How use subquery in `in`?
I try create query with in (subquery)
sub = from(
d in Deffered,
select: d."ИД Категории",
distinct: true,
where:
d.date_change >= ^date and d.deleted != true
and fragment("md5(Исполнитель) = ?", ^hash)
)
from(
a in Answered,
select: {count(a."Номер")},
where: a.answer_date >= ^date
and a.deleted != true
and fragment("md5(Исполнитель) = ?", ^hash)
and a."ИД Категории" not in ^sub
)|>Repo.all()
throw error:
value
#Ecto.Query<from d in Dobrobot.Deffered, where: d.date_changein
= ^"2018-11-19 00:00:00" and d.deleted != true and fragment("md5(Исполнитель) = ?", ^"6634F0A9A3C5EB7D97FBA08C1F08A45D"),

As stated in Ecto.Query.API.in/2 documentation:
The right side may either be a list, a literal list or even a column in the database with array type.
That said, the right side of in clause cannot be a query. The easiest solution would be to first get the actual list from sub with Repo.all(sub) and use this list. This leads to 1 extra query and IMHO is fairly acceptable.
Another solution would be to use fragment if the DB behind allows in with a SELECT statement.
This reference might also shed a light.
