SQL Server: Add existing mdf with new Database-name


we are using SQL Server  10.0.5500 on a SBS 2008 R2.
We made some backups of the *.mdf and *.ldf Files within the DATA-Folder of the SQL-Server. Now we need some of the data back and don't want to destroy the running system/database.
So we need to add the database to the server management studio and change the name so the import won't overwrite the existing (and running) database.

How do we do this?
Is there any possibility to create a new databasemodule? If so, we can add the database to the new one and create some sql-statements to change/add the running database.

Any help ist appreceated.

P.S. We also could create a VM and import the data to the VM-system. After that we can create the sql-actions, but this seems to be a lot more work ...

Always use a command, such as above for this, and not the GUI, because:

1) the GUI can be flaky and unreliable for this
2) with the command, you can call the command back up later and see exactly what you specified
Sounds like you want to do a CREATE DATABASE with the FOR ATTACH clause


It is as straightforward as:

create database dbName_BACKUP
   ( filename = 'path to mdf' ),
   ( filename = 'path to first ndf' ),
   ( filename = 'path to last ndf' ),
   ( filename = 'path to first ldf' ),
   ( filename = 'path to last ldf' )
for attach;

Open in new window

Hope that helps!  As an aside, I would move the backups of the mdf/ndf/ldf's that you guys made into a subfolder to prevent confusion.  And once you create the new database (provided it's in the same instance), you can move data from one to the other, just be careful =)  I would, personally, recommend that the direction of data flow always be towards the copy and when you have it to where you want it, detach both dbs, and then create the production DB from the modified files.

Just attach database using the SSMS and give a new name to Database.

sp_attach_db 'DBName', 'DBfilePAth'
