Could be solved if the following issue was solved:
https://hibernate.onjira.com/browse/HHH-16
(Explicit joins on unrelated classes)
But this issue has been there for a very long time ...
And even with that it would consider that non-matching items (objects
without average votes) would return null
As far as I can tell, you can only do joins in HQL *if* you have set up
object mappings (one-to-one, one-to-many, etc.). However, as far as I can
see in our Hibernate mapping, XWiki does not do these mappings and only
does basic property-to-primitiveType-to-table-column mappings.
This is also the
I had the exact same objective a long time ago and could not find a solution. I
think we thought about creating the missing objects.
I don't think coalesce would have worked. The main issue is get the lines

Hi Eduard,
Well, that's what I expected but I did not succeed to find a solution
with a unique query, wether in XWQL or HQL.
The solution would be to do a left join, but I could not find how to
formulate it and I wonder if it's possible with the current mappings.

Hi Jeremie,
If you ultimately resorted to HQL, I guess you could of used HQL all the
way instead of XWQL and have only 1 query instead of XWQL+HQL, right?
Thanks,
Eduard

Hi,
For the record, the only way I found to achieve my need was to execute
2 requests.
(the idea was to get list of pages ordered by ratings, then date).
First XWQL selects rated pages ordered by ratings then date:
#set($xwql = "select doc.fullName, ratings.averagevote from Document doc,
doc.obje
Hello community,
I'm stuck on a problem to query average ratings data from pages - I
installed the Ratings plugin, of course.
The following query works as expected, and shows the pages having average
votes, ordered by ratings then date :
#set($xwql = "select doc.fullName, ratings.averagevote fro
