我有这个查询，它为传出调用的每个小时日期分组计数。有没有办法在同一个查询中同时获得传入的数量？

Answer 1

试试这个：

SELECT 
 Calldate
 from_unixtime(FLOOR(UNIX_TIMESTAMP(calldate)/(60*60))*(60*60)) GroupTime, 
 SUM(calltype='incoming') as CntIn, 
 SUM(calltype='outgoing') as CntOut 
FROM asterisk.cdr 
WHERE accountcode = '10102-131' 
  AND DATE (calldate) = DATE (NOW()) 
  AND calltype IN ('incoming', 'outgoing' )
GROUP BY GroupTime;

假设“传出”和“传入”是通话中的描述符：

SELECT date(calldate), hour(calldate) as callhour,
       count(*) as Cnt,
       sum(calltype = 'outgoing') as CntOut,
       sum(calltype = 'incoming') as CntIn
FROM asterisk.cdr 
WHERE accountcode = '10102-131' AND
      (calldate >= curdate() and calldate < date_sub(curdate(), interval 1 day)
      ) AND
      calltype IN ('outgoing' , 'incoming')
GROUP BY date(calldate), hour(calldate);

注意：

我发现hour（）函数更容易用来获取小时。但是，它返回一个整数而不是一个时间，所以它可能不是你真正想要的。
在date()上使用calldate可以阻止使用索引。所以，我用不等式替换了那个逻辑。
我假设你想要传出和来电的单独计数。

如果可以通过calltype分组，请尝试：

SELECT 
   calltype 
   , calldate
   , from_unixtime(FLOOR(UNIX_TIMESTAMP(calldate)/(60*60))*(60*60)) GroupTime
   ,case when calltype='outgoing' then COUNT(*) else 0 end as CntOut 
   ,case when calltype='ingoing' then COUNT(*) else 0 end as CntIn 
 FROM asterisk.cdr 
 WHERE 
   accountcode = '10102-131' 
   AND DATE (calldate) = DATE (NOW()) 
   AND (calltype = 'outgoing' or calltype='ingoing')--if calltype in only 'ingoing' or 'outgoing', you can omit this line
 GROUP BY calltype, calldate;

但如果没有，查询会有点复杂：

SELECT 
   t.calldate
   , from_unixtime(FLOOR(UNIX_TIMESTAMP(t.calldate)/(60*60))*(60*60)) GroupTime
   , t_out.cnt as CntOut
   , t_in.cnt as CntIn
 FROM 
  asterisk.cdr as t
  left join (select calldate,count(*) cnt from asterisk.cdr where calltype='outgoing' group by calldate) as t_out
  on t.calldate=t_out.calldate
  left join (select calldate,count(*) cnt from asterisk.cdr where calltype='ingoing' group by calldate) as t_in
  on t.calldate=t_in.calldate
 WHERE 
   t.accountcode = '10102-131' 
   AND DATE (t.calldate) = DATE (NOW()) 
 GROUP BY  t.calldate;

日期组中的MySQL多个计数
