I have finished a rule as follows:
rule "Your First Rule"
when
ExpressItemTemp($eid :eid)
not (TreatResult(id==$eid))
$total : Double(doubleValue >=138) from accumulate ($eit: ExpressItemTemp(itemid in ("7096760680","3096780174","2251556006","2252191048","2254989638","2251521962","12203694113","2252461508","2588839002","2254940542","2252775410","2252775398","2254081374","2251552580","2251509802"),eid == $eid, $rel : (itemprice*itemnum-discount)),sum( $rel ) )
then
System.out.println($eid+":"+$total);
insert(new TreatResult($eid));
end
but,how can I doing the same work with decision table?
