不使用透視功能的SQL數據透視表

Question

我需要將表格從標準表格轉換爲更加概括的版本。行應基於2013年或2014年。我正在考慮使用一個關鍵點，但我不相信它的必要性。下面的代碼失敗，因爲我剛剛創建的列的功能組是有辦法解決這個問題嗎？

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] 

最終的結果應該是：

所需的輸出

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

不能按同一 '級別' 創建一個別名，但你應該能夠以相同的表情分組，但也許你只是想按年分組？ （如果是的話，也許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 

由於您沒有提供任何樣本數據或表我無法測試它，但它應該工作。

或者，也許你想要聚合行：

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];
