Not all tables have a primary key. I want to have a standard way of
referencing a lot of different tables to calculate checksums for
records. Instead of adding an autoincremet to each field, it would
be very helpful if I could access the RDB$DB_KEY for this.

My question is realyl that if the facility is present, and I can see
from other messages that one would appear to be able to use it, how
do I get access to the RDB$DB_KAY in my code. I understand your
comments about the use of primary keys, but, for various reasons, I
need access to the RBD$DB_KAY.
