不使用透视功能的SQL数据透视表

Question

我需要将表格从标准表格转换为更加概括的版本。行应基于2013年或2014年。我正在考虑使用一个关键点，但我不相信它的必要性。下面的代码失败，因为我刚刚创建的列的功能组是有办法解决这个问题吗？

CODE

CREATE VIEW -- select * from 
    [03_rdm].[AR_LedgerByInvoice] 
as 
select [EY_Business_Unit] 
     ,(Case when [AR_Fiscal Year] = 2014 then 'AR_Outstanding_Amount (CY)' else 'AR_Outstanding_Amount (PY)' end) [Aging_Bucket] 
     , [AR_1-30 Days Past Due] 
     , [AR_31-60 Days Past Due] 
     , [AR_61-90 Days Past Due] 
FROM [02_cdm].[0040_AR_InvoiceSummary_2013_2014] 
GROUP BY [Aging_Bucket] 

最终的结果应该是：

所需的输出

Business Unit Aged Bucket    [AR_1-30 Days] [AR_31-60 Days] [AR_61-90 Days] Total 
100 `   AR_Outstanding_Amount (CY) x    xx    xxx    xxxx 
100    AR_Outstanding_Amount (PY) x    xx    xxx    xxxx 

Answer 1

不能按同一 '级别' 创建一个别名，但你应该能够以相同的表情分组，但也许你只是想按年分组？ （如果是的话，也许GROUP BY [AR_Fiscal Year]是你真正想要的）：

CREATE VIEW -- select * from 
    [03_rdm].[AR_LedgerByInvoice] 
as 
select [EY_Business_Unit] 
     ,(Case when [AR_Fiscal Year] = 2014 then 'AR_Outstanding_Amount (CY)' else 'AR_Outstanding_Amount (PY)' end) [Aging_Bucket] 
     , [AR_1-30 Days Past Due] 
     , [AR_31-60 Days Past Due] 
     , [AR_61-90 Days Past Due] 
FROM [02_cdm].[0040_AR_InvoiceSummary_2013_2014] 
GROUP BY 
    [EY_Business_Unit], 
    CASE WHEN [AR_Fiscal Year] = 2014 THEN 'AR_Outstanding_Amount (CY)' ELSE 'AR_Outstanding_Amount (PY)' END 

由于您没有提供任何样本数据或表我无法测试它，但它应该工作。

或者，也许你想要聚合行：

select [EY_Business_Unit] 
     ,(Case when [AR_Fiscal Year] = 2014 then 'AR_Outstanding_Amount (CY)' else 'AR_Outstanding_Amount (PY)' end) [Aging_Bucket] 
     , SUM([AR_1-30 Days Past Due]) 
     , SUM([AR_31-60 Days Past Due]) 
     , SUM([AR_61-90 Days Past Due]) 
FROM [0040_AR_InvoiceSummary_2013_2014] 
GROUP BY 
[EY_Business_Unit] 
     ,(Case when [AR_Fiscal Year] = 2014 then 'AR_Outstanding_Amount (CY)' else 'AR_Outstanding_Amount (PY)' end) 
order by [EY_Business_Unit];
