Hi Asish,
As of now, it is not possible for a query to read the data coming from another query. It is in our plans to add a feature allowing to do that, in the upcoming releases.
Right now it is only possible to add additional data from the same query.
Stay tuned for more information about that new feature (not sure yet if that'd be an enhancement to the current query activity or a new activity that will allow to add additionnal data after any other activity).
Hope this helps,
Florent
