Получение ошибки с помощью Union all

Question

select cou_name as County_Name, count(*) as count 
from sdrp15_cosd 
where sd_code in (select sd_code from sdrp15_submission_log where QA_DATE IS null) 
union all 
select cou_name as County_Name, count(*) 
from sdrp15_cosd 
where sd_code in (select sd_code from sdrp15_submission_log where QA_DATE IS not null) 
GROUP BY COU_NAME; 

Я пытаюсь найти имена графств и для каждого округа. Я показываю общее количество, когда связанная таблица отображает связанный столбец с нулевым или не равным нулю.

Я получаю сообщение об ошибке:

not a single-group function
