> In a drool template, if i am loading rules from a database, then as per my understanding each row in the database table represents a rule. So a drool template will generate a drl file in the following way : 
> rule 1
> when 
>       condition(first row of db)
>       action
> rule 2
>       condition(2cd row of db)
> then
>        action
> etc.
> My requirement is to have a dynamic drl generated in the following way :
> rule 1
>  when
>        condition 1(1st row of db)
>        condition 2 (2cd row of db)
>        condition 3 (3rd row of db)
>        etc
> then
>        action
> end
> Please suggest a way to do this.
