Transpose table - Pivot SQL Server 2016

Question

我有一个 table 看起来像这样： SourceTable

CREATE TABLE [Temp].[tblMyleneTest]
(
    [DispOrder] [INT] NULL,
    [ReferencePeriod] [VARCHAR](7) NULL,
    [TypeOfGSUF] [VARCHAR](8) NULL,
    [FactAllocReferencePeriod] [VARCHAR](4) NULL,
    [Variable] [VARCHAR](50) NULL,
    [Value] [INT] NULL 
) ON [PRIMARY]


INSERT INTO [Temp].[tblMyleneTest]
VALUES (1, '201710F', 'Reduced', '2015', 'OperatingEntityNumberCount', '13540688'),
       (2, '201710F', 'Reduced', '2015', 'EnterpriseCodeCount', '6041138'),
       (3, '201710F', 'Reduced', '2015', 'EstablishmentCodeCount', '6554081'),
       (4, '201710F', 'Reduced', '2015', 'LocationCodeCount', '6600130'),
       (5, '201710F', 'Reduced', '2015', 'NAICSNotNullCount', '9943634'),
       (6, '201710F', 'Reduced', '2015', 'ReportingEntityNumbeCount', '2608'),
       (7, '201710F', 'Reduced', '2015', 'LocationCode_NotEverAliveCount', '2339'),
       (8, '201710F', 'Reduced', '2015', 'OperatingEntityNumberCountFF', '3078'),
       (1, '201706F', 'Reduced', '2014', 'OperatingEntityNumberCount', '13557946'),
       (2, '201706F', 'Reduced', '2014', 'EnterpriseCodeCount', '6046857'),
       (3, '201706F', 'Reduced', '2014', 'EstablishmentCodeCount', '6560136'),
       (4, '201706F', 'Reduced', '2014', 'LocationCodeCount', '6606226'),
       (8, '201706F', 'Reduced', '2014', 'OperatingEntityNumberCountFF', '3078')

我想将 ReferencePeriod、FactAllocReferencePeriod 和 TypeOfGSUF 分组。如您所见，同一个变量名有 2 条记录。在 ReferencePeriod 201710F 上，另一个在 201706F 上。我希望这些计数并排。我想要这样的东西：

Result Table

我能够旋转 table 来提升 ReferencePeriod。但不是相关的 FactAllocReferencePeriod/TypeOfGSUF...

SELECT * 
FROM [Temp].[tblMyleneTest]
PIVOT (MAX(value) FOR ReferencePeriod IN ([201710F], [201706F])) p

你能帮我解决这个问题吗？

Answer 1

引用 this answer on pivoting rows into columns

SELECT
    [Variable], piv.[201706F], piv.[201710F]
FROM 
(
    select [DispOrder], [Variable], [ReferencePeriod], [Value] from  #tblMyleneTest
) src
PIVOT (
    MAX([Value])
    FOR ReferencePeriod IN ([201710F],[201706F])
) piv

按 [DispOrder] 排序

Answer 2

我会为此使用条件聚合而不是数据透视表。语法对我来说不那么迟钝。

select variable
    , R201710f = max(case when ReferencePeriod = '201710F' then Value end)
    , F201706f = max(case when ReferencePeriod = '201706F' then Value end)
from tblMyleneTest
group by variable
order by variable

Answer 3

result

我丢失了 TypeOfGSUF 和 FactAllocReferencePeriod...

Answer 4

这是我的最后一段代码：

    -- Transpose tblSUFGenericCountsReportYYYYMM to get proper display --
SET @p_SQLCMD  = N' DROP TABLE IF EXISTS ' + @p_SUFReportTable + '' 
               + N' SELECT [DispOrder], [Variable], piv.[' + @p_ReferencePeriod2 + '], piv.[' + @p_ReferencePeriod1 + '] '
               + N' INTO ' + @p_SUFReportTable + ' from ( '
               + N' SELECT [DispOrder], [Variable], [ReferencePeriod], [Value] FROM  Temp.tblSUFGenericCountsReport ) src '
               + N' PIVOT ( MAX([Value]) FOR ReferencePeriod IN ([' + @p_ReferencePeriod1 + '],[' + @p_ReferencePeriod2 + ']) ) piv'
               + N' ORDER BY [DispOrder];'

EXEC sp_executesql @statement = @p_SQLCMD

然后添加缺失值：

-- Insert the TypeOfGSUF and FactorAllocationReferenceYear values to the report --
SET @p_SQLCMD  = N' INSERT INTO '+ @p_SUFReportTable +' (DispOrder, variable, "'+ @p_ReferencePeriod2 +'", "'+ @p_ReferencePeriod1 +'", Flag)'
               + N' VALUES (0 ,''TYPE OF GSUF'', "'+ @p_SUFMonthReduced +'", "'+ @p_SUFMonthReduced +'", Null),'
               + N' (1 ,''T4 RY used for allocation view'', ' + @p_PrevFactAllocReferencePeriod + ', ' + @p_FactAllocReferencePeriod + ', Null) ;'

PRINT @p_SQLCMD
EXEC sp_executesql @statement = @p_SQLCMD
