SQL Server restore proc with database name parameter - sql

Question

Looking for a stored procedure to restore from a .bak file, but would like to be able to enter the db name as a parameter, i.e. Exec sp_restore #dbname
The paths to the .bak will be identical for all the dbs i.e. all dbs are dev copies of the same production backup.
Each .mdf and .ldf will have the same name as the db itself i.e.
dbname = #dbname, mdf = D:\data\#dbname.mdf, ldf =D:\data\#dbname.ldf
The paths to .mdf and .ldf will be the identical for each db, i.e. D:\data\#dbname.mdf

Answer 1

Using Sql Server Management Studio, you can start performing a restore operation. Before completing the task, you should be able to see a "Script" button. This will create a script with all the parameters you have manually entered, including mdf and ldf location. You can then save this script and execute it at will. You can also modify the resulting script to make the database name an input variable. You can do anything really. It's SQL!
A sample script that restores a database and changes mdf and ldf file locations would look like this:
RESTORE DATABASE [example] FROM DISK = N'E:\Backup\example.BAK' WITH FILE = 1, MOVE N'ExampleData' TO N'E:\dbfiles\example.mdf', MOVE N'example_log' TO N'E:\dbfiles\example.ldf', NOUNLOAD, STATS = 10
GO
You can read more about the RESTORE statement
You can then insert the script in a stored procedure as such:
CREATE PROCEDURE RestoreDb
-- Add the parameters for the stored procedure here
#dbName nvarchar(50)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
RESTORE DATABASE #dbName FROM DISK = N'C:\Data\MSSQL\Backup\lolwut.bak' WITH FILE = 1, NOUNLOAD, STATS = 10
END
GO

Procedure for restore DB from bak-file #DeviceName. It works with DBs, wich have two logical files.
How to use:
EXEC RestoreDb #dbName='qqq', #DeviceName = 'D:\temp\1\R.bak'
Sorry for my English, I improve it.
CREATE PROCEDURE RestoreDb
#dbName NVARCHAR(50),
#DeviceName NVARCHAR(400)
AS
SET NOCOUNT ON
DECLARE #Cmd NVARCHAR(1000),
#DataLogicalName NVARCHAR(200),
#LogLogicalName NVARCHAR(200),
#DatabasePath NVARCHAR(200),
#DataPath NVARCHAR(300),
#LogPath NVARCHAR(300)
CREATE TABLE #Files
(
LogicalName nvarchar(128),
PhysicalName nvarchar(260),
[Type] char(1),
FileGroupName nvarchar(128),

SELECT #DatabasePath = 'D:\data\'
SELECT #DataPath = #DatabasePath + #dbName + '.mdf',

SELECT #Cmd = 'RESTORE FILELISTONLY

INSERT #Files
EXEC (#Cmd)

RESTORE DATABASE #DbName
