DB_NAME(@dbID) returns Null

[ChristopherElliott]

In my example sys.Databases lists my database_id as 6 but if I query DB_ID() it returns 5. The script uses database_id applied to DB_NAME and it returns null in my case. Googling is suggesting that this ID can't be relied upon and that the db name should be used instead.

Proposed a fix that seems to work for my case: #269
