I still see that link taking me to an article about Data Compression Double Take which seems different than SQL and T-SQL for Beginners or is that where it is supposed to link to?
EDIT - you also appear to have posted this in the future?
The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
