I am trying to create a query to populate an attribute

the “Name” (an attribute of another object) .
I seem to have run into an issue, in which I created a special space
(CustomClass) to house all my User defined classes.
I can’t seem to build a query to access that space.
I have tried to normal default query that I found which worked was:
select doc.fullName from XWikiDocument doc
this of course returns all the documents in the wiki.
Is there a way that I can get all the pages listed in a specific space and
not just the XWiki default space (I assume I should be able to do this),
#set($hql = "where doc.space='YourSpace')
and
if I can do this, how can I query an instance of a class (Foo) that lives in
the CustomClass
Do you mean querying instances of a class instantiate in a given
document? I think many examples in...
http://platform.xwiki.org/xwiki/bin/view/DevGuide/velocityHqlExamples
... apply to your situation. If you want to get all objects of a given
class:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/velocityHqlExamples#HGett…
If you want to query properties on that objects:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/velocityHqlExamples#HGett…
I can't help with the update part of your question. But I think I would
be better if you get the select clause working first!
I have tried and several permutations of the following
query. I am hitting
my head against a wall and all help would be greatly appreciated. Things
that have been unsucessfull, Xwiki.CustomClass.Foo, Foo itself, the modifier
seen below, I am at a loss on how to currently approach this.
select foo.Name from CustomClass.Foo foo
I am new to HQL, and while I have read up, it has not quite yet solved my
problem in dealing with this XWiki problem. It is important to note that I
have also taken the query out and used the feiled for Class, and Value but
that also did not work. Advice?
Thank you

HTH. If it doesn't, don't hesitate to be more specific and I'll try
to
help! I'm learning HQL myself! :-)
