Joiner Not Working in Loop.

[ipazin]

Hello @saiakula15,

and welcome to kNIME Community!

Not sure you need loop if all you want is to eliminate columns from source file based on a header list from another file. All you need is Reference Column Filter node.

If you need to make Joiner node work in a loop take a look at this topic:

Joiner node in Loop

Hi all! I’m trying to use Joiner node in a loop. I start loop with a Table Row To Variable Loop Start which takes table name as input. That table is read from one database and then compared to the same table in another database. In order to do this I’m using Joiner node for Right excluding join. In order for this to work properly I would have to make Joiner node to take all columns from both tables (they have same names) as joining columns. Ideas? Br, Ivan
