Even if somebody's built it for MySQL, I'd still have to code my VFP app
to query that History table to show the changes made by who and when.

I did a project many moons ago where we used the INSERT, UPDATE and DELETE
triggers in a Foxpro 6.0 DBC to track field level changes by users by date and
time. It was fairly successful other than making our data very dependent upon
maintaining a valid DBC. Later, we extended program by adding a connection to a
FirebirdSQL database which was then use by a Java-based web front-end. In the
case of Firebird, I found a tools called IBLogManager which did the same thing
at a SQL level using the same sorts of triggers.
I wonder if someone hasn't already created a similar tool for MySQL that you
could take advantage of.

Subject: How best to do an audit trail of changes (EASILY WITHOUT THE NEED FOR
A DBA)
VFP9SP2 app, MariaDB 10 (MySQL) backend.
One of my clients asked about a history of price changes. Easy enough
to implement programmatically for the few price fields, but then I got
to wondering if simply putting code in the ON UPDATE trigger to send the
old record to a "history" table would be a more complete (and long term
EASIER) solution, whereby my app would query the "history" table for
changes.
Your thoughts for tracking price (or other) changes?
