Need help to restore multiple databases/bak files from one folder

In SQL server 2008R2, I am trying to restore multiple databases/BAK files located in one folder only, using a SQL query given here - http://www.karaszi.com/sqlserver/code/sp_RestoreFromAllFilesInDirectory_2008sp1.txt

It uses a stored procedure like this, the code for which is given at the end -

exec sp_RestoreFromAllFilesInDirectory 'C:\Mybakfiles\', 
'D:\Mydatabasesdirectory\' , 
'C:\MylogDirectory\'

Folders invloved - 'C:\Mybakfiles\', 'D:\Mydatabasesdirectory\' , 'C:\MylogDirectory\'

You should know the path to the first folder. The second and third can be found with a query or by SSMS. For the query, refer to alex aza's answer at - What is the most efficient way to restore multiple databases in SQL 2008 . I have also given his query at the end.

I copied all my BAK files to - C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\

Then, I entered executed the SP as follows -

exec sp_RestoreFromAllFilesInDirectory 'C:\Program Files\
Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\', 
'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL
\DATA\' , 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\
MSSQL\DATA\'

and got the following sample output -

RESTORE DATABASE AdventureWorksDW FROM DISK = 'C:\Program Files\
Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\AdventureWorksDW.bak' 
WITH MOVE 'AdventureWorksDW_Data' TO 'C:\Program Files\Microsoft SQL 
Server\MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW_Data.mdf', MOVE 
'AdventureWorksDW_Log' TO 'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW_Log.ldf'

Problem - I refreshed my server in management studio and saw no new databases. Why ? Have I restored my Databases correctly ? If not, how do I do it using the code I have provided below ? If you think that code is not good, is there any other reliable way to do it ?

PS - Its a shame that MS does not let you do this easily.

Thank you so much for this very helpful script.

I have added the new columns for newer versions of SQL Server as well as added the alter database to single-user mode before the restore and alter it back to multiuser after the restore. By default, these options are commented out.

--If you need to overwrite the existing database uncomment this 
--SET @sql = 'ALTER DATABASE [' + @DbName + '] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
--RESTORE DATABASE ' + @DbName + ' FROM DISK = ''' + 
--@dirfile + ''' WITH  FILE = 1, MOVE ' 

--If you need to overwrite the existing database uncomment this as it will reinstate the database to multi-user
--SET @sql = @sql + '''' + @LogicalName + ''' TO ''' + 
--@DestDirLogFiles + @LogicalName  + '.ldf '', NOUNLOAD,  REPLACE,  STATS = 5
--ALTER DATABASE [' + @DbName + '] SET MULTI_USER
--'

first thanx for the script:) kindly check the columns RESTOREHEADERONLY and FILELISTONLY. You need to add some columns. At least mine worked when added new columns.

To make the script work on MS SQL Server 2012, add another column to #bdev table:

Containment int

Also, I had to change a few columns in #dbfiles table to be bigint.

First thank you for providing the script of sp_RestoreFromAllFilesInDirectory as the creator homepage no longer available.

The script you provided only print the generated sql so all you need to uncomment the line:

EXEC(@sql)

I know the question is too old but that my save someone else
