Is the identification number (ID) of the database to be returned. database_id is int, with no default. If no ID is specified, the current database name is returned.

If the caller of DB_NAME is not the owner of the database and the database is not master or tempdb, the minimum permissions required to see the corresponding row are ALTER ANY DATABASE or VIEW ANY DATABASE server-level permission, or CREATE DATABASE permission in the master database. The database to which the caller is connected can always be viewed in sys.databases.
