       sum(IIF(r.Result = 0, 1, 0)) as CountResultNo
from TblAquestion q
left join TblUserResult r on r.AQcode_fk = q.AQcode
group by q.AQcode, q.AQdescribe

Answer 2

select aqcode,aqdescribe,sum(Cno),sum(Cyes) from
(
select aqcode,aqdescribe,'0' as Cno,count(result) as Cyes
from TblAquestion aq,TblUserResult r
where aq.aqcode=r.aqcode and r.result='1'
group by aqcode,aqdescribe
Union
select aqcode,aqdescribe,count(result) as Cno,'0' as Cyes
from TblAquestion aq,TblUserResult r
where aq.aqcode=r.aqcode and r.result='0'
