SQL Toolkit – Get List of Database Options and Features

–By Lori Brown

I am going to start up a thread with some queries that I consider to be important to DBA’s. As a consultant, many times we have to start managing SQL instances without any knowledge of why it has been configured in various ways. We usually try to work with our clients to figure things out but many times even they don’t know what has been done to the SQL configuration and database options or features. This can happen when a software vendor is allowed to set up the SQL instance or when a developer or DBA enables certain things so that work can be done. I have some scripts that I keep in my Toolkit and can use when I need to better understand the environment. At least armed with a little knowledge, I can ask questions and help my clients better understand things.

Here is a query that I use to find out what database options have been set as well as what advanced features maybe enabled. I tried to make the output display in plain English so that if I have to pass the info on to a client, they can understand it as well. Please note that at the end of each column, I have put a comment indicating if the feature is version specific. If you don’t have that version of SQL, simply comment out the lines that don’t apply to you. As new versions of SQL come out, I’ll try to test and keep things in the Toolkit up to date.
