In Oracle, outer joins are called either left outer join and right outer join, depending on which table the joined table is.
Using "left" or "right" implies that this is an outer join, so you can drop the OUTER keyword in your queries. Thus, there's no different between RIGHT JOIN and RIGHT OUTER JOIN.

I assume that the Equi Join and Inner Joins means the sam e, correct me if i am wrong ??

If by Equi Join you mean using "=" on both columns, then that's correct.
