Table A and table B

80 rows of table A matches in table B

I need to find other 20

hi @navi1993 and Welcome to the KNIME world,

there is a specific node for this, which is called Reference Row Splitter.

you should have one column as identifier in each table, which will be compared.
Your workflow should look like shown here…
