Really not the right place here, but OK. It would help to specify your db engine as well. It should go roughly like this: 
select * from tbl 
where coalesce(actual_start, projected_start, some_deep_past) <= curre
+nt_date 
and coalesce(actual_finish, projected_finish, some_far_future) >= curr
+ent_date
