我需要 return 基于日期的连续数据集中重复值的最大计数
I need to return the Max count of repeating values in a consecutive data set based on dates
这是我的 table 的示例：
MID RecordDate Volume
5555 4/1/2017 1
5555 4/2/2017 2
5555 4/3/2017 2
5555 4/4/2017 2
5555 4/5/2017 3
5555 4/6/2017 3
5555 4/7/2017 3
5555 4/8/2017 3
5555 4/9/2017 3
5555 4/10/2017 3
5555 4/11/2017 3
5555 4/12/2017 3
5555 4/13/2017 3
5555 4/14/2017 3
5555 4/15/2017 3
5555 4/16/2017 3
5555 4/17/2017 3
5555 4/18/2017 3
5555 4/19/2017 3
5555 4/20/2017 3
5555 4/21/2017 3
5555 4/22/2017 3
5555 4/23/2017 3
5555 4/24/2017 3
5555 4/25/2017 3
5555 4/26/2017 2
5555 4/27/2017 2
5555 4/28/2017 2
5555 4/29/2017 2
5555 4/30/2017 2
我正在尝试 return 在定义的时间段内具有相同交易量的连续天数。在我的示例中，数据是从 2017 年 4 月 1 日到 2017 年 4 月 30 日，但实际上想将其调整为 30/40/60/90 天的任何日期范围..
我的预期结果与此类似：
+------+-------------+------------+---------+--------+
| MID | Start Date | End Date | Volume | Count |
+------+-------------+------------+---------+--------+
| 5555 | 4/5/2017 | 4/25/2017 | 3 | 21 |
+------+-------------+------------+---------+--------+

所以这是该示例的解决方案代码，其他人可以帮助我为具有多个 MID 的 table 工作吗，我需要为每个 MID 提取最大的插值计数:

, EndDate = convert(char(10),max(md1.RecordDate),120)

, cnt = count(*)
From (
Select md.MerrickID

group by md1.merrickid, md1.EstGasVolMCF, grp
