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

How to use this query in power bi? Any DAX query ? or Formula can be used?
Thank in Advance.
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.

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,
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]))ThanksCreated 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.
