Previous rows value based on date (Nested Window Function from Azure DatbricksSQL in Power BI logic)

Hi,

How to achieve the values from previous row in Power BI (which means nested window functionality in Azure databricks).

I can exectre the query and display the results in Azure databricks. I would like to create a line chart in powerbi cloud using

Y axis as "Running_Total" and X axis as "Date_Value" values.

 

Query:(Azure databricks query)

SELECT to_date(servertime, 'yyyy-MM-dd') AS Date_Value,
count(*) AS Event_Count,
sum(count(*)) OVER (ORDER BY to_date(servertime, 'yyyy-MM-dd') ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Running_Total
FROM traces_p.data
INNER JOIN traces_p.type ON data.type = type.id
WHERE typename IN ('bookmark', 'app')
GROUP BY to_date(servertime, 'yyyy-MM-dd')
ORDER BY 1;

 

Result:

Date_Value     Events_Count      Running_Total
2023-07-17       1209                  1209
2023-07-18       1454                  2663
2023-07-19       1416                  4079
2023-07-20       1284                  5363
2023-07-21       1420                  6783
2023-07-22         48                    6831
2023-07-23        103                   6934

2023-07-24        2093                 9027

Created a mew measure for the colum and used the Fn like below. Its working,

RunningTotal = CALCULATE (
    SUM ( [EventsCount] ),    
        ALL ( data_customized ),
        data_customized[servertime] <= EARLIER (data_customized[servertime]))
Thank you.

Hi,

Below code works for my problem and displays the Running total properly.

As solution,

 

RunningTotal = CALCULATE (
    SUM ( [EventsCount] ),    
        ALL ( data_customized ),
        data_customized[servertime] <= EARLIER (data_customized[servertime]))

There are many ways to achieve running total. Assuming you aready have a measure called eventCount in your model.

Calculate([EventCount], Filter(Allselected(TableName) , Table[Date_value] <=Max(Table[Date_Value]) ))

Thank you.

 

Hi 
You are creating a caculated column, I gave an example syntax for measure. 
Also, while writing the measure I assumed that you have a measure called EventsCount 
if that is not the case then please create the measure first.

Hi Tharun,

I am getting the below error in the Table view itself.Attached screen shorts.

Its says cannot found or may be not used in the expression is thrown.

 

Thanks in advance.

HI,

Tharun Thank you for your reply and time. I am a new bee to the topic.

yes its a calculated column.

For new colum i have used like below,

= Table.AddColumn(#"Renamed Columns", "RunningTotal", each CALCULATE([EventsCount], Filter(Allselected(data_customized) , Table[servertime] <=Max(Table[servertime]) )))
