sql-server - 使用数据透视表排序

Question

SELECT * 
FROM 
   (SELECT 
       datename(month, [date]) as [Month],
       planttype, 
       (sum(noof50kgsbags * 50))[Total Kgs]  
    FROM
       K_FP_Indent 
    WHERE 
       (date BETWEEN '2013-04-01 00:00.000' AND getdate()) 
       AND (attrited = 'True') 
    GROUP BY 
       datename(month, [date]), month([date]), planttype,[date]) as s
PIVOT
(
    SUM([Total Kgs])
    FOR [planttype] IN (A,B,C,D)
) AS s2

如何对这个查询使用 order by 语句？我知道我们不能使用 order by 进行内联查询

输出：

Month   A       B         C      D
April   x       X         X      X
August  X       X         X      X
July    X       X         X      X

所需的OP

Month   A       B         C      D
April   x       X         X      X
July    X       X         X      X
August  X       X         X      X

Answer 1

试试这个——

询问：

DECLARE @temp TABLE
(
      planttype CHAR(1)
    , [Date] DATETIME
    , noof50kgsbags FLOAT
    , attrited VARCHAR(5)
)

INSERT INTO @temp (planttype, [Date], noof50kgsbags, attrited)
VALUES 
    ('a', '20130401', 5, 'True'),
    ('b', '20130801', 5, 'True'),
    ('c', '20130701', 7, 'True')

SELECT s2.[Month], a, b, c, d
FROM
(
    SELECT
          [Month] = DATENAME(MONTH, [Date]) 
        , mt = MONTH([Date])
        , planttype
        , [Total Kgs] = SUM(noof50kgsbags * 50) 
    FROM @temp
    WHERE [Date] BETWEEN '2013-04-01 00:00.000' AND GETDATE()
        AND attrited = 'True'
    GROUP BY
          DATENAME(MONTH, [Date])
        , MONTH([Date])
        , planttype
) s
PIVOT
(
    SUM([Total Kgs])
    FOR [planttype] IN (a, b, c, D)
) s2
ORDER BY mt

输出：

Month     a      b       c       d
--------- ------ ------- ------- -------
April     250    NULL    NULL    NULL
July      NULL   NULL    350     NULL
August    NULL   250     NULL    NULL

更新： 如何使用 order by 子句来内联查询

SELECT *
FROM
(
    SELECT TOP (100) PERCENT --<--
          [Month] = DATENAME(MONTH, [Date]) 
        , planttype
        , [Total Kgs] = SUM(noof50kgsbags * 50) 
    FROM @temp
    WHERE [Date] BETWEEN '2013-04-01 00:00.000' AND GETDATE()
        AND attrited = 'True'
    GROUP BY
          DATENAME(MONTH, [Date])
        , MONTH([Date])
        , planttype
    ORDER BY MONTH([Date])
) s
PIVOT
(
    SUM([Total Kgs])
    FOR [planttype] IN (a, b, c, D)
) s2
