CustomData on SQL Server connection string?

Analysis Services has a CustomData connection string property. You can put anything on it, then inside an MDX query you can use the CustomData() function to retrieve whatever was on the connection string. This is helpful for passing in a security token.

Is there anything equivalent for SQL Server?

I also posted this here, but got no response so thought I'd check in the security forum.

I'm not sure that there is a property which is exactly suited for passing custom user data, but there is a property which you might modify without affecting pretty much anything else.

The property is "Application Name" (SSPROP_INIT_APPNAME).

I see where you're going with that, but is there a SQL function to detect the application name from the connection string of the currently connected person?

Hi,

What you can do to get the application name provided in the property is to run a statement like this:

select program_name from master..sysprocesses where spid=@.@.spid
