Which type of join returns all rows from one table and only those rows from a secondary table?

Options
- Inner join
- Self join
- Outer join
- Left join

CORRECT ANSWER : Outer join

Discussion Board
poorly worded question

Correct answers are:
Left join
and
Outer join

Why?
Because Left join = Left Outer join

The question does not specify: is it left or right join.
So both answers are proper, sadly :(

Outer join is a more general answer but "Left join" is proper also.
