Question

我有以下查询，用于计算年初至今和上一年。我该如何优化呢？

代替使用CTE，您可以使用临时表重新组织代码。在Temps上放置正确的索引也会加快速度。

例如：

    drop table if exists #cumulative_sum_for_ytd;

    SELECT T.*,
       T1.QTY_UoM_YTD,t1.QTY_YTD,t1.AMOUNT_LCPNV
INTO #cumulative_sum_for_ytd
FROM tmp.FACT_DC  T
CROSS APPLY
(
    SELECT SUM(QTY_UoM) AS QTY_UoM_YTD,SUM(QTY) AS QTY_YTD, SUM(PNV_LC)as AMOUNT_LCPNV
    FROM tmp.FACT_DC 
    WHERE [Delivery_Year]=T.[Delivery_Year]
        AND convert(date,Delivery_Year+'-'+ Delivery_month+'-'+ [Invoicing_Day])<=convert(date,T.Delivery_Year+'-'+ t.Delivery_month+'-'+ t.[Invoicing_Day])
        AND [Sales_Organization]=T.Sales_Organization
        AND[Sales_Product_Name_N3]=T.Sales_Product_Name_N3
        AND[Sales_Product_Name_N2]=T.[Sales_Product_Name_N2]
        AND[Sales_Product_Name_N1]=T.[Sales_Product_Name_N1]
        AND[Market_Segment_Name_N2]=T.[Market_Segment_Name_N2]
        AND[Doc_Currency]=T.Doc_Currency
        AND[User_Name_N1]=T.User_Name_N1
        AND[Engineer_Code]=T.Engineer_Code
        AND[User_Name_N2]=T.User_Name_N2
        AND[Bill_To_Customer_Code]=T.Bill_To_Customer_Code
        AND[User_Country_Code]=T.User_Country_Code
        AND[User_N3_Country_Name]=T.User_N3_Country_Name
) T1

等...

优化查询以计算年初至今和上一年迄今
