SQL SERVER – T-SQL Script to Take Database Offline – Take Database Online

Blog reader Joyesh Mitra recently left a comment to one of my very old posts about SQL SERVER – 2005 Take Off Line or Detach Database, which I have written focusing on taking the database offline. However, I did not include how to bring the offline database to online in that post. The reason I did not write it was that I was thinking it was a very simple script that almost everyone knows. However, it seems to me that there is something I found advanced and that is simple for other people sometime, in this case, I thought simple and is not simple for someone. We all have different expertise and we all try to learn new things, so I do not see any reason as to not write about the script to take the database online.

-- Create Test DB
-- Take the Database Offline
-- Take the Database Online
-- Clean up

Joyesh let me know if this answers your question.

  2. Hello Pinal,
    I am new to SSIS and would like to if you have experience in this area. I am looking for the correct steps in creating dynamic connection in SSIS to gather waits stats on all servers (40 plus servers). When I try to create this on my own, i seem to get stuck on trying to get the foreach loop container. Thanks for you help.

  8. Problem:

    We have one online database and it’s configure that on client sight
    but some time it’s suddenly disconnect from the client’s configuration and they are not able to configure again and have to call us.
    when we show that database in the SSMS then when click on that says error like
    you are not accessible that database
    at that time we have to that database first offline and then again put it online.

    What is the solution of that please help us
    I am very frustrated this problem now.
