Sql oracle销售总额查询

在我目前工作的一个项目中，我们需要获得每月、每季度和每年的客户销售总额。我尝试了如下所示的查询，得到了今天的正确结果。但我还需要去年的销售业绩。（去年的月销售额是该月的总和）

我真的需要一个快速修复这里，感谢每一个评论提前

SELECT    
CUSTOMER,        
PRODUCT,
EXTRACT(MONTH FROM DAY) MONTH,
EXTRACT(YEAR FROM DAY) YEAR,
SUM(
    CASE
        WHEN DAY >= TRUNC(sysdate,'MM')
        THEN DAILY_SALE
        ELSE 0
    END) AS MONTH_SALE,
SUM(
    CASE
        WHEN DAY >= add_months(TRUNC(sysdate,'MM'),-3)
        AND DAY < TRUNC(sysdate,'MM')
        THEN DAILY_SALE
        ELSE 0
    END) AS THREE_MONTHL_SALE,
SUM(
    CASE
        WHEN DAY >= add_months(TRUNC(sysdate,'MM'),-6)
        AND DAY < TRUNC(sysdate,'MM')
        THEN DAILY_SALE
        ELSE 0
    END) AS SIX_MONTHL_SALE,
SUM(
    CASE
        WHEN DAY >= add_months(TRUNC(sysdate,'MM'),-12)
        AND DAY < TRUNC(sysdate,'MM')
        THEN DAILY_SALE
        ELSE 0
    END) AS YEAR_SALE

这可能有助于满足您的需求。。。它给出了每个月、每个季度以及全年、每年的总数。如果您想要特定年份，我建议添加“where EXTRACT（YEAR FROM DAY）=2012”或类似的条款

我相信这是你要求的，但这与你提供的样品不同。您提供的示例提供了3个月、6个月、9个月和12个月的跟踪销售，这与季度年份和月份不同。不过，如果需要的话，你可以很容易地混合搭配

SELECT    
CUSTOMER,        
PRODUCT,
EXTRACT(YEAR FROM DAY) YEAR,
SUM(DAILY_SALE) as YEAR_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '01' THEN DAILY_SALE ELSE 0 END) AS MONTH_01_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '02' THEN DAILY_SALE ELSE 0 END) AS MONTH_02_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '03' THEN DAILY_SALE ELSE 0 END) AS MONTH_03_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '04' THEN DAILY_SALE ELSE 0 END) AS MONTH_04_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '05' THEN DAILY_SALE ELSE 0 END) AS MONTH_05_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '06' THEN DAILY_SALE ELSE 0 END) AS MONTH_06_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '07' THEN DAILY_SALE ELSE 0 END) AS MONTH_07_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '08' THEN DAILY_SALE ELSE 0 END) AS MONTH_08_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '09' THEN DAILY_SALE ELSE 0 END) AS MONTH_09_SALES,
SUM(CASE WHEN TO_CHAR(DAY, 'MM') = '10' THEN DAILY_SALE ELSE 0 END) AS MONTH_10_SALES,

SUM(
    CASE
        WHEN TO_CHAR(DAY, 'MM') IN ('10', '11', '12')
        THEN DAILY_SALE
        ELSE 0
    END) AS Q4_SALES,
SUM(
    CASE
        WHEN TO_CHAR(DAY, 'MM') IN ('07', '08', '09')
        THEN DAILY_SALE
        ELSE 0

这可能不是您所需要的，但可能会有所帮助：

select a.Product_Name, 
d.Company_Name, 
to_char(Order_Date, 'YYYY') as OrderYear,
sum(case to_char(c.Order_Date, 'Q') when '1' 
    then b.Unit_Price*b.Quantity*(1-b.Discount) else 0 end) "Qtr 1",
sum(case to_char(c.Order_Date, 'Q') when '2' 
    then b.Unit_Price*b.Quantity*(1-b.Discount) else 0 end) "Qtr 2",
sum(case to_char(c.Order_Date, 'Q') when '3' 
    then b.Unit_Price*b.Quantity*(1-b.Discount) else 0 end) "Qtr 3",
sum(case to_char(c.Order_Date, 'Q') when '4' 
    then b.Unit_Price*b.Quantity*(1-b.Discount) else 0 end) "Qtr 4" 
from Products a

您的查询有什么问题？您能提供您正在寻找的示例结果吗？您的查询将根据当前日期为您提供三个月的分组。。。仅当您在季度结束月份运行查询时，这将等同于公司季度。所以，我的问题是，当你说“季度”时，你的意思是1-2-3月总是第1季度，还是你需要它来像你的查询那样移动？
