Maybe something like:
rule "Prix premier semestre"
when
p1 : Produit( eval(dDeb.isBefore(new Date(2010,1,1) ) ) )
then
p1.setPrix( 10 );
update( p1 );
end
Obviously you'll have to import whatever type of date you're using and
change the call to the constructor to match.
I may be wrong but I think you need to use eval here because you want to
create the comparison date within the rule. If you had already created the
date using "<" would be fine:
rule "Prix premier semestre"
when
p1 : Produit( dateProperty1 < dateProperty2 )
then
p1.setPrix( 10 );
update( p1 );
end

Hello,
Ok, I understand the problem. dDeb is indeed a Date type.
What is the proper/simplest way to achieve such a comparison ?
Thank you in advance for your help.
Regards,
Benoît

Hi,
What is the type of the dDeb field? It looks like you're trying to check if
a date is less than a string.

Dear all,
I am a newbie with Drools (Drools 5). I just want to make a date comparison
but failed until now. Here is my drl file :
package com.sample
import com.sample.DroolsTest.Produit;
rule "Prix premier semestre"
when
p1 : Produit( dDeb < "01-Jan-2010" )
then
p1.setPrix( 10 );
update( p1 );
end
I get a build error in Eclipse : Unable to create restriction.
This must be an obvious problem but I am struggling for a while now.
Any help would be appreciated.
Benoit
