SQL SERVER – Attach or Detach Database – SQL in Sixty Seconds #068

SQL SERVER - Attach or Detach Database - SQL in Sixty Seconds #068 68-AttachDetach-800x450 When we have to move a database from one server to another server or when we have to move a database from one file to another file, we commonly use Database Attach or Detach process. I have been doing this for quite a while as well. Recently, when I was visiting an organization I found that in this organization lots of developers are still using an older version of the code to attach the database. I quickly pointed that out to them the new method to attach the database, however it was really interesting to find out that they really did not know that sp_attach_db is now a deprecated method to attach the database. This really made me to do today’s SQL in Sixty Seconds. I demonstrate in this SQL in Sixty Seconds how to attach or detach the database using a new method of attaching database. Let us learn about Attach or Detach Database.

The code which I have used in this code is over here:

-- Detach Database
USE [master]
GO
EXEC MASTER.dbo.sp_detach_db @dbname = N'AdventureWorks2014_new'
GO
-- Deprecated Way to Attach Database
USE [master]
GO
EXEC MASTER.dbo.sp_attach_db 'AdventureWorks2014_new',
'E:\AdventureWorks2012_Data_new.mdf',
'E:\AdventureWorks2012_log_new.ldf'
GO
-- Correct Way to Attach Database
USE [master]
GO
CREATE DATABASE [AdventureWorks2014_new] ON
( FILENAME = 'E:\AdventureWorks2012_Data_new.mdf'),
( FILENAME = 'E:\AdventureWorks2012_log_new.ldf')
FOR ATTACH
GO

Here is the question back to you – Do you still use old methods to attach database? If yes, I suggest that you start using the new method onwards.

  • Pinal, Is there a practical difference here other than using a deprecated stored procedure that may go away in a future release? I understand that it’s just better to use what is intended by the vendor, but want to know if there is a different result here when using the old vs new method. Is the resulting database different in any way?

    You can do Attach/Detach with right click on the database to Attach/Detach too. These options are under the right click menu Tasks.
