It is a bit unclear what you expect to get.
If you need to get all published and finalized reports summed together,
and reported with the published and finalized, only one select will not
suffice. Maybe something like this:
create view myview as
(select department, employee_id, report_status, sum(reports)
reports
from logger.reports
group by department, employee_id, report_status
union all
select department, employee_id, 'all' as report_status,
sum(reports) reports
from logger.reports
group by department, employee_id )
Additional sorting may be required if you need the rows for published,
finalized and all to be near each other in the results.
