Tableau：时差不包括周末、非工作时间和节假日
Tableau: time difference excluding weekends, outside business hours, and holidays
我在 Tableau 工作。我有两个时间戳，想找出它们之间的 DD:HH:MM:SS 差异，不包括周末、非工作时间、 和假期 。我找到了许多解决周末和非工作时间的解决方案，但到目前为止还没有解决假期问题。这可能吗？如果不是，我是否需要使用某种假期查找 table 在我的自定义 SQL 中进行计算？
是的，您需要这样的东西：
- 每年一个假期table
- 营业时间table或硬编码
- 你需要担心任一端在假期或其他 un-times 内，并在减去它们之间的所有 un-times 之前将参数向内调整为 actual-time。
- 您还需要注意或适应差值是否为负（时间顺序错误）。
- 接下来担心开始和结束之间的 DST 差异，也许是另一种算法，或者，如果您的纪元包括 DST 法律更改，table。
我自己的问题有了答案。它确实需要使用假期 table 或定义假期的某种日历 table。这可能是 Excel、SQL，随便什么。您可能需要修改下面的加入条件以适应您的 table.
的具体情况
我使用的示例自定义 SQL 查询。 DESCRIPTION 指节日名称（“圣诞节”、“平安夜”等）
custom_sql1:
SELECT DISTINCT CALENDAR_YEAR,
DESCRIPTION AS DESCRIPTION_ASSIGNED,
HOLIDAY_DATE AS HOLIDAY_DATE_ASSIGNED
FROM YOUR_HOLIDAY_TABLE
custom_sql2:
SELECT DISTINCT CALENDAR_YEAR,
DESCRIPTION AS DESCRIPTION_CREATED,
HOLIDAY_DATE AS HOLIDAY_DATE_CREATED
FROM YOUR_HOLIDAY_TABLE
一旦有了，就可以开始了。
此示例有两个日期：创建个案的时间 (created_ts) 和分配个案的时间 (assigned_ts)。
(1) TABLE 加入
向左加入 holiday/calendar table 两次到主 table，每个时间戳一次。在下面的示例中 custom_sql_query 是我的主要 table，而 custom_sql_query1 和 custom_sql_query2 是我的假期 tables.
custom_sql_query1:
主要 TABLE 的自定义加入条件：
注意：这假设您的工作日结束时间是 8:00pm (20:00)。相应地调整“19”。
IF DATENAME('weekday',[assigned_ts]) = 'Friday'
AND DATEPART('hour',[assigned_ts]) > 19
THEN DATETRUNC('day',DATEADD('day',3,[assigned_ts]))
ELSEIF DATENAME('weekday',[assigned_ts]) = 'Saturday'
THEN DATETRUNC('day',DATEADD('day',2,[assigned_ts]))
ELSEIF DATENAME('weekday',[assigned_ts]) = 'Sunday'
THEN DATETRUNC('day',DATEADD('day',1,[assigned_ts]))
ELSEIF DATEPART('hour',[assigned_ts]) > 19
THEN DATETRUNC('day',DATEADD('day',1,[assigned_ts]))
ELSE DATETRUNC('day',[assigned_ts])
END
假期的自定义加入条件 TABLE：DATETRUNC('day',[HOLIDAY_DATE_ASSIGNED])
custom_sql_query2:
主要 TABLE 的自定义加入条件：
注意：这假设您的工作日结束时间是 8:00pm (20:00)。相应地调整“19”。
IF DATENAME('weekday',[created_ts]) = 'Friday'
AND DATEPART('hour',[created_ts]) > 19
THEN DATETRUNC('day',DATEADD('day',3,[created_ts]))
ELSEIF DATENAME('weekday',[created_ts]) = 'Saturday'
THEN DATETRUNC('day',DATEADD('day',2,[created_ts]))
ELSEIF DATENAME('weekday',[created_ts]) = 'Sunday'
THEN DATETRUNC('day',DATEADD('day',1,[created_ts]))
ELSEIF DATEPART('hour',[created_ts]) > 19
THEN DATETRUNC('day',DATEADD('day',1,[created_ts]))
ELSE DATETRUNC('day',[created_ts])
END
假期的自定义加入条件 TABLE：DATETRUNC('day',[HOLIDAY_DATE_CREATED])
(2) 创建参数
创建定义工作日开始和结束日期和分钟的参数。 Day Open Hour 和 Day Open Minute 参数示例如下。 Day Close Hour 和 Day Close Minute 将以完全相同的方式创建，除了您将“当前值”选项更改为与您的工作日结束 hour/minute 相对应的任何值：
[Day Open Hour]
Name: Day Open Hour
Data Type: Integer
Current Value: 8 (assumes workday starts at 8:00am)
Display format: Automatic
Allowable Values: Range
Range of values: Min = 0, Max = 23, Step = 1
[Day Open Minute]
Name: Day Open Minute
Data type: String
Current value: 00
Allowable values: List
List of values:
Value - Display As
0 00
30 30
(change minute increments as needed)
(3) 推迟您的时间戳：第二天
创建计算字段
如果某事 assigned/created 在营业时间之外，则轮到第二天的营业时间。请注意，我们尚未排除周末或节假日。
assigned_ts: next day:
IF (DATEPART('hour', [assigned_ts]) * 60) + DATEPART('minute', [assigned_ts])
> (60 * ([Day Close Hour]) ) + INT([Day Close Minute])
THEN
// created after End of Day so round to start of next business day
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute]),
DATETRUNC('day',[assigned_ts]))
ELSEIF
(DATEPART('hour', [assigned_ts]) * 60) + DATEPART('minute', [assigned_ts])
< (60 * [Day Open Hour]) + INT([Day Open Minute])
THEN
// created before Start of Day so round to start of business day
DATEADD('minute', (60 * [Day Open Hour]) + INT([Day Open Minute])
, DATETRUNC('day',[assigned_ts]))
ELSE
[assigned_ts]
END
created_ts: next day:
IF (DATEPART('hour', [created_ts]) * 60) + DATEPART('minute', [created_ts])
> (60 * ([Day Close Hour]) ) + INT([Day Close Minute])
THEN
// created after End of Day so round to start of next business day
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute]),
DATETRUNC('day',[created_ts]))
ELSEIF
(DATEPART('hour', [created_ts]) * 60) + DATEPART('minute', [created_ts])
< (60 * [Day Open Hour]) + INT([Day Open Minute])
THEN
// created before Start of Day so round to start of business day
DATEADD('minute', (60 * [Day Open Hour]) + INT([Day Open Minute]), DATETRUNC('day',[created_ts]))
ELSE
[created_ts]
END
(4) 推动您的时间戳：不包括周末
如果您上面的“四舍五入”时间戳落在周末，这会将它们推到下周一。再创建两个计算字段：
assigned_ts: next weekday:
IF DATENAME('weekday',[assigned_ts: next day]) = "Saturday"
THEN
// move to start of day Monday by adding two days (48 hrs) and the Monday morning hours
DATEADD('minute', (60 * (48 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next day]))
ELSEIF DATENAME('weekday',[assigned_ts: next day]) = "Sunday"
THEN
// move to start of day Monday by adding a day (24 hrs) and the Monday morning hours
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next day]))
ELSE
[assigned_ts: next day]
END
created_ts: next weekday:
IF DATENAME('weekday',[created_ts: next day]) = "Saturday"
THEN
// move to start of day Monday by adding two days (48 hrs) and the Monday morning hours
DATEADD('minute', (60 * (48 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next day]))
ELSEIF DATENAME('weekday',[created_ts: next day]) = "Sunday"
THEN
// move to start of day Monday by adding a day (24 hrs) and the Monday morning hours
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next day]))
ELSE
[created_ts: next day]
END
(5) 推动您的时间戳：排除假期
如果时间戳不在工作时间，您首先将时间戳推到第二天。然后，如果它在第一次推送后的周末下跌，则将其进一步推送到星期一。现在，如果遇到假期，你会第三次推送它。请注意，我们将周五的假期计算在内。再创建两个计算字段。
这些计算中的第一个条件假设您在感恩节后一天休假。
assigned_final:
IF ([DESCRIPTION_ASSIGNED] = 'Thanksgiving Day'
OR [DESCRIPTION_ASSIGNED]= 'Christmas Eve')
AND DATENAME('weekday',[assigned_ts: next weekday]) = "Thursday"
THEN
// move to start of day Monday by adding 4 days (96 hrs) and the Monday morning hours
DATEADD('minute', (60 * (96 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next weekday]))
ELSEIF NOT ISNULL([HOLIDAY_DATE_ASSIGNED])
AND DATENAME('weekday',[assigned_ts: next weekday]) = "Friday"
THEN
// move to start of day Monday by adding 3 days (72 hrs) and the Monday morning hours
DATEADD('minute', (60 * (72 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next weekday]))
ELSEIF [DESCRIPTION_ASSIGNED]= 'Christmas Eve'
THEN
// move to start of next day by adding 2 days (48 hrs) and the morning hours
DATEADD('minute', (60 * (48 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next weekday]))
ELSEIF NOT ISNULL([HOLIDAY_DATE_ASSIGNED])
THEN
// move to start of next day by adding 1 day (24 hrs) and the morning hours
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [assigned_ts: next weekday]))
ELSE
[assigned_ts: next weekday]
END
created_final:
IF ([DESCRIPTION_CREATED] = 'Thanksgiving Day'
OR [DESCRIPTION_CREATED]= 'Christmas Eve')
AND DATENAME('weekday',[created_ts: next weekday]) = "Thursday"
THEN
// move to start of day Monday by adding 4 days (96 hrs) and the Monday morning hours
DATEADD('minute', (60 * (96 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next weekday]))
ELSEIF NOT ISNULL([HOLIDAY_DATE_CREATED])
AND DATENAME('weekday',[created_ts: next weekday]) = "Friday"
THEN
// move to start of day Monday by adding 3 days (72 hrs) and the Monday morning hours
DATEADD('minute', (60 * (72 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next weekday]))
ELSEIF [DESCRIPTION_CREATED]= 'Christmas Eve'
THEN
// move to start of next day by adding 2 days (48 hrs) and the morning hours
DATEADD('minute', (60 * (48 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next weekday]))
ELSEIF NOT ISNULL([HOLIDAY_DATE_CREATED])
THEN
// move to start of next day by adding 1 day (24 hrs) and the morning hours
DATEADD('minute', (60 * (24 + [Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day', [created_ts: next weekday]))
ELSE
[created_ts: next weekday]
END
(6) 中间计算
- 计算每个工作日的分钟数。
minutes per workday:
(60 * ([Day Close Hour] - [Day Open Hour]) + INT([Day Close Minute]) - INT([Day Open Minute]))
- 查找一天开始与修改后的分配时间戳之间的分钟数
assigned_final: time to SOD:
DATEDIFF( 'minute',
DATEADD('minute', (60 * ([Day Open Hour])) + INT([Day Open Minute])
, DATETRUNC('day',[assigned_final])),
[assigned_final]
)
- 查找修改后的创建时间戳与工作日结束之间的分钟数
created_final: time to EOD:
DATEDIFF( 'minute',
[created_final],
DATEADD('minute', (60 * ([Day Close Hour])) + INT([Day Close Minute])
, DATETRUNC('day',[created_final]))
)
(7) 时差
以分钟为单位计算时差。
Time to Assign:
IF DATETRUNC('day', [created_final]) =
DATETRUNC('day', [assigned_final])
THEN
// the same day so just return the minutes between the two times on the same day
[DateDiff minutes]
ELSEIF DATETRUNC('week', [created_final]) =
DATETRUNC('week', [assigned_final])
THEN
// the two days are in the same week, so add the time on the created day,
// the time on the end day, plus a full day for each day between
(([DateDiff days] - 1) * [minutes per workday] ) +
[created_final: time to EOD] + [assigned_final: time from SOD]
ELSE
// the days are in two different weeks, so get the same calc as above,
// and subtract the weekends between.
// weekends between would be datediff weeks * 2 * work minutes per day
(([DateDiff days] - 1 - ([DateDiff weeks] * 2)) * [minutes per workday] ) +
[created_final: time to EOD] + [assigned_final: time from SOD]
END
