  • 0

I replicate a table from one SQL Server 2008 instance to another which already works fine. I’d also like to set a field in the replicated table on the target instance of the SQL Servers, but I’m not quite sure whether this is allowed (even though it seems to work).

Reason behind this: Replication from server A to B, processing of rows on server B and then setting (e.g. a flag such as “processed”) when the row has been processed. This information is not available on server A and can only be set on server B.

A more cumbersome way would involve a separate table on server B which would have to keep entries of IDs in the replicated table that have already been processed, but maybe this is not necessary?

    With Transactional Replication, by default the Subscribers should be treated as read-only. This is because if data has been changed at a Subscriber – whether it be inserts, updated, or deletes – it can not only cause data consistency errors, but a reinitialization could wipe the Subscriber data out as article @pre_creation_cmd is set to drop by default.

    If you’re going to be updating data at the Subscribers then I would suggest using Updatable Subscriptions for Transactional Replication, Peer to Peer Replication, or Merge Replication.
