You could use a server-scoped DDL trigger to run the procedure at login.
Technically, a function can't be run, just called. Functions are used to return a value, not to change things in the database.

I would like to have it at database level. Depending on what database is getting accessed, I would like to set parameters.

Let me give some background.
We use a ERP System , In the current version we have a table called CO.
In the New release they replaced CO table with CO_MST table and created a view on CO_MST
View definition looks like . create view co as select * from CO_MST where site_ref = CONTEXT_INFO()

That's why I wanted to set a CONTEXT_INFO() for every SQL session automatically (I was planning to use stored procedure) so that my query (select * from co) will work.
I would like to set CONTEXT_INFO() based on the database in use.

Someone correct me if I don't have it right, but I'm pretty sure you'd need to set that in the application that creates the session.
