Why would that be an issue of consequence?
You add some columns to a table. The rest of the software
can ignore them. (Unless you use select * or other black arts,
said rest might never see the new columns.)
Yeah, there are black arts involved. My framework has some generic
code that expects to be able to process every field in certain types
of tables. If there is not corresponding code for each field in
certain subclasses, errors are thrown. Probably a poor design choice
in retrospect, but the choice was made in 2004 and rectifying it
would require a huge amount of work.
Oh, my! (Alternative pronunciation: "You poor bastard!")
Can you modify the framework? One kludge would be for it to
ignore certain columns, say those starting with a certain prefix.
I have a couple of anvils around my neck, too. They prevent my
system from easily being multi-user. One was a reasonable trade-off
at the time, but the downside continues to bite. The other was an
argument I lost, because my boss does not understand relational databases.

No, I don't have a loader program. I would have to introduce
internet download capabilities in order to provide that, and that's
a headache I don't need.
Loader programs are not difficult to set up on a local
network. Still not an option?
