ouch! It works. Yes, it is not related directly with XWiki however, in any case, I updated the documentation of the query module to help other newbies like me =) Danilo 2014-07-17 18:22 GMT-03:00 Sergiu Dumitriu <[email protected]>:

I.e. append "order by xxx()", where xxx is what the database you're using knows.

rand() seems to work for both mysql and hsqldb.

Hello XWiki Devs,

I have a specific class in the XWiki (TestClass) with more than 50 items. However I would like to retrieve, through the HQL statement, just 5 random results.

I know how to set the limit, using the "setlimit", however I don't know and I did not find if there is a way to retrieve a random result.

Is it possible, or I will need to make a hql that returns all results and after that take 5 itens randomly?

Thanks
