I am working with sql and doing exercises from
w3resource. There is exercise where they used NATURAL JOIN as solution: https://www.w3resource.com/sql-exercises/sql-joins-exercise-7.php
As I understand NATURAL JOIN is just shortcut to avoid typing.
But exercise require that
the same column of each table have to appear once and only the relational rows will come
. How that can be done with INNER JOIN?
