    @EndDate   = '2017-03-01';

SELECT  
    /*is there a way for me to get the year of months based on the parameter dates*/
    /*DATEPART(YEAR, DATEADD(YEAR, x.number, @StartDate)) AS Year,*/ 
    DATEPART(MONTH, DATEADD(MONTH, x.number, @StartDate)) AS Month,
    DATENAME(MONTH, DATEADD(MONTH, x.number, @StartDate)) AS MonthName
FROM    
    master.dbo.spt_values x

试试这个：

SELECT YEAR(y.dt) AS Year,
       MONTH(y.dt) AS Month,
       DATENAME(MONTH, y.dt) AS MonthName
FROM    master.dbo.spt_values x
CROSS APPLY (SELECT DATEADD(MONTH, x.number, @StartDate)) AS y(dt)
WHERE   x.type = 'P'        
AND     x.number <= DATEDIFF(MONTH, @StartDate, @EndDate)
