Question

我需要一些帮助。我想知道我的系统中这些列的激活，停用和用户总数。当前输出包括NAME列中的名称两次输出，如下所示，包括NULLS。我想消除NULL并获得每列的子总数。希望我能得到一些帮助。

  Current output:
- NAME   Activated  Deactivated 
- MAX     25          NULL
- MAX     NULL         5
- TAX     40          NULL
- TAX     NULL         10

    Desired output:
  - NAME   Activated  Deactivated 
   - MAX     25          5  
  - TAX     40          10
   -Total    65          15

感谢。

    case 
        when (upper(m.email) like '%max.com') then 'MAX'
        when (upper(m.email) like '%tax.com') then 'TAX'
        else 'OTHER'
        end Name, count(*) 'Activated', null 'Deactivated'

    membership.user_details d

        )
        and substring(convert(varchar(8),n.created_on,112),1,6) = '201209'
where 
    approved = 1
group by

Answer 1

分别将null 'Deactivated'和null 'Activated'更改为0'Deactivated'和0'Activated'，然后执行GROUP BY Name WITH ROLLUP

Answer 2

您应该能够将其合并为一个SELECT：

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 = 'SAAR 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

此新版本使用带有CASE表达式的聚合函数来获取总Activated和Deactivated。 CASE 检查每个查询使用的日期。

然后，如果要包含总行，可以使用GROUP BY with ROLLUP
