How to rename database without first stopping SQL instance to flush connections

Question

Is there a way to force a database into single user mode so a script can be run to rename databases? I find I have to Restart the instance of SQL (to force off any connections from a web app, etc.) and then I can run this script:

USE master go sp_dboption MDS, "single user", true go sp_dboption StagingMDS, "single user", true go sp_renamedb MDS, LastMonthMDS go sp_renamedb StagingMDS, MDS go sp_dboption LastMonthMDS, "single user", false go sp_dboption MDS, "single user", false go 

After this script runs, I can restart IIS for my web app and it can connect to the new production database.

All the above works well and we've been doing this for years but now we've upgraded to SQL 2008 and the SQL2008 instance also hosts other databases that support other web apps.

So, rather than using a Restart of the whole SQL instance to enable subsequent single-user mode on 2 databases, is there a less intrusive way of accomplishing this? Thanks.

Answer 1

This should kill any open connections to the database:

alter database mds set single_user with rollback immediate
