You can try using the CASE statement as mentioned below:



        WHEN DateA>= DateB AND DateA>= DateC THEN DateA

        WHEN DateB>= DateA AND DateB>= DateC THEN DateB

        WHEN DateC>= DateA AND DateC>= DateB THEN DateC

        ELSE                                        DateA

    END AS Most_Recent_Date
