I want have a query with a column that is a hardcoded value not from a table, can this be done? I need it basically as a placeholder that I am going to come back to later a
The answers above are correct, and what I'd consider the "best" answers. But just to be as complete as possible, you can also do this directly in CF using queryAddColumn.
See http://www.cfquickdocs.com/cf9/#queryaddcolumn
Again, it's more efficient to do it at the database level... but it's good to be aware of as many alternatives as possible (IMO, of course) :)
