Hello,

   What is the difference between calling insert and update in a rule file? When I use insert my queries don’t work, but if I use update they seem to. I don't mind using update, but I would like to understand the difference between the two. Here is my rule file.

    rule "Add person to math class"
    no-loop
        when
            person : Person(likesMath == true)
        then
            person.setClassName("Math");
            insert(person);
    end

   I also have a query:

   query getPeopleForClass(String _className)
      Person(className == _className)
   end

   When I add two facts to working memory, where the likesMath attribute is true, then run my query I get zero results back. When I change the rule, "Add person to math class", to use update(person) instead of insert(person) two students are returned.

  Any help would be appreciated.

Thanks,
Dan
