Problem in custom column

Hi! I 'm trying to create a custom question in which I was able to do the cumulative sum of other two columns. Now I want to add a custom column where I’ll calculate the percentages of these cumulative values, the problem is, when I click to view my results, I see the following error:

No method in multimethod ‘->honeysql’ for dispatch value: [:mysql :cum-sum]

I noticed that there’s an open issue about that (https://github.com/metabase/metabase/issues/13634) but I wanted to check if someone has found a way to solve/contour this problem. Thank you.

Hi @Larissa
You would have to manually code the cumulative sum in SQL as a workaround.
