Extract Index of Column as Flow Variable.

Hello KNIME - Professionals,


I´m currently trying to use the index of a column maximum as a flow variable. How can I extract the index?

I´m able to compute the maximum and somehow find it with the Rule Engine, but I´m struggeling to extract the index(i.e. Row Number).


Thank´s a lot for your help in advance!!!



The index of all columns you can get with the Extract Table Spec node

The max number of columns you can get with the Extract Table Dimensions node (This one also directly outputs this as flow variables)

Also the Scripting nodes, e.g. the Java Snippet or the Math Formula node, have the number of rows built into the node.

Is this what you are looking for?

Cheers, Iris
