【中文标题】SQL Server - 如何根据将插入数据半小时的表中的几个参数来计算持续时间？【英文标题】：SQL Server - How to sum duration based on few parameters from a table that will insert data for half an hour? 【发布时间】：2018-08-21 11:19:21 【问题描述】：为标题道歉，因为它可能与实际问题不同
我们正在为联络中心工作，我们的 SQL Server 表将捕获代理的休息时间、登录和注销的详细信息以及时间、持续时间和原因。
当代理去吃午餐 @2PM 并将其状态更改为 Break @2:10Pm 时，DB 将更新为午餐持续时间 600 秒。 IE。更改代理屏幕中的状态后，DB 将插入结束时间和因特定中断原因而发生的持续时间。
如果事件（中断）持续超过 30 分钟，则此表将每 30 分钟放置一个条目，直到代理更改其当前状态示例如下，
表格原始数据：
Agent Name SkilltargetID Event Date Time ReasonText Duration
Sathiya 5000 3 20-08-2018 10:00 BioBreak 180 Seconds
Sathiya 5000 3 20-08-2018 10:30 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:00 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:30 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:42 BioBreak 720 Seconds
Sathiya 5000 3 20-08-2018 12:01 Lunch 1140 Seconds
Sathiya 5000 3 20-08-2018 12:30 Lunch 1740 Seconds
Sathiya 5000 3 20-08-2018 12:32 Lunch 120 Seconds
Sathiya 5000 3 20-08-2018 01:00 Bio Break 1680 Seconds
Sathiya 5000 3 20-08-2018 01:29 Bio Break 1740 Seconds
我们有一个报告将显示日期、代理名称、开始时间、结束时间、ReasonText（中断原因）和持续时间。
预期输出：
Date Agent Name SkillTargetID Event Start Time End Time Reason Duration
20-08-2018 Sathiya 5000 3 9:57 AM 11:42 AM Bio Break 6300
20-08-2018 Sathiya 5000 3 12:01 AM 12:32 AM Lunch 3000
20-08-2018 Sathiya 5000 3 12:32 AM 1:29 PM Bio Break 3420
实际输出：
Date Agent Name SkillTargetID Event Start Time End Time Reason Duration
20-08-2018 Sathiya 5000 3 9:57 AM 10:00 AM Bio Break 180
20-08-2018 Sathiya 5000 3 10:00 AM 11:30 AM Bio Break 5400
20-08-2018 Sathiya 5000 3 11:30 AM 11:42 AM Bio Break 720
20-08-2018 Sathiya 5000 3 11:42 AM 12:01 AM Lunch 1140
20-08-2018 Sathiya 5000 3 12:01 AM 12:30 AM Lunch 1740
20-08-2018 Sathiya 5000 3 12:30 AM 12:32 AM Lunch 120
20-08-2018 Sathiya 5000 3 12:32 AM 1:00 AM Bio Break 1680
20-08-2018 Sathiya 5000 3 1:00 AM 1:29 AM Bio Break 1740

查询逻辑：
我们通过考虑行号和序列号来显示 TABLEA 表中的事件开始时间和结束时间，
RowNum = ROW_NUMBER() OVER (PARTITION BY SkillTargetID ORDER BY DateTime, SkillTargetID),
SerialNum = ROW_NUMBER() OVER (PARTITION BY SkillTargetID, Event,Duration ORDER BY DateTime),
来自 TABLEA。
获取 RowNum 和 SerialNum 后，我们将根据这些 RowNum 和 SerialNum 值选择一个名为 Activity 的字段，
[Activity] = CASE WHEN (CTE.Event = 3 AND CTE.Duration=1800 and CTE.SerialNum=1) THEN CTE.DateTime
WHEN (CTE.Event = 3 AND CTE.Duration=900 and CTE.SerialNum=1) THEN CTE.DateTime
WHEN (CTE.Event = 3 AND CTE.Duration=1800 and CTE.SerialNum<>1) THEN prev.DateTime
WHEN (CTE.Event = 3 AND CTE.Duration=900 and CTE.SerialNum<>1) THEN prev.DateTime
ELSE CTE.DateTime
END
FROM CTE
LEFT JOIN CTE prev ON prev.RowNum = (CTE.RowNum-CTE.SerialNum)+1 AND prev.SkillTargetID=CTE.SkillTargetID
开始时间和结束时间值基于上述[活动]。但它显示的数据不正确。
出现此问题的原因：
如果 SerialNum 基于 SkillTargetID、Event、Duration，它会为同一条目显示不同的值，并按预期为不同的条目显示 1，因此，如果我们有以下情况，我们会得到不正确的开始时间和结束时间，并且在报告。
Agent Name SkillTargetID Event Date Time ReasonText Duration
Sathiya 5000 3 20-08-2018 10:00 BioBreak 150 Seconds
Sathiya 5000 3 20-08-2018 10:30 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:00 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:30 BioBreak 1800 Seconds
Sathiya 5000 3 20-08-2018 11:42 BioBreak 720 Seconds
SerialNum 值将为第一条记录和最后一条记录显示 1，因为此查询认为它们是不同的事件并且不相同，但实际上都是相同的继续事件，应该在报告中的单行中显示。
【问题讨论】：
我建议同时格式化数据和 SQL，以便于阅读。现在您的数据没有在标题下对齐，并且由于缩进，SQL 的某些部分真的很难阅读。在 SQL Fiddle 或类似文件中提供数据也可能有助于获得答案。 @JamesZ 感谢您的评论。让我按照你说的格式化和对齐问题.. 还没有人回答，这意味着任何人都不清楚您的要求。显示。您的实际表格、预期输出并解释预期输出背后的逻辑，请一次只问一个问题。 【参考方案1】：据我了解，如果输出不正常，请重新解释要求。
