Experts,
I have a query that looks like the code below.
I would like to calculate the Median of Price in addition to the Max, Min and Avg.
How would I go about doing that with a query of this form?

Thanks in advance.

SELECT          a.productid
            , Count(a.productID) as Cnnt
            , Max(a.Price) as 'MaxPrice'
            , MIN(a.Price) as 'MinPrice'
            , CONVERT(decimal(11,0),CAST(Avg(a.Price) as decimal) ) as 'AvgPrice'
            -- Want to have Median price here

FROM
      (

      (
      select  productid, [End Price] as 'Price'
      from Table1
      where productid is not null
      )
      
      UNION ALL
      
      (
      select  productid, [Sale Amount] as 'Price'
      from Table2
      where productid is not null
      )

      ) as a

Thanks I've seen that page and some on MSDN.
However, I now see that page links to a 2014 update that gave me a nice solution for SQL Server 2012.
