Construct a Right Join with SQLite

I built a workflow that does that also to play around with SQLite and to see what it could do.
I have two databases that both have two tables named “table_01” and “table_02”. They have the same structure Col1 … but two cells are different than the others. Task is now to isolate these cells and leave the ones out that are identical
