Discussion
Outer join is the same as equi-join, except one of the duplicate columns is eliminated in the result table.
Answer: B
Correct answer: False

An outer join does something else entirely: it keeps the rows that have no match on the other side, filling their missing columns with nulls. The statement has attached one join’s definition to another’s name.
