We have a database in which global updates must be periodically made to
multiple records, usually in the hundreds or thousands.
Is this a problem when using Merge replication? Because there are individual
merge triggers on each table, is it preferable to use a cursor to make global
changes?
Also, when using View Conflicts feature, is it safe to assume that record
listed as the winner has already been replicated to all locations? If so, why
does one have to click on either the Keep Winning Change or the Resolve With
This Data button?
Is there a way to globally accept all winning changes?
The global update will take far longer with merge replication. A cursor
solution might offer better performance.
Regarding the conflict viewer, it is safe to assume that the conflict has
been resolved with the publisher and one subscriber. It might then conflict
with another subscriber, so you can't assume it has been resolved
everywhere.
The keep winning change button and the resolve with this data buttons allow
you to clear the conflict (in other words accept it) or roll it back and let
the subscribers change win.

|||Thanks -- that's very helpful.
There are hundreds of conflicts that remain. Is there a way to globally
accept the winner so that the conflicts are resolved everywhere?
Also, will you be writing a book on Merge replication anytime soon?
