Keeping all rows which match a value of a certain column from row0

[knimerin]

Hi,
I want to keep all rows which match the value of a certain column from row0.
Let’s say, the table has a column called cluster. If row0’s cluster value is “cluster0” I want to keep all rows with cluster0 in it’s cluster column. How can I achieve this effectively?

Hi @knimerin
Could you please upload a minimalist workflow with data. I will complete it with the solution and upload it back.

Best regards,

First filter Row0. Then join filtered row to the original table using corresponding columns…

Hi there @knimerin,

I would use Table Row to Variable to get values from first row in flow variables followed by Row Filter node that is parameterized with flow variable to include row you want.
