Thank you. I appreciate your comments.

(I am amazed that the language allows for something that appears to be
very useful but is not functioning as described or is considered poor
design.)

I was trying to reduce the complexity of my client application.

What would be a more-effective use of the RDBMS?

Do you think I should use the client software (Delphi, in my case) to
do the lookup in order to display the looked-up value of a
lookup-field?
