Counting the number of objects that have passed a threshold per day?

Salutations Qliksters!

 

I have a measure: sum(a)/sum(b)

 

I want to count how many objects, per day and in a table, have crossed a defined threshold.

I can get what I want with an if statement, but it is slow. Is there any way to write a set analysis expression to do this?

 

sum(aggr(if((sum(a) / sum(b)) < 1000, 1, 0),OBJECT, timestampDate))

Can you create an aggregate table in your data model:

 

aggr_object_date:

  load

    timestampDate

  ,OBJECT

  ,if((sum(a) / sum(b)) < 1000, 1, 0) as ThresholdFlag_Date_Object

resident <table>

group by 

    timestampDate

  ,OBJECT

;

 

create and join by composite key (timeStampDate & '-' & timestampDate)

 

or if you only need by date...

aggr_date:

  timestampDate

  ,sum(MeasureFlag) as ThresholdFlag_Date

resident aggr_object_date

  group by timestampDate

;

 

drop table aggr_object_date;

 

and front-end would just be: sum(ThresholdFlag_Date)
