How do I set a column to return a value in a select statement

Question

So if i do a statement such as

Select column1, column2
from dbo.table

How would i return column1 as the actual data and column2 as a fixed value, if i wanted to have column 2 to always show the same value.Im building an output file and need to put in some predefined results.

Column1         Column2
-------         -------
dog             A
cat             A
bird            A

thanks a lot
