In SQL Server 2008, is it possible to create a column that can have a value inserted into it, but can never be updated? In other words, the column can have an initial value inserted into it, but once it contains a non-null value, it can never be changed. If possible, I would prefer to do it without using a trigger.
Thanks - Randy
