Here is the question, I received in the recent conference where I was presenting on Database Technology.
Question: What does it mean by Taking Database Offline and How to do it?
Answer: Taking database offline means, it will be no more available for database operations. Here are is how you can take your database offline.
-- Take the Database Offline ALTER DATABASE [myDB] SET OFFLINE WITH ROLLBACK IMMEDIATE GO
If you have previously taken database offline, you can once again take it online by running the following command:
-- Take the Database Online ALTER DATABASE [myDB] SET ONLINE GO
