If I'm understanding you correctly, you can't do what you want with
a single aggregate function call, because that will only give you
one result.

Consider something like

select
    sum(case when logic = '1' then 1 else 0 end),
    sum(case when logic = '2' then 1 else 0 end),
    sum(case when logic = '3' then 1 else 0 end)
from ...

I also wonder whether you aren't reinventing the notion of GROUP BY.
F'r instance

select logic, count(*) from ... group by logic;
