[rules-dev] Valid or not valid: 1 < foo < 10?

[Wolfgang Laun]

Developers:

it would be *very nice* to have a clarifying statement as to whether
the triplex relational expression is valid or not, so that a proper
issue might be raised.

Status in 5.3.0: accepted by the DRL parser and resulting in unknown semantics.

Thanks
Wolfgang

The Drools documentation states that the left side of any binding
pattern of any conditional element must be a read-only property of the
element (or nested property).  As such you must rewrite your rule.

Try this:

	rule "rule_Name"
	    when
	        per: Person(age >= 50 && < 100, income >= 10000 && < 50000,
occupation == "Business", category == "Military", location ==
"Bangalore", custype == "Individual")
	        pri: Price((price >= 20 && < 30) || price == 1)
	    then
	        System.out.println("Success");
	end

Hi,
   I want to know, how to write rules in two fact's fields?

I used two facts, it will take AND condition or OR condition in between the
two facts.

Please check my code....

package Project
import com.sample.Person;
import com.sample.Price;
	
	rule "rule_Name"
	    when
	        per:*Person*(50 <= age < 100, 10000 <= income < 50000, occupation
== "Business", category == "Military", location == "Bangalore", custype ==
"Individual")
	        pri:*Price*((20 <= price < 30) || price == 1)
	    then
	        System.out.println("Success");
	end


The both fact values are satisfy means, what is the output?

I got output, even the *Price* fact's value is wrong. (price == 100)

Please slove my problem........!!!!
