This seems stupid but, I simply need a list of dates to be ordered with the most recent date at top. Using order by DESC doesn\'t seem to be working the way I w

    I'm guessing EventDate is a char or varchar and not a date otherwise your order by clause would be fine.

    You can use CONVERT to change the values to a date and sort by that

    SELECT * 
    FROM 
         vw_view 
    ORDER BY 
       CONVERT(DateTime, EventDate,101)  DESC
    

    The problem with that is, as Sparky points out in the comments, if EventDate has a value that can't be converted to a date the query won't execute.

    This means you should either exclude the bad rows or let the bad rows go to the bottom of the results

    To exclude the bad rows just add WHERE IsDate(EventDate) = 1

    To let let the bad dates go to the bottom you need to use CASE

    e.g.

    ORDER BY 
        CASE
           WHEN IsDate(EventDate) = 1 THEN CONVERT(DateTime, EventDate,101)
           ELSE null
        END DESC
