Error: An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAV
- by brz dot net
I have to find the indentid from the status table based on below two conditions:
1. If there are more than one record having same indentid in status table and the same indentID has count1 in feasibilitystatus table then
       I don't want to display the record.
2. If there is only one record of indentid in status table and the same indentID has count0 in feasibilitystatus table then
       I don't want to display the record.
Query:
select distinct s.indentid
from status s 
where s.status='true'
 and s.indentid
  not in( select case when count(s.indentid)>1 then 
                      (select indentid from feasibilitystatus
                       group by indentid having count(indentid)>1)
                 else (select indentid from feasibilitystatus
                       group by indentid having count(indentid)>0)    
                 end as indentid from status)
Error:
An aggregate may not appear in the WHERE clause unless it is in a subquery 
contained in a HAVING clause or a select list, and the column being aggregated is 
an outer reference.
