Question

I need to create a SQL Server database that will recieve updates by some replication mechanism from another database. I need to write insert, update and delete triggers that will execute when this replilcation occurs.

I have experience with triggers but not with replication.

Should I use Transactional or Merge replication, or does it matter?

Will a trigger designed to run when a simple SQL insert statement is executed also run when replication occurs?

Answer 1

Well it depends.

If the updates that you intend to apply are to isolated tables i.e. all the data for a given table comes from the publisher only, then you can use transactional replication.

If on the other hand you are looking to combine table content i.e. an orders table, with orders being placed at both sites, then you would want to look into using merge replication.

With regard to triggers, there is a ‘not for replication’ configuration that you can apply to control their behaviour. See the following article for reference.
