Rollup-Funktion - NULL ersetzen

Das ROLLUP setzt ein null in der Summenzeile. Wenn Sie das also ersetzen möchten, würde ich vorschlagen, Ihre vorhandene Abfrage zu nehmen und sie in eine Unterabfrage zu stellen und dann einen CASE zu verwenden auf NAME um die null zu ersetzen zu Total .

Ihr Code wird ungefähr so ​​aussehen:

select 
  case when name is null then 'Total' else name end Name,
  sum(Activated) Activated,
  sum(Deactivated) Deactivated
from
(
  select 
    case 
      when (upper(m.email) like '%max.com') then 'MAX'
      when (upper(m.email) like '%tax.com') then 'TAX'
      else 'OTHER'
    end Name, 
  SUM(case when substring(convert(varchar(8),n.created_on,112),1,6) = '201209' then 1 else 0         end) 'Activated',
  SUM(case when substring(convert(varchar(8),m.LastLockoutDate,112),1,6)='201209' then 1 else 0              end) 'Deactivated'
  from membership.user_details d
  inner join membership.aspnet_membership m 
    on m.userid = d.userid
  inner join membership.user_notes n 
    on n.userid = d.userid
    and n.CREATED_ON = (select min(created_on) 
                        from membership.user_notes 
                        where userid = n.userid
                          and note = 'received.')  
  where approved = 1
  group by case when (upper(m.email) like '%max.com') then 'MAX'
        when (upper(m.email) like '%tax.com') then 'TAX'
        else 'OTHER' end     
) src
group by name with rollup

Wenn Sie Ihre Abfrage nicht in eine Unterabfrage einschließen, können Sie Folgendes verwenden:

select
   case when 
     (case 
        when (upper(email) like '%max.com') then 'MAX'
        when (upper(email) like '%tax.com') then 'TAX'
        else 'OTHER'
      end) is null then 'Total'
      else case 
        when (upper(email) like '%max.com') then 'MAX'
        when (upper(email) like '%tax.com') then 'TAX'
        else 'OTHER'
      end end Name,
  SUM(case when substring(convert(varchar(8),n.created_on,112),1,6) = '201209' then 1 else 0 end) 'Activated',
  SUM(case when substring(convert(varchar(8),m.LastLockoutDate,112),1,6)='201209' then 1 else 0 end) 'Deactivated'
from membership.user_details d
inner join membership.aspnet_membership m 
  on m.userid = d.userid
inner join membership.user_notes n 
  on n.userid = d.userid
  and n.CREATED_ON = (select min(created_on) 
                     from membership.user_notes 
                     where userid = n.userid
                       and note = 'received.')  
where approved = 1
group by case when (upper(m.email) like '%max.com') then 'MAX'
        when (upper(m.email) like '%tax.com') then 'TAX'
        else 'OTHER' end with rollup
