Interpolate Ecto.Enum in fragment/1

%{
        date: fragment("date_trunc(?,?) as date",
          type(^params.date_trunc_type, DateTruncType),
          l.inserted_at)
}

This worked! I tried type/2 before like this, but this didn’t work. Mb @LostKobrakai advice helped or i’ve used type/2 wrong.

@LostKobrakai, @joey_the_snake ty for help.
