I talked about XQL not the query manager. I tough JPQL was part of JCR.

XWQL is not tied to JCR (the execution engine is Hibernate right now). It's tied to
JPQA but only at the grammar level (we have our grammer and our parser). Hi devs,
I'm wondering why we haven't moved to using XQL instead of HQL.
Any reason?
If not, I'd like to suggest we start using it everywhere we currently use HQL since
XWQL since is much nicer. Also since we don't use it our users don't use it.
Additionally I'd like to propose that we move to a ScriptService to access the query
manager.
From Velocity you'd write the following to get a Query:
$services.query.xwql("....")
Note that the ScriptService implementation would replace the SecureQueryManager
implementation.
We would also deprecate XWiki.getQueryManager.
WDYT?
I think the major issue is that nobody knows it very well and without
Artem to push on it and help we just forgot about it.
Also I think Artem was waiting JCR2 that was not release when he
started working on it to finish XQL implementation that was too
limited by JCR1.
Why do you think it's not finished? from what I've seen it looks finished and it
worked well when I used it.
I said "i think".
I only saw a potential grammar issue that you are forces to use "as" for a
query to be valid. For example:
"from doc.object(XWiki.XWikiUsers) as user"
(using "from doc.object(XWiki.XWikiUsers)" will not work)

But yes we should really use XQL if possible.
