Knime Crash Course: The Rule Engine Node

[@busyshah]

Very well explained. So simple to understand. I have one question, if 'delete' is something we want to update if our condition(s) is true. Then why we use True => for other cases?

Thanks a lot for the comment! in the end, we don't need it for this specific example, you're absolutely right about this. It was basically just to show how an optional "else" argument would be phrased. It's basically comparable to the last argument in an Excel IF formula, which is also optional. But sometimes you want to have this "else" option and that's why I showed it. Hope that helps to clarify! :)

Hi, I would like to post a question, I have not yet found an answer on how to use the rule engine to apply a rule to the entire table (all columns). Is there an easier way to do that other than to simply choose all columns and apply the rule to them?

to do. You can use the Column Expressions Node and some very basic JavaScript logic. Don't worry, you don't have to learn to code. Just Google e.g. for IF functions. Happy to provide an additional video in the next few days. Of course, it has to be the same logic to all columns.
