It's not a scripting language, it's a query language. doc.object(Class) is supposed to be read as: search for documents that [meet some other conditions] and have an object of type "Class" You don't actually get the object as you would in a scripting environment. That part of the query will get translated into some SQL FROM and WHERE fragments, like all the other parts of the XWQL query. Remember, you're writing a *query*, not a script. > I want to know what APIs XWQL has access to, but I couldn't find the > information. > On Mon, Nov 12, 2012 at 11:42 PM, Jeremie BOUSQUET < > [email protected]> wrote: > >> doc.getObjects("MyClass") is from the xwiki core java api, but is not part >> of the XWQL querying language. >> >> The query: >> >> select srv.port from Document doc, doc.object(Private.Network Services) as >> srv order by srv.port >> >> ... translates to " select "port" field from all XObjects that are of >> class "Private.Network Services", ordering by "port" field " >> So this query would retrieve the value of "port" field from all of these >> XObjects (that we name "srv" in the query), wherever they are and whatever >> their count. >> >> >> >> >> 2012/11/12 crocket <[email protected]> >> >>> doc.getObjects was there since I had multiple instance of the same class. >>> >>> >>> >>> On Mon, Nov 12, 2012 at 8:32 PM, Jeremie BOUSQUET < >>> [email protected]> wrote: >>> >>>> Hello, >>>> >>>> I think this is not correct: >>>> select srv from IN (doc.getObjects("Private.Network Services")) srv order >>>> by srv.port >>>> >>>> Should be more something like: >>>> select srv.port from Document doc, doc.object(Private.Network Services) >>>> as >>>> srv order by srv.port >>>> >>>> Replacing the "select srv.port" by what fields you want to retrieve. >>>> >>>> Though obviously I'm not sure about what you wanted to achieve with your >>>> request to start with ... >>>> >>>> Br, >>>> Jeremie >>>> >>>> >>>> 2012/11/12 crocket <[email protected]> >>>> >>>>> Yes, I read it, and it seems collection member declarations don't work >>>> in >>>>> xwiki. >>>>> >>>>> >>>>> On Mon, Nov 12, 2012 at 6:13 PM, Jerome Velociter <[email protected] >>>>>> wrote: >>>>> >>>>>> Le 12/11/12 09:37, crocket a écrit : >>>>>> >>>>>> I tried to execute a Query and saw an error below. >>>>>>> >>>>>>> Caused by: org.xwiki.query.**QueryException: Exception while >>>> translating >>>>>>> [select srv from IN (doc.getObjects("Private.**Network Services")) >>>> srv >>>>>>> order by srv.port] XWQL query to the [hql] language.
