Question

I have an MDF and LDF file of SQL Server 2005. i attached it with SQL Server 2008 and did some change in data. now when i attached it back to sql server 2005 Express Edition it gives version error.

The database ‘E:\DB\JOBPERS.MDF’
cannot be opened because it is version
655. This server supports version 612 and earlier. A downgrade path is not
supported. Could not open new database
‘E:\DB\JOBPERS.MDF’. CREATE DATABASE
is aborted. An attempt to attach an
auto-named database for file
E:\DB\Jobpers.mdf failed. A database
with the same name exists, or
specified file cannot be opened, or it
is located on UNC share.

The database ‘ASPNETDB.MDF’ cannot be opened because it is version 655. This server
supports version 612 and earlier.

You cannot backup/restore or
detach/attach from a higher version to
a lower version.

1. Use database publishing wizard to get out the script for all objects in
   2008 db

2. Create a new empty database in your 2005 instance .
3. Execute the above generated script in your new 2005 database.
4. Move your SQL server logins/users from 2008 database to 2005 database
   using sp_help_revlogin stored
   procedure.

Thanks, Leks
