How to avoid some numbers while generating random data from another table twice

I have places dataset and want to pick up values from that twice. first one as a source and the second one as destination how could I do this by picking source randomly and avoid destination to be the same as source?


Above is what I have done so far. I also put in blank places, zero but not helpful. And This is my schema if that helps. Mockaroo - Random Data Generator and API Mocking Tool | JSON / CSV / SQL / Excel
Thanks
