Question

我有以下查询，但我需要能够为列出的每个列提供“总数”。

有人可以帮忙吗？

这是我的sql：

select PartnerAbbrev,
    count(TrafficPreApplications.Id) as Hits,
    SUM(Case WHEN TrafficPreApplications.laststep = 1 THEN 1 ELSE 0 END) as Hit1_1,
    SUM(Case WHEN  TrafficPreApplications.laststep = 2 THEN 1 ELSE 0 END) as Hit1_2,
    SUM(Case WHEN TrafficPreApplications.laststep = 3 THEN 1 ELSE 0 END) as Hit1_3,
    SUM(Case WHEN TrafficPreApplications.laststep = 4 THEN 1 ELSE 0 END) as Hit1_4,
    SUM(Case WHEN  TrafficPreApplications.laststep = 5 THEN 1 ELSE 0 END) as Hit1_5,
    SUM(Case WHEN TrafficPreApplications.laststep = 6 THEN 1 ELSE 0 END) as Hit1_6,
    SUM(Case WHEN  TrafficPreApplications.laststep = 7 THEN 1 ELSE 0 END) as Hit1_7,
    SUM(Case WHEN  TrafficPreApplications.laststep = 9 THEN 1 ELSE 0 END) as Hit1_9,
    SUM(Case WHEN  TrafficPreApplications.laststep = 999 THEN 1 ELSE 0 END) as Hit1_999,
    SUM(Case WHen  TrafficHitId is not null THEN 1 ELSE 0 END) as Today_PreApp
from TrafficPreApplications full join TrafficHits on TrafficPreApplications.TrafficHitId = traffichits.Id
 join TrafficPartners on TrafficPartners.Id = TrafficHits.TrafficPartnerId
 join Partners on Partners.Id = TrafficPartners.PartnerId
 group by PartnerAbbrev

您不需要完全加入，无论如何都会从TrafficHits移除TrafficPreApplications行。

select Partners.Id,
       PartnerAbbrev,
       count(TrafficPreApplications.Id) as Hits,
       SUM(Case WHEN TrafficPreApplications.laststep = 1 THEN 1 ELSE 0 END) as Hit1_1,
       ... 
from TrafficPreApplications 
right join TrafficHits on TrafficPreApplications.TrafficHitId = traffichits.Id
join TrafficPartners on TrafficPartners.Id = TrafficHits.TrafficPartnerId
join Partners on Partners.Id = TrafficPartners.PartnerId
group by Partners.Id, PartnerAbbrev
union all
    select max(Partners.Id)+1,
       'total',
       count(TrafficPreApplications.Id) as Hits,
       SUM(Case WHEN TrafficPreApplications.laststep = 1 THEN 1 ELSE 0 END) as Hit1_1,
       ... 
from TrafficPreApplications 
right join TrafficHits on TrafficPreApplications.TrafficHitId = traffichits.Id
join TrafficPartners on TrafficPartners.Id = TrafficHits.TrafficPartnerId
join Partners on Partners.Id = TrafficPartners.PartnerId
order by 1,2

需要知道如何在SQL查询中总计总和
