Hi Nuno,

you are right -- if you navigate away from the master table in a
master-detail relationship, and if you don't consider full outer joins ...

Kind regards,

How?
If it finds a corresponding row, it puts its column value in the output.
If it doesn't, it puts a NULL there.  How can that add rows?
