SQL Select to return a static list of values?

Question

Is there a way to perform a select and return a static list? Something like the following:

select * from ('CA', 'FB', 'FC')

It should return

CA
FB
FC

Answer 1

If you want each value on a separate row, you can use table constructor values():

select val
from (values ('CA'), ('FB'), ('FC')) as t(val)

If you wanted more columns, you would use tuples rather than singletons:

select val1, val2
from (values 
    ('CA', 'CB'), 
    ('FA', 'FB'),
    ('FC', 'FD') 
) as t(val1, val2)

Answer 2

Perhaps:

select 'CA'
union all
select 'FB'
union all
select 'FC'
