We'll now look at how to configure or set up transactional replication between two databases using T-SQL.

Exercise 7: Creating the Publication

The first step in configuring replication is to create the publication. Follow these steps to create a publication for transactional replication:

Navigate to C:\Code\Lesson02\Transactional and open 1_CreatePublication.sql in SQL Server Management Studio.
In SSMS, from the top menu, select Query and then select SQLCMD. This changes the mode of the 1_CreatePublication.sql query to SQLCMD from SQL.
Modify the parameters in the script (shown in the following screenshot) as per your environment:
Figure 2.2: Parameters in creating a publication
The preceding screenshot shows the parameters being used in the script. The parameters are self-explanatory. The publisher and distributor are the same, as the publisher acts as its own distributor.
To run the script and create the publication, change the parameters as specified earlier...
