3, 'Yellow'), 
      (1, 3, 'Grey'), 
      (1, 3, 'Grey'), 
      (1, 3, 'Grey'), 

      (1, 4, 'Red'), 
      (1, 4, 'Multi'), 
      (1, 4, 'Multi'), 
      (1, 4, 'Uncolored'), 
      (1, 4, 'Uncolored'), 
      (1, 4, 'Uncolored') 
      -- etc... 
     ) AS a (ProductID, ProductCategoryID, Color) 
), BaseData AS (
     SELECT p.ProductID, pc.Name, ISNULL(p.Color, 'Uncolored') AS Color 
     FROM SalesLT_ProductCategory AS pc 
     INNER JOIN SalesLT_Product AS p ON pc.ProductCategoryID = p.ProductCategoryID 
) 
SELECT 
    Name, 
    COALESCE(Red, 0) AS Red, 
    COALESCE(Blue, 0) AS Blue, 
    COALESCE(Black, 0) AS Black, 
    COALESCE(Silver, 0) AS Silver, 
    COALESCE(Yellow, 0) AS Yellow, 
    COALESCE(Grey, 0) AS Grey, 
    COALESCE(Multi, 0) AS Multi, 
    COALESCE(Uncoloured, 0) AS Uncoloured, 
    Total 
FROM (
    SELECT 
    COALESCE(Name, 'Total') AS Name, 
    COALESCE(Color, 'Total') AS Color, 
    COUNT(*) AS Count 
    FROM BaseData 
    GROUP BY CUBE (Name, Color) 
) AS t 
PIVOT (
    SUM(Count) FOR Color IN (
    Red, Blue, Black, Silver, Yellow, 
    Grey, Multi, Uncoloured, Total 
) 
) AS p 
ORDER BY CASE Name WHEN 'Total' THEN 1 ELSE 0 END, Name 

이 될 수를, 대체 솔루션이 될 수

WITH SalesLT_ProductCategory as (
    SELECT * FROM (
     VALUES 
      (1, 'Mountain Bikes'), 
      (2, 'Road Bikes'), 
      (3, 'Touring Bikes'), 
      (4, 'Brakes') 
      -- etc... 
     ) AS a (ProductCategoryID, Name) 
), SalesLT_Product as (
    SELECT * FROM (
     VALUES 
      (1, 1, 'Red'), 
      (1, 1, 'Blue'), 
      (1, 1, 'Blue'), 
      (1, 1, 'Blue'), 

      (1, 2, 'Red'), 
      (1, 2, 'Red'), 
      (1, 2, 'Blue'), 
      (1, 2, 'Black'), 

      (1, 3, 'Black'), 
      (1, 3, 'Yellow'), 
      (1, 3, 'Grey'), 
      (1, 3, 'Grey'), 
      (1, 3, 'Grey'), 

      (1, 4, 'Red'), 
      (1, 4, 'Multi'), 
      (1, 4, 'Multi'), 
      (1, 4, 'Uncolored'), 
      (1, 4, 'Uncolored'), 
      (1, 4, 'Uncolored') 
      -- etc... 
     ) AS a (ProductID, ProductCategoryID, Color) 
), PivotData AS (
    -- your query 
    SELECT * 
    FROM 
     ( 
     SELECT p.ProductID, pc.Name, ISNULL(p.Color, 'Uncolored') AS Color 
     FROM SalesLT_ProductCategory AS pc 
     INNER JOIN SalesLT_Product AS p ON pc.ProductCategoryID = p.ProductCategoryID 
     ) 
    AS PPC 
    PIVOT (COUNT(ProductID) FOR COLOR IN ([Red], [Blue], [Black], [Silver], [Yellow], [Grey], [Multi], [Uncolored])) 
    AS ColorPivotTable 
), ColumnTotals AS (
    -- column totals 
    SELECT 
      'Total' AS Name 
     , SUM(Red) AS Red 
     , SUM(Blue) AS Blue 
     , SUM(Black) AS Black 
     , SUM(Silver) AS Silver 
     , SUM(Yellow) AS Yellow 
     , SUM(Grey) AS Grey 
     , SUM(Multi) AS Multi 
     , SUM(Uncolored)AS Uncolored 
    FROM PivotData 
), PivotDataWithRowTotals AS (
SELECT * FROM PivotData 
UNION ALL 
SELECT * FROM ColumnTotals 
) 
SELECT P.* 
    -- row totals 
    , P.Red + P.Blue + P.Black + P.Silver + P.Yellow + P.Grey + P.Multi + P.Uncolored as Total 
FROM PivotDataWithRowTotals AS P 

Answer 2

이것은 CUBE() (or GROUPING SETS) calculation의 좋은 예이며, d와 PIVOT representation, I had to write a blog post about it.

여기 당신이 찾고있는 정확하게 생산하고 그 해결책 :

WITH Bikes(Name, Colour) AS (
    SELECT * FROM (
    VALUES ('Mountain Bikes', 'Black'), 
      ('Mountain Bikes', 'Black'), 
      ('Mountain Bikes', 'Silver'), 
      ('Road Bikes', 'Red'), 
      ('Road Bikes', 'Red'), 
      ('Road Bikes', 'Red'), 
      ('Road Bikes', 'Black'), 
      ('Road Bikes', 'Yellow') 
) AS Bikes(Name, Colour) 
) 
SELECT 
    Name, 
    COALESCE(Red, 0) AS Red, 
    COALESCE(Blue, 0) AS Blue, 
    COALESCE(Black, 0) AS Black, 
    COALESCE(Silver, 0) AS Silver, 
    COALESCE(Yellow, 0) AS Yellow, 
    COALESCE(Grey, 0) AS Grey, 
    COALESCE(Multi, 0) AS Multi, 
    COALESCE(Uncoloured, 0) AS Uncoloured, 
    Total 
FROM (
    SELECT 
    Coalesce(Name, 'Total') Name, 
    COALESCE(Colour, 'Total') Colour, 
    COUNT(*) Count 
    FROM Bikes 
    GROUP BY CUBE (Name, Colour) 
) AS t 
PIVOT (
    MAX(Count) FOR Colour IN (
    Red, Blue, Black, Silver, Yellow, Grey, Multi, Uncoloured, Total 
) 
) AS p 
ORDER BY CASE Name WHEN 'Total' THEN 1 ELSE 0 END, Name
