It is if you use table defaults.  (see 'create table', and 'netval()')

Thanks for the tip; Richard Lynch <lynch@lscorp.com> had sent me the
same information via email.  I was unaware of the "default" clause
which certainly makes this piece easier.

I guess I'm still stuck with writing C-code to get cascading deletes,
but I can probably postpone that requirement for a while....

Hi there,

Please see subject.
I guess the problem is, that my unix shell doesn't accept them.
Are there any escape sequences I could use?
