Select Merge with Map of Max field
Hi, I want to display some fields and only when value when there exists multiple. Currently, I have:
|> select_merge([m, md], map(m, ^[:a, :b, :c]))
And I want to have the max() for each field so it doesn’t show multiple values when they are a little different (same id).
I think I will probably need to extend the Query.API to do something like this, I was looking if there was some alternative to do this with the available functions.

I’m not entirely sure I understand what you’re asking for. Can you perhaps sketch the SQL that you’d use and then we can suggest how you’d achieve that with the query DSL?
