One big advantage of a const table (I have always called mine control) is that you can very easily get the values out of this table (assuming there are not very many columns and ONLY 1 row). just add a cross join to your table and you are all set.
declare @Code int = 10
select * from myTable
where myTable.Code = @Code
becomes
select * from MyTable
cross join control c
where MyTable.Code = c.Code
