How can I create a blank/hardcoded column in a sql query?

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 and fill in.

example:

SELECT
hat,
shoe,
boat,
somevalue = 0 as placeholder
FROM
objects

then I would loop through this query later and fill in the placeholder

in this example someValue is not a field in objects, I need to fake it. I am doing this in coldfusion and using two datasources to complete one query. I have tried the space() function but have been unable to get it to work.

Thanks.
