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

Answer 1

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?
