Column-level and row-level tracking in merge replication

Total: 11 Average: 4.6

In this article, let us review row-level and column-level tracking options in merge replication and how these are used in detecting conflicts during merge replication.

Merge Replication: Merge replication is used to replicate data in both ways i.e. from the publisher to the subscriber and from the subscriber to the publisher.

The initial snapshot of objects is taken and applied to subscribers. Incremental data changes and schema changes are tracked using triggers and applied to subscribers when the subscriber synchronizes with the publisher.

Replication can be set up between multiple SQL Server instance on the same server, OR it can be set up between multiple database servers within same or geographically separated data centers.

How to create Snapshot Replication

The concept of snapshot replication is simple. It generates and distributes the snapshot of schema and data of articles, appeared at a specific time and updates the changes on subscriptions. When we create snapshot replication, SQL Server creates a Snapshot Agent Job which generates a snapshot of publication database objects. Snapshot is stored on either network location or on the hard drive. You can define the interval to generate the snapshot using the SQL Job schedule. Read More

How to create Transactional Replication

In this article, I am going to demonstrate how to create transactional replication.

Transactional replication generated a snapshot of publication DB objects and data within it. After the snapshot is generated, all the data changes and schema changes occurred on the publisher database are delivered to subscriber databases. In transactional replication, data and schema changes are almost real-time, hence transactional replication can be used to offloading reports and sometimes can be used as DR Site.
