Question

我使用以下SQL查询：

select 
    FilteredSystemUser.systemuserid,
    FilteredPhoneCall.regardingobjectid 
from 
    FilteredPhoneCall 
Inner Join 
    FilteredSystemUser on FilteredSystemUser.systemuserid in (FilteredPhoneCall.createdby)
Inner Join 
    FilteredLead on FilteredLead.leadid = FilteredPhoneCall.regardingobjectid
where 
    DateDiff(d, FilteredPhoneCall.createdon, GETDATE()) = 0 
    and FilteredLead.statecode = 0 
    and FilteredLead.ownerid = FilteredSystemUser.systemuserid
    and FilteredPhoneCall.statecode = '1' 
    and FilteredPhoneCall.regardingobjecttypecode = 4
    and FilteredPhoneCall.createdby in ('c2dd1ddc-0374-e611-80dc-00155d3d1992', '53cfbe3a-a09a-e611-80df-00155dce24d0')

并获得以下输出

在这里，我对于相同系统用户的 97C29D24-BEE2-E611-80F1-00155DCE24EF，091B1CAB-C2E2-E611-80F1-00155DCE24EF 有两个条目。所以我需要将其视为单个条目并获得除此之外的计数，两个系统用户有另外两个ID。

我期待上面的输出

要在此处计算列引用的不同值的计数... SQL: Count distinct values from one column based on multiple criteria in other columns

对于您的情况，请尝试：

   select 
        FilteredSystemUser.systemuserid,
        Count(DISTINCT FilteredPhoneCall.regardingobjectid ) as NoofCall
    from 
        FilteredPhoneCall 
    Inner Join 
        FilteredSystemUser on FilteredSystemUser.systemuserid in (FilteredPhoneCall.createdby)
    Inner Join 
        FilteredLead on FilteredLead.leadid = FilteredPhoneCall.regardingobjectid
    where 
        DateDiff(d, FilteredPhoneCall.createdon, GETDATE()) = 0 
        and FilteredLead.statecode = 0 
        and FilteredLead.ownerid = FilteredSystemUser.systemuserid
        and FilteredPhoneCall.statecode = '1' 
        and FilteredPhoneCall.regardingobjecttypecode = 4
        and FilteredPhoneCall.createdby in ('c2dd1ddc-0374-e611-80dc-00155d3d1992', '53cfbe3a-a09a-e611-80df-00155dce24d0')
    Group by FilteredSystemUser.systemuserid

Answer 2

您可以使用count（）和group by来实现此目的。

select      COUNT(DISTINCT FilteredPhoneCall.regardingobjectid ) as NoofCall
            ,FilteredSystemUser.systemuserid
from        FilteredPhoneCall 
inner Join  FilteredSystemUser
on          FilteredSystemUser.systemuserid in(FilteredPhoneCall.createdby)
Join        FilteredLead
on          FilteredLead.leadid = FilteredPhoneCall.regardingobjectid
where       DateDiff(d, FilteredPhoneCall.createdon, GETDATE()) = 0 
    and     FilteredLead.statecode = 0 and FilteredLead.ownerid = FilteredSystemUser.systemuserid
    and     FilteredPhoneCall.statecode = '1' and FilteredPhoneCall.regardingobjecttypecode = 4
    and     FilteredPhoneCall.createdby in ('c2dd1ddc-0374-e611-80dc-00155d3d1992','53cfbe3a-a09a-e611-80df-00155dce24d0')
    and     FilteredSystemUser.systemuserid in ('c2dd1ddc-0374-e611-80dc-00155d3d1992','53cfbe3a-a09a-e611-80df-00155dce24d0')
   GROUP BY FilteredSystemUser.systemuserid

尝试这个

;with CTE 
      AS (
    select 
        FilteredSystemUser.systemuserid,
        FilteredPhoneCall.regardingobjectid 
    from 
        FilteredPhoneCall 
    Inner Join 
        FilteredSystemUser on FilteredSystemUser.systemuserid in (FilteredPhoneCall.createdby)
    Inner Join 
        FilteredLead on FilteredLead.leadid = FilteredPhoneCall.regardingobjectid
    where 
        DateDiff(d, FilteredPhoneCall.createdon, GETDATE()) = 0 
        and FilteredLead.statecode = 0 
        and FilteredLead.ownerid = FilteredSystemUser.systemuserid
        and FilteredPhoneCall.statecode = '1' 
        and FilteredPhoneCall.regardingobjecttypecode = 4
        and FilteredPhoneCall.createdby in ('c2dd1ddc-0374-e611-80dc-00155d3d1992', '53cfbe3a-a09a-e611-80df-00155dce24d0') )

        select count(CTE.systemuserid) as myCOUNT,CTE.systemuserid,CTE.regardingobjectid from CTE
        group by  CTE.systemuserid,CTE.regardingobjectid
