Drop all Database Connections

Although this could be a very dangerous script to run, it is very useful when you need to do some maintenance on a database and there are some rouge connections open stopping you from doing so. The script will run through all users currently connection to the specified database and kill their connection.

Use Master
Go
Declare @dbname sysname
Set @dbname = 'name of database you want to drop connections from'
Declare @spid int
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname)
While @spid Is Not Null
Begin
Execute ('Kill ' + @spid)
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname) and spid > @spid
End
