SQL SERVER – Identifying Deprecated SQL Server Features with Extended Events

In this blog post with the help of Extended Events, we will learn how to identify all the deprecated SQL Server Features. This feature can be very much handy when we are changing the compatibility of SQL Server and we want to check what are all the deprecated SQL Server features we are still using in our active code.

Now let us run any deprecated feature in SQL Server and see the output. As I am using SQL Server 2017, I know that SET ROWCOUNT feature is deprecated in SQL Server 2017. Let us run the same command in SQL Server.

Next, change your focus to live data on the screen and you will be able to see that extended event screen will catch the deprecated event in the windows and display all the necessary information.

I guess it is very easy to know what are the deprecated features you are using across the database. We use this feature all the time during Comprehensive Database Performance Health Check.
