Full Outer Join (More Than Two Tables)
I'm not even sure myself if this makes sense but can you join more than two tables with the new FULL outer join syntax.
For example if I have three tables can I join all three hoping to return all rows on all three tables only matching rows where the join condition is satisfied.
If this is possible, or even logical, give a code example.

taking a 2 table example, customers and invoices, inner join them and get a list of all invoices that have a valid customer (or all customers that have a valid invoice - it's the same) left/right outer join them and get either all customers with their invoices, if they have any, or all invoices with a valid customer, full outer join will list all customers and all invoices, showing where they link
