Edson and Mark,
Thank you for your help.
I have the complete rule expressed in PASCAL-like language in the
following. Mark mentioned that "and" is not needed at top level but I
am not sure what syntax I can use to express the top-level "and" in
the following rule when the top-level "and" is used to connect Person
objects with complex matching logic.
Thank you for pointing out the diffrence between "and" in a rules
engine vs. normal programming language - I will do some more
experiments on that.
IF
(
(
(
(Person.Age > 35 OR Person.Age < 25)
AND
(Person.ZipCode =23546 OR Person.ZipCode = 68590)
)
and
(
(Person.LastOrderPrice > 300)
OR
(Person.TotalOrderNumber > 2)
)
)
OR
(
(
(Person.LastOrderCategory in ("098", "109") ) AND
(Person.ZipCode =74567 or Person.ZipCode = 23765)
)
and
(
(Person.LastOrderPrice > 1000 OR
(Person.TotalOrderNumber > 1)
)
)
)
AND // Top Level AND
(
(Person.Status="K" AND Person.IsDelinquent = "true")
OR
(Person.Status="T" AND Person.IsDelinquent = "true" AND
Person.DelinquentBucket = "3")
)
THEN Person.Status = "KT";
