[SOLVED] Is there a way to call query from a rule in DRL file?

Is there a way to call query from a rule in DRL file?

I have a requirement to chain a window rule to a window rule. My use case is :

If the occurrence of temperature > 50 in 5 min window is greater than 10 then find the max(average) of the temperature in that window frame or any other chain rule on that window data.

I tried the following aprroach:

query getFactFromMemory(long time)
   $fact : Fact(timepoing < (drools.getWorkingMemory().getSessionClock().getCurrentTime() + time))
end

rule "window rule"
when
   //condition
then
   //action
end

rule "chain rule"
when
   //condition
then
  getFactFromMemory(1000L)
 //loop over facts and then perform some action
end

I am getting errors while calling the query. I tried calling the query in when part and assigning it to a variable but that also giving error (Query's must use positional or bindings, not field constraints:1000L and Query binding is not supported by non-abductive queries : $variable).

Can anyone help me in solving this error or suggesting any other approach to the problem?

Solution

We can get drools runtime object inside drl by invoking drools.getKieRuntime(). So, the working rule for the question is:

query getFactFromMemory(long time)
   $fact : Fact(timepoing < (drools.getWorkingMemory().getSessionClock().getCurrentTime() + time))
end

rule "window rule"
when
   //condition
then
   //action
end

rule "chain rule"
when
   //condition
then
  getFactFromMemory(1000L)
 //loop over facts and then perform some action
end
