RE: Rebuilding MLOG tables

IIRC you need to lock the parent table in one session and then do whatever you need to do to the mlog table in a SECOND session (because, as another poster pointed out, the lock will be released too soon otherwise).

        Subject:        RE: Rebuilding MLOG tables

I don't think we can go with the truncate table thing since there is too much weirdness around here in when a client -- and there are multiple clients -- might update: Network problems, box crashed, sunspots (Don't forget about the sunspots!). So if there are entries still hanging around in the MLOG table, we want to keep them.
