Trivial RowVersion Question Is there a method or syntax that would allow a table that just has a rowversion/timestamp column to be filled with data?

CREATE TABLE [dbo].[TimeStamp_Test]([row_version] [timestamp] NOT NULL)
I'm not sure why you would need this but yes it is possible.

Insert into [dbo].[TimeStamp_Test] default values;


Or 

Insert into [dbo].[TimeStamp_Test] values (default);


To do multiple rows you can use merge.
