.mdf is too new (661) my database supports version 655

Question

I am using SQL Server 2008 express and i want to import .mdf and i get this error: .mdf version is 661, your db supports the version 655

Which version is 661 and how to import it in sql Server 2008.

Answer 1

Install SQL Server 2008 EXPRESS R2. There is a bug in the Web Platform Installer and it still thinks EXPRESS R1 is the latest version.

Answer 2

You will need to apply a service pack. Check Microsoft Update.

Answer 3

Version 661 sounds like the format used by server 2008 R2 so it looks like someone has installed the beta and then attached your DB to it.

Answer 4

Express 2008 - like without any service pack? Try getting your hands on the latest express version (they did not get service packs, but new installers) and install that. Chance we talk about 2008 R2 express, which should run around somewhere as beta?

Answer 5

You have probably selected the instance name on the dialog box that comes when you try to add a connection from the server explorer in VS 2010. Try giving only the server name and it should work.
