How do you combine data.length for different models in a tab?

edited June 25, 2020 in Questions
I have a tab that has three tables with all of the same object (Cases), but different models to separate them. How do I get a total of all cases to show in the tab to let the user know there are records present? I know how to get the count for one model, but I can't figure out how to get the sum.

    Short of using javascript, I'd create another model just for this purpose. That model have three conditions that with the following logic. 1 OR 2 OR 3
    Each condition would be Id "in" field model of another model field Id.

    Thanks for that answer. The conditions have changed on my end, though.

    Is it possible to get an aggregate count of records from three different objects?

    No,  it is not possible to aggregate data from multiple sObjects.

    Digging for another answer and I see this question.  Things have changed!

    Make a UI only field that aggregates the length of each model together.  Something like this. 


    That should get you your aggregated value to put in a tab...
