Answer 1

SELECT YEAR(date) as SalesYear, 
     MONTH(date) as SalesMonth, 
     SUM(Price) AS TotalSales 
    FROM Sales 
GROUP BY YEAR(date), MONTH(date) 
ORDER BY YEAR(date), MONTH(date) 

Answer 2

SELECT CONVERT(CHAR(7), SmallDateTime, 120) as Year_Month, 
     SUM(Price) 
    FROM Sales 
    GROUP BY CONVERT(CHAR(7), SmallDateTime, 120) 
    ORDER BY Year_Month

另一种解决方案是计算一个月的第一天

Select DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0) 
    , Sum(Price) 
From Sales 
Group By DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0)

试试这个

SELECT A.CAL_YEAR AS YEAR ,A.CAL_WEEK AS WEEK,SUM(B.SUM_OF_PROFIT) as profit FROM 
CALANDER A,SALES_FACT B WHERE A.DATE_ID=B.DATE_ID 
GROUP BY A.CAL_YEAR,A.CAL_WEEK;
