我需要在0到10秒，0到20秒等特定范围内对呼叫进行计数。计数将增加，而增量将是当前和下一个之间的不同计数。 ％将是当前计数/最终计数总数。
以下是可以与数据一起使用的sqlfiddle：http://sqlfiddle.com/#!9/803d2/2
callsdetails示例表：
+-----+----------------+----------+----------+---------------+
| id | callid | callerno | duration | status |
+-----+----------------+----------+----------+---------------+
| 634 | 1479097551.228 | 1000 | 2 | complete |
| 635 | 1479102518.248 | 1000 | 12 | complete |
+-----+----------------+----------+----------+---------------+
预期结果：
+------------------------+----------+----------+----------+
| Ranges | Count | Delta | % |
+------------------------+----------+----------+----------+
| Between 0 to 10 secs | 44 | +44 | 84.62 % |
| Between 0 to 20 secs | 48 | +4 | 92.31 % |
| Between 0 to 30 secs | 50 | +2 | 96.15 % |
| Between 0 to 40 secs | 51 | +1 | 98.08 % |
| Between 0 to 50 secs | 51 | +0 | 98.08 % |
| Between 0 to 60 secs | 51 | +0 | 98.08 % |
| Between 0 to 70 secs | 51 | +0 | 98.08 % |
| Between 0 to 80 secs | 52 | +1 | 100.00 % |
| Between 0 to 90 secs | 52 | +0 | 100.00 % |
| Between 0 to 100+ secs | 52 | +0 | 100.00 % |
+------------------------+----------+----------+----------+
Total 52
我现在能够创建的是查询以下，如果您可以帮助提供更好的解决方案，请咨询。我现在面临的问题是（优先级）我无法得到计数和（次要）％的最终计数总数（52），现在我手动输入最终计数总数（52）。请帮忙。
SELECT Ranges,Delta,ROUND(Delta/52*100,2) AS '%'
FROM
(
SELECT
(
IF(duration<=10,'10',IF(duration<=20,'20',IF(duration<=30,'30',
IF(duration<=40,'40',IF(duration<=50,'50',
IF(duration<=60,'60',IF(duration<=70,'70',IF(duration<=80,
'80',IF(duration<=90,'90','100+'))))))))))
AS Ranges,COUNT(duration) AS Delta
FROM callsdetails
GROUP BY Ranges
) a
GROUP BY Ranges;
当前结果：
+--------+-------+-------+
| Ranges | Delta | % |
+--------+-------+-------+
| 10 | 44 | 84.62 |
| 20 | 4 | 7.69 |
| 30 | 2 | 3.85 |
| 40 | 1 | 1.92 |
| 80 | 1 | 1.92 |

=============================================== ============================
感谢Etsa帮助我解决了上述问题，即所有呼叫的总数，我现在可能需要再次提供帮助，并且每个队列名称都需要添加分组。它与上面的公式相同，但现在必须按队列名称拆分或分组。

答案 0 :(得分：0)
一种方法可能是这个（使用变量获取累积和，并使用所有间隔的JOIN。最后我添加了一个带有SELECT COUNT（*）的JOIN来获得52）：
SELECT RAN, TOT_COUNT, DELTA, ROUND(TOT_COUNT/E.TOT*100,2) AS '%'
FROM (SELECT B.RAN, a.Ranges, COALESCE(a.Delta,0) AS DELTA
, @r:=@r+COALESCE(a.Delta,0) AS TOT_COUNT
FROM (SELECT (
IF(duration<=10,'10',IF(duration<=20,'20',IF(duration<=30,'30',
IF(duration<=40,'40',IF(duration<=50,'50',
IF(duration<=60,'60',IF(duration<=70,'70',IF(duration<=80,
'80',IF(duration<=90,'90','100+'))))))))))
AS Ranges,COUNT(duration) AS Delta
FROM callsdetails C
GROUP BY Ranges) A
RIGHT JOIN (SELECT '10' AS RAN, 1 AS ORD UNION ALL SELECT '20', 2 AS ORD UNION ALL SELECT '30', 3
UNION ALL SELECT '40', 4 UNION ALL SELECT '50', 5 UNION ALL SELECT '60',6 UNION ALL SELECT '70',7
UNION ALL SELECT '80',8 UNION ALL SELECT '90',9 UNION ALL SELECT '100+',10) B ON A.Ranges=B.RAN
CROSS JOIN (SELECT @r:=0) T
ORDER BY ORD
) D
CROSS JOIN (SELECT COUNT(*) AS TOT FROM callsdetails) E
;
输出：
RAN TOT_COUNT DELTA %
10 44 44 84.62
20 48 4 92.31
30 50 2 96.15
40 51 1 98.08
50 51 0 98.08
60 51 0 98.08
70 51 0 98.08
80 52 1 100
90 52 0 100
100+ 52 0 100
