Return Current Connection CName

All we need is an easy explanation of the problem, so here it is.

I’m wondering if anyone knows if there is a way to return the name that was used to connect to the SQL server rather than the actual server’s name. For instance I typically connect to the server via a DNS CName. But if I run this ..

select @@SERVERNAME

… I get the actual server name. I’m looking to find a way to get the CName with which I connected if it is even possible. Thoughts?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

The SQL Server instance has no notion of the name resolution the client used to connect to the server IP address so what you want is not possible.

@@SERVERNAME returns the server name or FCI network name, plus instance name for a named instance. The value is unrelated to the client connection specification.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
