如何从 MDF 数据库中删除一个主文件？

Question

One of the MDF files for a SQL Server database inadvertently ended up with 2 primary files (1 database is pointing to 2 different MDF files). How can I remove the reference to one of these files, so that I may reattach my database and bring it online?

Answer 1

I realized that we had Sandbox environments cloned from all of our production stuff that was about 1 month old. Luckily, that particular database is not used very often and had not been written to in over a month. So I was able to capture a BAK file from the Sandbox environment, and restore the database to our production environment. Worked like a charm!
