mysql - 针对单个条件按多列分组

Question

我在下面有一个查询正在运行，但不是我想要的那样。

查询为我们的 CSR 提取电话数据，我们目前正在获取 15 个代理的数据。当前查询获取我需要的总计，但将它们全部加起来并给出一行总计。我想让它显示每个 CSR 的总数。问题在于源表中的每个调用记录都有其 4 位扩展名作为主叫号码或被叫号码。但是，每条记录中都没有一个字段可以将该用户的分机号与调用联系起来。它必须作为主叫号码或被叫号码存在。

所以我相信我的逻辑是正确的，只是现在我需要按分机对调用进行分组。因此对于 15 个 CSR，我希望语句返回 15 行，每行都有自己的总计。但由于没有通用字段可作为分组依据，我认为我需要按这两个字段进行分组。

换句话说，“如果 callingpartyno 有 7200 而 finallycalledpartyno 有 7200，将这些分组为分机 7200 的总数”。

下面是数据在源表中的外观示例:

    callingpartyno | finallycalledpartyno 
    -------------------------------------
    1234                outside   
    1234                outside   
    1234                outside   
    outsidecall         1234          
    outsidecall         1234          
    outsidecall         1234          
    9876                outside   
    9876                outside   
    9876                outside   
    outsidecall         9876         
    outsidecall         9876                  
    outsidecall         9876                  

如您所见，没有任何内容可以将每条记录标识为同一 CSR。

这里是查询:

 SELECT

        sum(Duration) AS total_talk_time_seconds
      , round(sum(Duration) / 60,2) AS total_talk_time_minutes
      , sum(if(LEGTYPE1 = 1,1,0)) AS total_outbound
      , sum(if(LEGTYPE1 = 2,1,0) and ANSWERED = 1) AS total_inbound
      , sum(if(LEGTYPE1 = 2,1,0) and ANSWERED = 0) AS total_missed
      , SUM(IF(LEGTYPE1 = 1, 1, 0)) +                   -- outbound calls
        SUM(IF(LEGTYPE1 = 2, 1, 0))  AS total_calls
      , NOW() AS time_of_report
      , curdate() AS date_of_report
FROM cdrdb.session a
    INNER JOIN cdrdb.callsummary b
      ON a.NOTABLECALLID = b.NOTABLECALLID
    where date(b.ts) = '2017-10-16 00:00:00'
    AND callingpartyno IN (7276,7314, 7295, 7306,7357,7200,7218,7247 7331,7255,7330,7000,7215, 7240,7358,7312) 
    OR  finallycalledpartyno IN (7276,7314, 7295, 7306,7357,7200,7218,7247 7331,7255,7330,7000,7215, 7240,7358,7312) 

再一次，查询可以提取指定日期的记录，其中任何扩展名都在 callingpartyno 或 finallycalledpartyno 中，但我需要一种方法将其按这两个分组并将每条记录视为 4 位扩展名，几乎就像一个用户 ID。

这正是 group by 子句的用途。通过插入 case 语句，我们可以使用您自己的条件创建一个 ID。

 select
  case 
    when callingpartyno       in (7276,7314,7295,7306,7357,7200,7218,7247,7331,7255,7330,7000,7215,7240,7358,7312)
      then callingpartyno
    when finallycalledpartyno in (7276,7314,7295,7306,7357,7200,7218,7247,7331,7255,7330,7000,7215,7240,7358,7312)
      then finallycalledpartyno
  end as id
  , sum(duration) as total_talk_time_seconds
  , round(sum(duration) / 60,2) as total_talk_time_minutes
  , sum(if(legtype1 = 1,1,0)) as total_outbound
  , sum(if(legtype1 = 2,1,0) and answered = 1) as total_inbound
  , sum(if(legtype1 = 2,1,0) and answered = 0) as total_missed
  , sum(if(legtype1 = 1, 1, 0)) +                   -- outbound calls
    sum(if(legtype1 = 2, 1, 0))  as total_calls
  , now() as time_of_report
  , curdate() as date_of_report
from 
  cdrdb.session a
  join cdrdb.callsummary b
    on a.notablecallid = b.notablecallid
where 
  date(b.ts) = '2017-10-16 00:00:00'
  and (
    callingpartyno           in (7276,7314,7295,7306,7357,7200,7218,7247,7331,7255,7330,7000,7215,7240,7358,7312)
    or  finallycalledpartyno in (7276,7314,7295,7306,7357,7200,7218,7247,7331,7255,7330,7000,7215,7240,7358,7312)
  )
group by
  id -- <-- the calculated field we created in the select clause

我还更正了您的 或 声明。像您一样在括号外使用它会使日期或多或少变得无关紧要。
