我有一张桌子,如下。我想在power bi中有另一个表,该表可以在特定日期告诉我什么是Min(StartTime)和Max(endTime)。
LogTime Job_Name StartTime endTime
9/18/2018 Job1 9/18/2018 10:27 9/18/2018 10:28
9/18/2018 Job2 9/18/2018 9:47 9/18/2018 9:51
9/18/2018 Job3 9/18/2018 9:41 9/18/2018 9:50
9/18/2018 Job4 9/18/2018 9:46 9/18/2018 9:48
9/17/2018 Job5 9/17/2018 11:23 9/17/2018 11:25
9/17/2018 Job6 9/17/2018 11:17 9/17/2018 11:24
9/16/2018 Job7 9/16/2018 17:20 9/16/2018 17:23
9/16/2018 Job8 9/16/2018 17:18 9/16/2018 17:21
9/16/2018 Job9 9/16/2018 17:17 9/16/2018 17:21
9/14/2018 Job10 9/14/2018 17:19 9/14/2018 17:21
9/14/2018 Job11 9/14/2018 17:19 9/14/2018 17:20
9/14/2018 Job12 9/14/2018 17:17 9/14/2018 17:20
9/14/2018 Job13 9/14/2018 17:16 9/14/2018 17:20
必需表:
LogTime StartTime endTime endTime-StartTime
9/18/2018 9/18/2018 9:46 9/18/2018 10:28 hh:mm
9/17/2018 9/17/2018 11:17 9/17/2018 11:25
9/16/2018 9/16/2018 17:17 9/16/2018 17:23
9/14/2018 9/14/2018 17:16 9/14/2018 17:21
答案 0 :(得分:0)
您可以使用Power Query Editor来实现。我命名了起点(您的数据)baseTable,并将其用作targetTable(您的必需表)的源。
这些步骤是:
脚本如下:
let
Source = #"baseTable",
#"Grouped Rows" = Table.Group(Source, {"LogTime"}, {{"minTime", each _, type table}, {"maxTime", each _, type table}}),
#"Added Custom" = Table.AddColumn(#"Grouped Rows", "minStart", each Table.Min([minTime],"StartTime")),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "maxEnd", each Table.Max([maxTime],"endTime")),
#"Expanded minStart" = Table.ExpandRecordColumn(#"Added Custom1", "minStart", {"StartTime"}, {"StartTime"}),
#"Expanded maxEnd" = Table.ExpandRecordColumn(#"Expanded minStart", "maxEnd", {"endTime"}, {"endTime"}),
#"Added Custom2" = Table.AddColumn(#"Expanded maxEnd", "endTime-StartTime", each [endTime]-[StartTime]),
#"Changed Type" = Table.TransformColumnTypes(#"Added Custom2",{{"StartTime", type time}, {"endTime", type time}, {"endTime-StartTime", type duration}}),
#"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"minTime", "maxTime"})
in
#"Removed Columns"
将此脚本复制到“高级编辑器”时,使用空白查询新来源,您应该能够查看“应用步骤”。
