减去返回多于1行的两个SQL子查询的结果

Question

我想从两个子查询中减去结果，但我想返回多于1行，因为我想查看总调用以及它们在特定日期范围内的差异，下面的代码会给我一个错误：“子查询返回的值超过1个值，当子查询跟随=，！=，<,<,< =，>，> =或当子查询用作表达式“。希望你能帮助我。请注意，这是存储过程的一部分。先谢谢你。

SELECT distinct 

c.reporting as 'Agent_ID' 
,count(a.pkey) as 'Total_Calls_Handled' 
,a.MidnightStartDate as 'Call_Start_Time' 
,datename(dw,a.midnightstartdate) as 'Week_day' 
,a.[queue] 

into #temp3 
FROM t1 a 
join t2 b 
on a.FKAgent = b.fkagent 
join t3 c 
on a.agent = c.reporting 
where a.agent in (

    '132568' 
,'116308' 
,'132083' 
,'113737' 

) 

and convert(date, midnightstartdate) BETWEEN '08/29/16' AND '08/30/19' 
group by c.Reporting,a.MidnightStartDate,a.[queue] 


SELECT distinct b.[Week_Day], a.[Queue],[Total ACD Calls], [Total ACD Calls Handled], count([total_calls_handled]) as 'Total ACD Calls Handledby Agent', 

(select ((select [total acd calls handled] from #temp2) - 
(select count([total_calls_handled]) from #temp3))) as 'OperatorsCalls' 

INTO #Temp4 
FROM #Temp2 a 
JOIN #Temp3 b 
ON a.[Queue] = b.[Queue] 
GROUP BY [Total ACD Calls], [Total ACD Calls Handled], b.[Week_Day] , a.[Queue],[total_calls_handled]

这是我最好的一击，它没有一个工作的SQL小提琴，所以如果它不是现货道歉。基本上，您需要在加载数据之前创建临时表，执行计算（然后可以保持多行格式），然后将其加入最终的＃temp4表中的最终插入。

SELECT distinct 

c.reporting as 'Agent_ID' 
,count(a.pkey) as 'Total_Calls_Handled' 
,a.MidnightStartDate as 'Call_Start_Time'

,a.[queue] 

into #temp3 
FROM t1 a 
join t2 b 
on a.FKAgent = b.fkagent 
join t3 c 
on a.agent = c.reporting 
where a.agent in (

'132568'

) 

and convert(date, midnightstartdate) BETWEEN '08/29/16' AND '08/30/19' 
group by c.Reporting,a.MidnightStartDate,a.[queue] 

--new temp table to load temp3 counts 
SELECT 
    Count(total_calls_handled) as total_calls_handled_count, 
    queue

GROUP BY T2.Queue,T2.[Total acd calls handled],T3.total_calls_handled_count
