        How to implement IF-THEN-ELSE condition in one rule.

        example

        if name="latha"
        then status="valid"
        else status="invalid"

        or any nested if-the-else..

        one more query is i need to take record from sql database table based upon some condition (staus="valid") and implement some rules

          unfortunately none of the patterns can be done easily. The straight if-then-else can be implemented by priority your rules and use either vocabulary or interim XML as "Variable" for condition set or check.

          I might be wrong but the nested condition just can't be done by BRE…

            There is no direct way to do "else".

             The normal way to achieve this in one policy is to have two rules, one which is the "not" of the other.

            Or, as the previous poster suggested, you can create an intermediate result and check that in another rule. However, this tends to produce logic which is very hard to read.

             By the way, if I understand correctly, not having an "else" clause is quite normal in rules languages.
