Question

我正在使用SQL Server 2014.我有一个这样的表：

  MONTH      BILL AMOUNT       PAID AMOUNT
  Jan        2937.00           2940.00
  Dec        2938.00           2940.00
  Nov           0.00              0.00
  Oct        2940.00           2940.00
  Sep        2935.00           2940.00
  Aug        2936.00           2940.00

我想要这样的输出：

前6个月的比尔详情

  Month            Jan        Dec    Nov     Oct     Sep       Aug
    Bill Amount   2937.00    2938.00  0    2940.00 2935.00    2936.00
    Paid Amount   2940.00    2940.00  0    2940.00 2940.00    2940.00

有人可以建议解决方案吗？

Answer 1

我尝试过使用SQL Server 2008。指定的月份静态列名称。

select name as [MONTH], [Jan], [Dec], [Nov], [Oct], [Sep], [Aug]
from
(
 select [MONTH], name, value
 from testtable
 unpivot
 (
  value for name in (BILLAMOUNT, PAIDAMOUNT)
 ) unpiv
) src
 pivot
 (
 sum(value)
 for [MONTH] in ([Jan], [Dec], [Nov], [Oct], [Sep], [Aug])
) piv

当需要动态列月份时： -

DECLARE @colsUnpivot AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),
    @colsPivot as  NVARCHAR(MAX)

select @colsUnpivot = stuff((select ','+quotename(C.name)
         from sys.columns as C
         where C.object_id = object_id('test2') and
               C.name <> 'MONTH'
         for xml path('')), 1, 1, '')

select @colsPivot = STUFF((SELECT  ',' 
                      + quotename([MONTH])
                    from testtable t
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query 
  = 'select name as [MONTH], '+@colsPivot+'
      from
      (
        select [MONTH], name, value
        from testtable
        unpivot
        (
         value for name in ('+@colsUnpivot+')
        ) unpiv
      ) src
      pivot
      (
        sum(value)
        for [MONTH] in ('+@colsPivot+')
      ) piv'

exec(@query)

你可以试试这个，

    Create table #billing
    (
    [MONTH] varchar(15),
    [BILL_AMOUNT] Decimal(8,2),
    [PAID_AMOUNT] Decimal(8,2)
    )

    Insert Into #billing
    Values('Jan', 2937.00, 2940.00),
          ('Dec', 2938.00, 2940.00),
          ('Nov',  0.00  , 0.00 ),
          ('Oct', 2940.00, 2940.00),
          ('Sep', 2935.00, 2940.00),
          ('Aug', 2936.00, 2940.00)

    SELECT MONTH,BILL_AMOUNT,PAID_AMOUNT FROM #billing

    SELECT 'Bill Amount'as Month,Jan,Dec,Nov,Oct,Sep,Aug
    FROM (
        SELECT BILL_AMOUNT,MONTH
        FROM #billing
    ) AS source_table
    PIVOT
    (
        SUM(BILL_AMOUNT)
        FOR MONTH
        in(Jan,Dec,Nov,Oct,Sep,Aug) 
    )AS Pivot_table

    Union all

    SELECT 'Paid Amount'as Month,Jan,Dec,Nov,Oct,Sep,Aug
    FROM (
            SELECT PAID_AMOUNT,MONTH
            FROM #billing
    ) AS source_table
    PIVOT
    (
        SUM(PAID_AMOUNT)
        FOR MONTH
        in(Jan,Dec,Nov,Oct,Sep,Aug) 
    )AS Pivot_table

在sql中需要数据透视查询的帮助
