Question

我需要一个查询，总计支出实际年初至今，平均年初至今（所有年份，我的平均年份），去年年初

我需要3个数据：实际YTD |平均年初至今|去年|

这是我到目前为止所做的：

select  SUM(Expenses)
        ,DATEADD(year, datediff(year,0,[Date]), 0) 
from    table1 
group by  
        DATEADD(year, datediff(year,0,[Date]), 0) 
)

Answer 1

试试这个：

DECLARE @currentYear int
SELECT @currentYear = DATEPART(year, GETDATE())

SELECT SUM(CASE WHEN DATEPART(year,[date]) = @currentYear 
    THEN Expenses ELSE 0 END) AS 'Actual YTD',
SUM(Expenses) / COUNT( DISTINCT DATEPART(year,[date])) AS 'Average YTD',
SUM(CASE WHEN DATEPART(year,[date]) = @currentYear -1 
    THEN Expenses ELSE 0 END) AS 'Last Year YTD'

FROM Table1

Answer 2

试试这个

select 

    AVG(case when 
        [date]>=DATEADD(year, datediff(year,0,getDate())-1, 0)  and 
        [date]<DATEADD(year, datediff(year,0,getDate()), 0) 
        then Expenses end) 
        as average_ytd,

    sum(case when 
        [date]>=DATEADD(year, datediff(year,0,getDate())-1, 0)  and 
        [date]<DATEADD(year, datediff(year,0,getDate()), 0) 
        then Expenses else 0 end) 
        as actual_ytd,

    sum(case when 
        [date]>=DATEADD(year, datediff(year,0,getDate())-2, 0)  and 
        [date]<DATEADD(year, datediff(year,0,getDate())-1, 0) 
        then Expenses else 0 end) 
        as lat_year_ytd
from
    table1

SQL查询总结值实际年份和平均年终数
