View Full Version : Regarding drools rule engine.

I am trying to explore drools decision tables for my project
From whatevr infrmation i have gathered till now,we can only apply logical “AND” operator for decision table columns.

I would like to know that is it possible to apply logical “OR” operator to the CONDITION columns in the decision table, because I have some data for which I need to apply OR condition.

Your inputs in this regard would be really appreciated.

You'd be better off asking this in a dedicated Drools/JBoss Rules forum -- Pentaho's only involvement is with exploring integration with the rules engine.

That being said, adding OR conditions can result in odd behaviors in the Rete model -- I ran into that in JESS a few years ago when my result set expanded when I added a new criterion. I ended up coding the solution in eCLiPse using a finite domain solver based on the advice from the JESS list.
