SQL MAX of multiple columns?

Question

How do you return 1 value per row of the max of several columns:

TableName

I need to return something like this:

[Number, Most_Recent_Date, Cost]

Query?

Here is another nice solution for the Max functionality using T-SQL and SQL Server

SELECT [Other Fields],
  (SELECT Max(v) 
   FROM (VALUES (date1), (date2), (date3),...) AS value(v)) as [MaxDate]
FROM [YourTableName]
