Hey, I noticed one thing just now. We can actually use subqueries in from
clause at least for JdbcDataContext. Below is the query I ran which was
successful.
Query query = dataContext.parse("SELECT password as X from (select
username,password from AMASS_USER) S");
> Ordering on aggregation value not working

> URL: https://issues.apache.org/jira/browse/METAMODEL-128
> Project: Apache MetaModel
> Issue Type: Bug
> Affects Versions: 4.3.2
> Reporter: Ashish Mukherjee
>
> I am using a CSV Data Context example with multiple fields - occurrences,
> first_name, last_name.
> The query -
> SELECT SUM(persons.csv.occurrences) AS X, persons.csv.first_name FROM
> ashish.persons.csv GROUP BY persons.csv.first_name ORDER BY X
> This query always orders the results by first_name and not the aggregation
> value.
