Calculate percent of whole
I have rows of client data with 2 fields `weeks` and `recommended_weeks`. I would simply like to know what percent of rows have `weeks` = `recommended_weeks`. For some reason I can't seem to make this work. I tried the following but it's showing me ALL rows, rather than an average.
sum(case when `weeks` = `recommended_weeks` then 1 else 0 end) / count(`id_client`)
It seems like it should be simple enough to separate the data into 2 populations (one where `weeks` = `recommended weeks` and one where `weeks` != `recommended_weeks` but for whatever reason, I cannot seem to get a single number out of the data.

@user060355 , it sounds simple, but i'm not sure i follow your data structure.
can you upload a sample?
what happens when you break your beast mode into separate parts (i.e. which part is breaking? the numerator or the denominator?)
