What is the function of a right outer join?
(a) It preserves tuples only in the relation named before the operation
(b) It preserves tuples only in the relation named after the operation
(c) It preserved tuples in the relations named on both the sides of the operation
(d) It does not preserve any tuples on either side of the relation
The question was posed to me in an online quiz.
My doubt is from Join Expressions in section Intermediate and Advanced Sql of RDBMS
