[rules-users] Drools Language Enhancements

[Raja Sekhar]

Hi All,
I came across this link

https://community.jboss.org/wiki/DroolsLanguageEnhancements#jive_content_id_SQL_Group_Operators

select  location, age, avg(income), min(income), max(income) from Person
group by location, age  //SQL



acc( $p : Person();
        [$l, $a] : distinct( $p.location, $p.age) )
acc( $p : Person( location == $l, age == $a );
       $avgIncome : avg( $p.income ) ,
       $minIncome : min( $p.income ),
       $maxIncome : max( $p.income ) )



If we wanted to make a  list of lists we could add:

acc( $l : List() from [$avgIncome, $minIncome, $maxIncome],

       list( $l )


Can some give me specific example with this


Regards,
