Details:

help warning yields 

 -- warning (TEMPLATE, ...)
 -- warning (ID, TEMPLATE, ...)
 -- warning ("on", ID)
 -- warning ("off", ID)
 -- warning ("query", ID)
...


which means that querying does not yield a return value. 
This is not true, which is illustrated by the following. 


octave:3> a=warning("query", "Octave:divide-by-zero");
octave:4> a
a =

  scalar structure containing the fields:

    identifier = Octave:divide-by-zero
    state = on
