    SELECT S.year as [Year],
    MONTH(S.date) as [Month],
    SUM(S.Value) as [Value]
    FROM Sale S
    WHERE S.date BETWEEN @StartDate and @EndDate
    GROUP BY S.year, MONTH(S.date) 
    ORDER BY [Year], [Month] 
END


EXEC dbo.GetTotalByDate @StartDate = '01/01/2013', @EndDate = '01/01/2014'

    SELECT DATEPART(YEAR, date)as [Year],
    MONTH(date) as [Month],
    SUM(Value) as [Value]
    FROM Sale 
    GROUP BY DATEPART(YEAR, date), MONTH(date) 
END

EXEC dbo.GetTotalAmount
