Without the ability to modify the application which uses a direct database
connection, you’d need to modify the server code or run some kind of
proxy/man-in-the-middle server you can program.  I would avoid updating the
table on write though - just keep a cache of sorts somewhere and
periodically compare the cache to the live table.
