Mike,
Would this select query be able to get our aggregated data?
query = select(func.max(DataModel.value)).select_from(_query
.subquery()).group_by(
func.date_format(DataModel.timestamp, "%Y-%m-%d %H")
)
We tried this route but are now getting this error
"errors":
Thanks Mike,
Ideally we'd prefer to find a solution via Graphene-SQLAlchemy.
Unfortunately we don't have the luxury of creating our own query when
interacting with Graphene-SQLAlchemy.
So the key question for us is, can you modify an existing
sqlalchemy.orm.query.Query object to insert a "func

Are there performance difference between the following line of codes.

I am a bit confused by the behavior for the methods all() and one() if
the Query would return an empty result set. In the case of all() it
returns an empty list whereas one() will throw an exception
(sqlalchemy.exceptions.InvalidRequestError). I am sure there was a
reason to implement as it is now
