SQL 查询，需要有关所需输出的帮助

Question

请多多包涵，因为我刚刚开始深入研究 SQL 报告，这与仅转储数据相比是一个巨大的飞跃。

这里是表模式的简要说明。 表名：通话记录 字段：callid、tracker、recvddate、callsource

我已经成功使用了这个简单的分组查询

Select
    right('00' + rtrim(Datepart(ww, recvddate)),2) week,
    Tracker,
    count(callsource) as [Email Tickets]
from
    calllog

where datepart(year,recvddate) >= '2017' and callsource = 'email'
group by right('00' + rtrim(Datepart(ww, recvddate)),2),Tracker
order by 2,1

这给了我：

我正在尝试生成一个报告，其中我将每个调用源类型的记录数量计算为结果查询中它们自己的列。

这是我尝试过的：

Select
    right('00' + rtrim(Datepart(ww, c1.recvddate)),2) week,
    c1.Tracker,
    count(c1.callsource) as [Email Tickets],
    c2.[Queue Tickets]
from
    calllog c1
inner join
(
    Select
        right('00' + rtrim(Datepart(ww, recvddate)),2) week,
        Tracker,
        count(callsource) as [Queue Tickets]
    from
        calllog
    where datepart(year,recvddate) >= '2017' and callsource = 'phone'
    group by right('00' + rtrim(Datepart(ww, recvddate)),2),Tracker
) c2 
on c1.callid = c2.callid

where datepart(year,recvddate) >= '2017' and callsource = 'email'
group by right('00' + rtrim(Datepart(ww, recvddate)),2),Tracker
order by 2,1

但我收到以下错误。我尝试更改引用列的方式，但我尝试过的没有任何效果。

感谢任何建议。

更新：

在@Simon 的帮助下，我能够提出我正在寻找的这个查询。

SELECT      A.[week] as [Week],
            A.tracker as Tracker,
            B.Tickets as [Queue Tickets],
            C.Tickets as [Email Tickets],
            A.Tickets as [Total Tickets]
FROM        (SELECT RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2) [week],
                    Tracker,
                    COUNT(callid) as Tickets
             FROM   calllog
             WHERE DATEPART(year,recvddate) >= '2017' and tracker = 'djtaylor'
             GROUP BY RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2), Tracker) as A

INNER JOIN  (SELECT RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2) [week],
                    Tracker,
                    COUNT(callid) as Tickets
             FROM   calllog
             WHERE DATEPART(year,recvddate) >= '2017' and callsource = 'queue'
             GROUP BY RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2), Tracker) as B ON A.[week] = B.[week]
                                                                                    AND A.Tracker = B.Tracker
INNER JOIN  (SELECT RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2) [week],
                    Tracker,
                    COUNT(callid) as Tickets
             FROM   calllog
             WHERE DATEPART(year,recvddate) >= '2017' and callsource = 'email'
             GROUP BY RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2), Tracker) as C ON A.[week] = C.[week]
                                                                                    AND A.Tracker = C.Tracker
ORDER BY 2,1

我想这就是你想要的：

Select
    right('00' + rtrim(Datepart(ww, recvddate)),2) [week],
    Tracker,
    callsource,
    count(callid) as [Email Tickets]
from
    calllog

where datepart(year,recvddate) >= '2017' and callsource = 'email'
group by right('00' + rtrim(Datepart(ww, recvddate)),2), Tracker, callsource
order by [week], Tracker

好的。我想这就是你想要的：

SELECT      A.[week] as [Week],
            A.tracker as Tracker,
            A.callsource,
            A.Tickets as CallSourceTickets,
            B.Tickets CallCenterTickets
FROM        (SELECT RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2) [week],
                    Tracker,
                    callsource,
                    COUNT(callid) as Tickets
             FROM   calllog
             WHERE DATEPART(year,recvddate) >= '2017'
             GROUP BY RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2), Tracker, callsource) as A
INNER JOIN  (SELECT RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2) [week],
                    Tracker,
                    COUNT(callid) as Tickets
             FROM   calllog
             WHERE DATEPART(year,recvddate) >= '2017'
             GROUP BY RIGHT('00' + RTRIM(DATEPART(ww, recvddate)),2), Tracker) as B ON A.[week] = B.[week]
                                                                                    AND A.Tracker B.Tracker
ORDER BY [Week], Tracker
