Hello, I would like to take 100 sampling facts for rule and persist it in the db and ignore other data. How Can I maintain the counter? as global variable? Please clarify with sample code. I tried following way and but it does not work as expected. Ex: global Integer counter; rule "get sampling data" when fact : Foo(some condition) && eval(counter <= 100) then counter++ // do some condition end -- View this message in context: http://www.nabble.com/having-counter-in-drl-tp20904469p20904469.html Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Thanks all for the reply. I executed following rules after adding Event fact id ranges from 1 to 8. Output is given below. counter rule was not executed for distinct event fact. some help please. output : ----------------------------- adding counter new count value: 4 , event : 8 new count value: 3 , event : 7 new count value: 2 , event : 8 new count value: 1 , event : 7 ------------------------------- rule "init" lock-on-active true when then System.out.println("adding counter"); Counter c = new Counter(4);// init with max count value insert(c); end rule "counter" no-loop true when event : Event() counter : Counter(count > 0) then System.out.println("new count value: "+counter.getCount()+" , event : "+event.getEventId()); counter.setCount(counter.getCount()-1); update(counter); end dave sinclair wrote: > > Make counter an object > > when > $counter : Counter(value <= 100) > ... > > > On Mon, Dec 8, 2008 at 5:05 PM, techy <techluver007(a)gmail.com&gt; wrote: > >> >> Hello, >> I would like to take 100 sampling facts for rule and persist it in the db >> and ignore other data. >> How Can I maintain the counter? as global variable?
