When restoring a backup, how do I disconnect all active connections?

Question

My SQL Server 2005 doesn\'t restore a backup because of active connections. How can I force it?

Answer 1

This code worked for me, it kills all existing connections of a database. All you have to do is change the line Set @dbname = 'databaseName' so it has your database name.

Use Master
Go

Declare @dbname sysname

Set @dbname = 'databaseName'

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

after this I was able to restore it
