Hello

Could someone explain the differences between RIGHT OUTER JOIN and RIGHT
JOIN?

If outer allows a table to have nulls and right join dont, wouldnt make any
sense since there are inner join in that case.

They are essentially the same thing. The keyword OUTER is optional when
RIGHT is specified because the keywords RIGHT, LEFT and FULL imply an outer
join.

RIGHT JOIN and RIGHT OUTER JOIN are exactly the same thing. As soon
as RIGHT or LEFT is specified by definition that makes it OUTER, but
the work OUTER is optional and may be left out.

Same thing. The word OUTER is optional.
