So, my question is how can multiple values for a single
field get represented in a single row and receive the
benefits of an index? How can this data be represented?
Nice puzzle.
At first I thought it couldn't be done, given all your
constraints.
But there is one way.

Well, the only thing that matters is that you are returning the same number
of columns with, presumably, the same data types in both queries. Obviously,
UNION wouldn't be helpful if you had 2 columns in the first query and 8
columns in the second.

Yes. You can, for example, use the mysqldump program. mysqldump
is a MySQL client program that, like all MySQL clients, requires
the server to be running.

Does it? In your original question, you'd indicated that you only

How about a TEMP table? You can create a temp table, fill it with the
results of your UNION statement and then JOIN it with this new UPDATE
query - that should get you what you need. Note that this is a workaround
for MySQL - in other DBRMS, you can use a sub-SELECT to
