Don't try to get the Token - hiding that sort of ugliness is the whole reason run-query* exists. Use a pattern binding instead:
(defquery my-query (declare (variables ?n)) ?f <- (room (number ?n))) (bind ?r (run-query* my-query 100)) (while (?r next) (bind ?fact (?r getObject f)) ;; ... now do something with your fact From: owner-jess-us...@sandia.gov [mailto:owner-jess-us...@sandia.gov] On Behalf Of Rejaul Barbhuiya Sent: Wednesday, June 26, 2013 6:22 AM To: jess-users Subject: Re: JESS: [EXTERNAL] Creating an eLearning system following TekMart example Thanks Ernest. In my program, I was using runQuery(arg0, arg1) and storing the result in a Iterator as shown below. Then I am storing the result in token and from token to fact. Iterator sno = engine.runQuery("session-number",new ValueVector().add(sidValue)); if (sno.hasNext()) { Token token = (Token) sno.next(); Fact fact = token.fact(1); Now, I want to use runQueryStar(). But I don't know how to read the Query Result. QueryResult sno = engine.runQueryStar("session-number",new ValueVector().add(sidValue)); if (sno.next()) { Token token = (Token) sno.????; what function should I use here? Fact fact = token.fact(1); On Mon, Jun 24, 2013 at 11:06 PM, Friedman-Hill, Ernest <ejfr...@sandia.gov<mailto:ejfr...@sandia.gov>> wrote: You can use a query to easily find your facts; see http://www.jessrules.com/jess/docs/71/queries.html and in particular, http://www.jessrules.com/jess/docs/71/queries.html#in_java -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users y...@address.com<mailto:y...@address.com>' in the BODY of a message to majord...@sandia.gov<mailto:majord...@sandia.gov>, NOT to the list (use your own address!)
