1. Is it true to say that a Full Outer Join will always return the same amount of rows as either a Left or Right Outer Join?
2. Would a Full Outer to be used in situations where you didn't know (nor care) which of the two tables had the more rows? where instead you need all matching and non-matching rows regardless?
3. Or do Full Outer's make more sense when you have to outer join multiple tables(more than two)?
