i need some urgent help with the node rule engine.
I want to check some Column if it contain values with “123” then knime should create a new column with “123”
I have used the node Rule engine in cobination with LIKE:
// $Column1$ LIKE “123” => “123”
and Option append column is activated
(“place marker123place marker”)
But in the createt Colum i have only missing values. Have somebody an idea? Hope you can help me thanks regards Chris.
Use a wildcard-sign in your rule: $your_column$ LIKE “123” => TRUE
@HansS, Chris has already used the wildcard. It appears as italic text due to the asterisk, like your post.
@Chris87, this is weird. Can you share a sample of your dataset where 123 is contained?
Hi @nicks and @Chris87
See this wf KNIME_project2.knwf (16.6 KB): using an * works.
Thanks a lot for your help i have copy your code and now it is working i dont know why but it works. Thanks to all have a nice day regards
