Question

我希望这只是我的格式错误，所以我不会发布更多我的查询而不是必要的。

我有一个包含多个连接和多个SUM参数的大型查询（此查询的目的是在每次运行时聚合每日总计）。

这是我的麻烦行：

sum(case when (duration > 60 and LEGTYPE1 = 1) then 1 else 0 end)

我也试过这个：

count(case when (duration > 60 and LEGTYPE1 = 1) then 1 else null end)

这是问题：总和案例返回1或0，计数行确实返回计数（13,14,16），但它不是我记录的正确数字。

以下是上下文的整个查询：

SELECT c.extension
      , 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(Answered = 1,0,1)) AS Total_Missed
      , SUM(IF(LEGTYPE1 = 1, 1, 0)) +                   -- outbound calls
        SUM(IF(LEGTYPE1 = 2, 1, 0) AND ANSWERED = 1) +  -- inbound calls
        SUM(IF(Answered = 1, 0, 1))  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
  INNER join cdrdb.mxuser c
       ON a.RESPONSIBLEUSEREXTENSIONID = c.EXTENSIONID
  WHERE b.ts >= curdate()
  AND c.extension IN (7276,7314,7295,7306,7357,7200,7218,7247,7331,7255,7330,7000,7215,7240,7358,7312)
  group by c.extension

因此，当我执行该行的计数版本时，该数字与调用的总数相匹配，其中它应仅表示持续时间超过60秒的出站数。数据是正确的，字段是正确的，我只是问我的语法是否正确，或者只是有一种更好的方法来构建它。

不确定我是否遵循您的逻辑，但是：

sum(if(LEGTYPE1 = 2,1,0) and ANSWERED = 1) AS Total_Inbound

和

SUM(IF(LEGTYPE1 = 2, 1, 0) AND ANSWERED = 1) +  
    SUM(IF(Answered = 1, 0, 1))  AS Total_Calls

似乎错了。尝试：

sum(if(LEGTYPE1 = 2 and ANSWERED = 1, 1, 0) AS Total_Inbound

和

SUM(IF(LEGTYPE1 = 2 AND ANSWERED =1 , 1, 0) +  
    IF(Answered = 1, 0, 1)
)  AS Total_Calls

计算/总和不按预期方式工作
