Where clause condition on aggregate functions [duplicate]

Answer 1

The example returns count per user, per IssueType.

;
with
q_00 as (
select
      is_issue_no
    , is_assigned_user_id 
    , case
          when is_issue_no between  1 and 10 then 'A'
          when is_issue_no between 11 and 14 then 'B'
          else  'C'  
      end as IssueType
from Issues 
)
select
      us_logon_name
    , IssueType
    , count(1) as cnt
from q_00  as a
join users as u on a.is_assigned_user_id = u.us_user_id
group by us_logon_name, IssueType
order by us_logon_name, IssueType ;
