Thanks for your reply.

Ah yes, I can see where you're coming from, and this methodology sounds good if you're running the same database in both locations - which would, of course, be sensible, but unfortunately isn't the case for me. (Source: FoxPro 2.6a, Destination: MySQL 3.23). Sorry, I should have made that clear. (I always seem to omit some vital piece of information out of my questions, in an attempt to remove the unnecessary!).
