Joiner Duplication Problem

Hello, I have a quick question.

I updated my KNIME into latest version which is 4.40. However I encountered problems when join two tables.

Is it possible that we join two tables that:

concatenate original row keys into one key without either separator or assign new row keys sequentially??

Looking forward to your answer?

Hello @donghoonshin,

No. But RowID needs to be unique so not sure this makes sense. Anyways you can use String Manipulation column extract RowID you want followed by RowID node to make those values RowID values. Still you need to ensure uniqueness within RowID node.
