簡化重複的SQL Server查詢

我有一個重複性的SQL查詢來基於subaccounts/years，從subaccounts/years持有的金額列表中填充一個簡單的表，但這裏並沒有一對一的關係。輸出用於SSRS報告。簡化重複的SQL Server查詢

CREATE TABLE [dbo].[Results](
     [SchemeDescription] [varchar](50) NULL, 
     [SubAccountYear] [varchar](15) NULL, 
     [RowNumber] [int] NULL, 
     [2008] [money] NULL, 
     [2009] [money] NULL, 
     [2010] [money] NULL, 
     [2011] [money] NULL, 
     [2012] [money] NULL, 
     [2013] [money] NULL, 
     [2014] [money] NULL, 
     [2015] [money] NULL, 
     [2016] [money] NULL, 
     [2017] [money] NULL, 
     [2018] [money] NULL, 
     [2019] [money] NULL, 
     [2020] [money] NULL, 
     [Processed] [int] NULL 
) ON [PRIMARY] 
UPDATE res 
     SET 
      [2008] = res.[2008] + isnull(x.[2008],0) 
      ,[2009] = res.[2009] + isnull(x.[2009],0) 
      ,[2010] = res.[2010] + isnull(x.[2010],0) 
      ,[2011] = res.[2011] + isnull(x.[2011],0) 
      ,[2012] = res.[2012] + isnull(x.[2012],0) 
      ,[2013] = res.[2013] + isnull(x.[2013],0) 
      ,[2014] = res.[2014] + isnull(x.[2014],0) 
      ,[2015] = res.[2015] + isnull(x.[2015],0) 
      ,[2016] = res.[2016] + isnull(x.[2016],0) 
      ,[2017] = res.[2017] + isnull(x.[2017],0) 
      ,[2018] = res.[2018] + isnull(x.[2018],0) 
      ,[2019] = res.[2019] + isnull(x.[2019],0) 
      ,[2020] = res.[2020] + isnull(x.[2020],0) 
      ,processed = **1** 
     FROM [Results] res 
     INNER JOIN [Other_Income] as x 
      ON x.SubAccountYear = Cast(Cast(res.SubAccount AS Int)as Varchar(10)) + '¬' 
+ Cast (YEAR(res.Inception_Date)+ **1** as varchar(4)) 
       AND x.Processed = 0 
      WHERE res.RowNumber = 1

我必須重複10次以上的查詢，以確保所有的子帳戶年的分攤至適當的子帳戶，由星號所包圍的數字需要從1到枚舉至10

I」我確定還有另外一種方法，但它沒有解決。任何想法讚賞。

假設我正確理解你，你應該用一個存儲過程包裝你的更新語句，該存儲過程將處理後的值作爲一個變量。是這樣的：

CREATE PROCEDURE UpdateResults (
    @Processed int 
) 
AS 
UPDATE res 
    SET 
     [2008] = res.[2008] + isnull(x.[2008],0) 
     ,[2009] = res.[2009] + isnull(x.[2009],0) 
     ,[2010] = res.[2010] + isnull(x.[2010],0) 
     ,[2011] = res.[2011] + isnull(x.[2011],0) 
     ,[2012] = res.[2012] + isnull(x.[2012],0) 
     ,[2013] = res.[2013] + isnull(x.[2013],0) 
     ,[2014] = res.[2014] + isnull(x.[2014],0) 
     ,[2015] = res.[2015] + isnull(x.[2015],0) 
     ,[2016] = res.[2016] + isnull(x.[2016],0) 
     ,[2017] = res.[2017] + isnull(x.[2017],0) 
     ,[2018] = res.[2018] + isnull(x.[2018],0) 
     ,[2019] = res.[2019] + isnull(x.[2019],0) 
     ,[2020] = res.[2020] + isnull(x.[2020],0) 
     ,processed = @Processed 
    FROM [Results] res 
    INNER JOIN [Other_Income] as x 
     ON x.SubAccountYear = Cast(Cast(res.SubAccount AS Int)as Varchar(10)) + '¬' 
+ Cast (YEAR(res.Inception_Date)+ @Processed as varchar(4)) 
      AND x.Processed = 0 
     WHERE res.RowNumber = 1

然後就是執行它（也許在一個while循環）：

Declare @processed int = 1 
While @processed < 11 
begin 
    exec UpdateResults @processed 
    set @processed = @processed + 1 
end

感謝。我想知道我是否可以只使用SQL，而不是SP或循環。 – Anthony

存儲過程*只是sql ...這裏沒有魔法...... –
