When restoring a backup, how do I disconnect all a

Question

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

Answer 1

You want to set your db to single user mode, do the restore, then set it back to multiuser:

ALTER DATABASE YourDB
SET SINGLE_USER WITH
ROLLBACK AFTER 60 --this will give your current connections 60 seconds to complete

--Do Actual Restore
RESTORE DATABASE YourDB
FROM DISK = 'D:\BackUp\YourBaackUpFile.bak'
WITH MOVE 'YourMDFLogicalName' TO 'D:\Data\YourMDFFile.mdf',
MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf'

/*If there is no error in statement before database will be in multiuser
mode.  If error occurs please execute following command it will convert
database in multi user.*/
ALTER DATABASE YourDB SET MULTI_USER
GO

Answer 2

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

None of these were working for me, couldn't delete or disconnect current users. Also couldn't see any active connections to the DB. Restarting SQL Server (Right click and select Restart) allowed me to do it.
