Restore SQL Server 2005 DB on 2005 Express

Question:
We have a SQL server 2005 database in a shared production environment.
We do a backup of this database and want to restore it in a development environment having only a SQL-2005 Express Edition.
You cannot restore the prod database using the Management Studio Express.
What to do??




Answer:
You have to script the restoration.
Do not create a database - it is done by the "Restore with move" command.
If you have already created a db and you want to restore into it, then try to use

RESTORE FROM DISK ="path_to_your_backup_file" 
WITH REPLACE

Here is a sample-script and some links we used.


Declare @newTargetDBName nvarchar(50)
Declare @newTargetDataFileName nvarchar(255)
Declare @newTargetLogFileName nvarchar(255)
Declare @newTargetSysFTName nvarchar(255)

Declare @restoredSourceFile nvarchar(255)
Declare @restoredSourceLogicalDataFileName nvarchar(255)
Declare @restoredSourceLogicalLogFileName nvarchar(255)
Declare @restoredSourceLogicalSysFTName nvarchar(255)

Set @newTargetDBName = 'mydbprod_20091208'
Set @newTargetDataFileName = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\mydbprod_20091208.mdf'
Set @newTargetLogFileName = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\mydbprod_20091208_log.ldf'
Set @newTargetSysFTName = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\mydbprod_20091208_sysft'

Set @restoredSourceFile = 'E:\ReleaseBackups\mydbprod_20091208.bak'
Set @restoredSourceLogicalDataFileName = 'mydbprod'
Set @restoredSourceLogicalLogFileName = 'mydbprod_log'
Set @restoredSourceLogicalSysFTName = 'sysft_mydbprod'

----Restore Database
RESTORE DATABASE @newTargetDBName
FROM DISK = @restoredSourceFile
WITH MOVE @restoredSourceLogicalDataFileName TO @newTargetDataFileName,
MOVE @restoredSourceLogicalLogFileName TO @newTargetLogFileName,
MOVE @restoredSourceLogicalSysFTName TO @newTargetSysFTName
go

If you do not know the logical names of the production database you can query the .bak file.

RESTORE FILELISTONLY
FROM DISK = 'E:\ReleaseBackups\mydbprod_20091208.bak'
GO
