Home -> Community -> Usenet -> c.d.o.server -> Foreign Keys - unknown characteristic
Hi all.
I refer to a statement in Steven Feuerstein's
Oracle PL/SQL book (2nd edition) (page 601 for
those of you who have it), where he makes a comparison
between foreign keys and REFs in Oracle 8.
In this table, he says (and I quote):
"...foreign keys have a little-known ability to point to all of several possible parents"
Can anyone explain to me what this might mean ?
Thanks
