Replication-Subscriber Data Overwriting
Hi everyone, I am having a problem in Replication. Both Publisher and Subscriber are SQL SERVER 2008 R2 Enterprise Editiions. We have to configure replication between these two servers. The problem is, the replication should be Unidirectional, i.e,.. Subscriber data should not be replicated to publisher. Also, the data at the subscriber should not be overwritten. Sometimes data at the subscriber gets updated. So, replication should be configured in such a way that, the publisher data should be updated at the subscriber without overwriting the existing subscriber data. Is there any option in Replication to make this possible. What type of replication i shud use. Thanks in advance. Regards, Sai
If you use transactional replication to send data from the publisher to the subscriber you will still be able to update the data at the subscriber end. Any changes made will not be sent back to the publisher, you just have to be careful of any foreign key relationships etc. that could be affected by this type of change. Also be aware of what impact this would have on the data integrity/quality. If there is a clear case for wanting a modified copy of your data, then you can do this. Without any further information, it seems a strange thing to want to do.
Thanks for your answer. I am planning Transactional Replication with updatable subscriber. If triggers in Subscriber database tables is disabled,then no updated data will be replicated to publisher right?
