Question

我有一个Fact_Actuals yable，新列“Segment_Id”。

我需要将DimsegmentMaster中的段ID插入Fact_Actuals。

链接是SegmentMaster和Source Table列。

链接与FactTable是下面的源表列的度量。

请提供更新查询，因为我的以下查询不合适。

UPDATE Application_DB.[cdw].[Fact_Actuals] 
  set segment_sid =
  (SELECT c.SID
   FROM Application_DB.[cdw].[Fact_Actuals] b
   inner join Source_DB.STA.SourceTable a
     ON  convert(decimal(20,10),LTRIM(RTRIM(a.[K308]))) = b.NetExternalSales
     and convert(decimal(20,10),LTRIM(RTRIM(a.[K203]))) = b.Quantity_CON
     and convert(decimal(20,10),LTRIM(RTRIM(a.[K202]))) = b.Quantity_KG
   inner join Application_DB.cdw.DimSegmentMaster c
     ON RTRIM(a.[C005])=c.SegmentOriginal
  )

Answer 1

试试这个：

UPDATE b  
set segment_sid = c.sid
FROM Application_DB.[cdw].[Fact_Actuals] b
inner join Source_DB.STA.SourceTable a
ON 
    convert(decimal(20,10),LTRIM(RTRIM(a.[K308])))=b.NetExternalSales
    and convert(decimal(20,10),LTRIM(RTRIM(a.[K203])))=b.Quantity_CON
    and convert(decimal(20,10),LTRIM(RTRIM(a.[K202])))=b.Quantity_KG
inner join Application_DB.cdw.DimSegmentMaster c
ON RTRIM(a.[C005])=c.SegmentOriginal

使用第3个表
