Hello Experts,
I'm struggling with missing hours in Datetime column.
My requirement:
1. Display hourly performance for each device in matrix format. (My table (oracle) doesn't have the performance for some hours. For eaxmple: 1/8/2023 1:00 AM, 1/8/2023 4:00 AM, 1/8/2023 2:00 PM, 1/8/2023 7:00 PM are missing in table because the device powered off for some performance issues. So these hours are not pulled in table. I need to fill them with desired value )
So, I tried to create a calendar table (start and end date from existing table) and tried joins (full outer/ inner join with calendar), but couldn't get the missing hour rows. Using calendar datetime as column in matrix, I was able to show 24 hours and all selected date range in table with blanks for non existing hours. But don't know how to fill the blank ones because they don't exist in table.
2. Display overall average performance of each device over date range selected.
Device performance is calculated with 4 different KPI metrics (A1, A2, A3, A4) I need to calculate average performance. But if the value doesn't exist for misisng hour, it should write the following: (A1 = 0; A2 = 0, A3 = 100, A4 = 1). Only then i'll be able to get correct averages for all selected datetime.
I tried several ways to pull the missing hours rows in table (as null - so I can fill something). I could get nowhere with this. Any suggestions would be much appreciated.
Thanks
Abhig
