Anyone know the generic practices transfer the database to SQL Server 2008 from SQL Server 2008 Express (I'm not sure it is r2), when I try to attach the .mdf file from Express, there is an error message.
the database cannot be opened because it is version 661. This server supports version 655 and earlier. A downgrade path is not
supported.
Well, the message is clear: the file you're trying to attach from Express is from a newer version of SQL Server
So it appears that you indeed have SQL Server 2008 R2 Express, and you cannot attach this to a SQL Server 2008 instance. There's no way, no hack, no workaround, no trick, or no third-party tool to achieve this - it just cannot be done - period.
So you either need to upgrade your main instance to SQL Server 2008 R2, too - or you need to find another way (like scripting out the structure and/or data into .SQL files) to move your changes from one instance to the other - or use a third-party tool like Red-Gate SQL Compare to synchronize the changes between the two instances.

I have .mdf files created using SQL SERVER management studio in another computer and wish to attach the same to SQL SERVER 2008 EXPRESS in another computer. How should I do so?
I tried this method :How to: Attach a Database File to SQL Server Express
but then it shows an error that the database cannot be created due to compatibility issues.
Msg 948: The database xyz cannot be opened because it is version 706.
This server supports version 655 and earlier. A downward path is not
supported..
....
This basically means your SQL versions don't match. For example, if you backup a database on SQL 2012, you can't restore it to 2008. In your case Version 706 is a database file from Sql Server 2012 and Version 663 is a database file from Sql Server 2008R2 (with some SP).
You can either install SQL Express 2012 to attach the MDF, or if you can't do that, you would have to script out your schema and data and create the DB from scratch.. Unfortunately there's no way to 'downgrade' and MDF back to an older version of SQL.
The message is very clear:
The database MDF file is version 706. Your server understands version 655 . Which means, despite to your claim to the contrary, that you are connected to a SQL Server 2008.
Install a SQL Server 2012, connect to it, and attach your database.
Please pay attention during the installation process to the instance name you choose and make sure you connect to that instance.
You can also check now what instances you have installed, look at what services you have on your system.
SELECT ##VERSION AS 'SQL Server Version'
Since we need to move around our database a lot (like update it with new Rows which are generated by code and then update it prod db and reverse process). SQL Server CE, being a file based system was very helpful.
We would like to upgrade to use SQL Server Local Db but at the same time, it has limitations of use with IIS (though possible with AttacheDbFile). In this regard, since LocalDb is more or less a version of SQL Server Express, would it be possible to use our SQL Server LocalDB .mdf in our development environment and then copy them in prod but use by attaching to a SQL Server Express instance?
If yes, what additional thing, we need to do make it possible?
Also, we would like the reverse process to be worked out as well, mean detach the .mdf file and use it as LocalDb in development environment. I have read the great blog articles of
Krzysztof Kozielczyk also but not have experimented much with LocalDb.
LocalDB IS SQL Server Express (introduced with SQL Server 2012 Express), and the .mdf file is identical between LocalDB and SQL Server Express (and even a "full" SQL Server edition like Web, Standard or Enterprise Edition).
The only caveat is: you need to be using the same versions of those databases, since the file format is only identical amongst same versions, and can only be used amongst the same versions (e.g. 2012) - or it can be "upgraded" to the next newer version (e.g. you could move a database from LocalDB 2012 to a SQL Server 2014 Express once it's released) - but you can never go back down to an earlier version (you cannot take a LocalDB 2012 .mdf database file and attach it to a SQL Server 2008 version).
what update i need to install for version 655 in vs studio 2010 for the sql server.
Can anyone tell me what i need on my computer when creating a database using sql on vs studio 2010? I need to use version 655 cos thats the version being used on Uni Computers
SQL Server 2008 (655) and SQL Server 2008 R2 (661) are not the same thing (though it is a common misconception - a lot of people think they're the same because Microsoft made a terrible, terrible, terrible naming decision, making 2008 R2 sound like a service pack).
You can't attach/restore a 2008 R2 database to a 2008 instance, period. Though there are several workarounds (that also apply for attaching 2012 -> 2008, 2008 -> 2005, 2008 R2 -> 2005, etc). You can either upgrade the engine you're trying to connect to up to 2008 R2, or you can extract the schema / data from the database using generate scripts wizard, import/export data wizard, SSIS, or 3rd party tools like Red Gate SQL Compare (for a full list of alternatives see this blog post).
This comes up extremely often, did you search for "sql server version 661 655"? I came up with a whole bunch of hits using this search term and some slight variations, all on this site and dba.SE:

If you are developing .NET based apps in visual studio 2010, then they will typically support all versions of Microsoft SQL Server. That does not mean you install SQL server INSIDE of visual studio, just that you can connect to a SQL Server instance running somewhere.
If you are asking "Where can I get a copy of SQL Server that my university is using?", that depends. For development, you can use a SQL Express installation on your local machine that matches the major release of SQL (2005, 2008, 2008R2, 2012), or you can request the university (or someone else) grant you access to an existing SQL instance.
My team needs to update an automated content process running over SQL Server 2008 servers to include the content of a SQL Server 2008 R2 database delivered by a third-party vendor.
The request to third-party to deliver us on SQL Server 2008 is NOT an option.
My common sense indicates there is no way to downgrade from 2k8 R2 to 2k8 as in most of the software products I know. However, I'm wondering if I would be able to do something like this in a script:
Restore SQL Server 2008 R2 .bak file onto our SQL Server 2008 R2 instance
Update compatiblity level to SQL Server 2008 (100). Here is the bug in my plan: I've not found any compatiblity level distinctions between 2008 versions in internet. Any clue on this?
Backup the database.
Restore the database in SQL Server 2008
There may be some other ideas you may want to share with me.
Just recall there should not be manual intervention on this database conversion since this operation needs to be incorporated to an automated process.
Any help/suggestions/comments will be welcome!
No, you cannot restore a database backwards, regardless of compatibility level. Compatibility level affects certain database engine behaviors, but does not downgrade the database version. You will never be able to restore onto 2008 a database that ever existed in a 2008 R2 instance.
For workarounds, you can:
restore the database on R2, then use the import/export data wizard (or a third party tool) to transfer schema / data to the 2008 instance (and you should be able to automate this to some extent, e.g. Red-Gate's tools have command-line interfaces)
upgrade your 2008 servers to 2008 R2 or 2012
push back on the vendor
By design, you can only restore a DB backup to the same or newer version of SQL Server. A backup created with SQL Server 2008 R2 can only be restored with SQL Server 2008 R2 or SQL Server 2012. This is regardless of the compatibility level of the database. It's a limitation of the backup and restore procedures. This has been a limitation since prior to SQL Server 2000 (i.e., every version I've ever used).
Maybe you can script out the creation of new database, instead of backing up and restoring you basically just do a data dump with script.
Try looking at this How can I get a SQL dump of a SQL Server 2008 database?
I have SQL Server 2012 and I'm trying to attach a db which was previously used with SQL Server 2012, surprisingly I'm getting the following error:
The database 'DatabaseName' cannot be opened because it is version
706. This server supports version 622 and earlier. A downgrade path is not supported.
I don't really understand how this could happen since like I said it was used with same 2012 version. What am I doing wrong? How can I make it work? Please explain in detail how this can be resolved.
Thank you!!
The error sounds like the server you are trying to attach the database to is not SQL Server 2012. This may be the version of Management Studio / Management Studio Express you're using, but I suspect SELECT ##VERSION; will tell you something different. It may just be a connection string mixup if you have multiple instances of SQL Server installed, otherwise you should download and install SQL Server 2012 Express from here.
#source
It sounds like you had the following configuration and source databases:
SQL Server 2008 SP3 (ver 10.0...) - database engine
SQL Server Management Studio 2012 (ver 11.0...) - management tools
a database that was created with SQL Server 2012 (version 706)
As mentioned you could install SSMS for SQL Server 2008 (after you uninstall SSMS for SQL Server 2012). Then you would have to script your database for that version and re-run the script via 'Tasks>Script...', remembering to set the target server version as shown below.
After scripting you can then use the import/export wizard to export and then inport the data into the new (downgraded database), assuming the database had no 2012-only datatypes (such as sequences).
Another consideration is database compatibility level as shown below. You can have a SQL Server 2012 instance which hosts databases with various compatibility levels.
Using SELECT ##VERSION works very well for me. Your Database Engine is connected to a 2008 DB which certainly doesn't allow you to attach. Once I change my Database Engine to connect to 2012 DB, it works for me.
Check your Database Engine connection. You can be working on 2012 Management Studio yet connecting to 2008 DB. This is what happened to me and I have solved it use SELECT ##VERSION.
