"Left Join" versus "Outer Join" in MySQL

Last Modified: 2008-02-01
Someone asked me what is the difference between a "Left Join" and an "Outer Join" in MySQL.

My understanding is that they are the same.

Essentially there are three types of join: Left Outer, Right Outer, and Inner. All the others are just names for these.

Is this correct?
