How to create a TimeKey from a time column in hh:mm:ss format.

[Anonymous]

Hi team

How can i create a TimeKey column from a Time column in powerquery.

The timekey column will be in seconds from 1-86400. 
This is similar to creating a datakey eg: 2019-06-13 to 20190613. 

The idea behind creating a timekey is to join this fact table key to a timekey in a time dimension table in my dw which would allow for the data to be sliced by different time fields.

i would prefer to do this in Power Query.

Hi @Anonymous ,

Enter the Query Editor, click on your query, go to tab "Add Column" -> "Custom Column", enter column name and formula like code below, adjust the code by adding ", type time". Don't forget to click the "Close & Apply" button.

=#time(0,0,0) + #duration(0,0,0,[TimeKey])

Hi @v-xicai , Unfortuantely thats not what i am after as i already have a time column! 

I am trying to convert time from hh:mm:ss to seconds (wholenumber). This would then form a key to be joined to a time dimension table.

Time.Hour([Time])*60*60+Time.Minute([Time])*60+Time.Second([Time])
