    Nice script!

    RequestID added to #tmpUsers for SQL2005


    Alter PROCEDURE KillALLUsers @dbname varchar(50) as


    DECLARE @strSQL varchar(255)

    PRINT 'Killing Users'

    PRINT '-----------------'

    CREATE table #tmpUsers(

    spid int,

    eid int,

    status varchar(30),

    loginname varchar(50),

    hostname varchar(50),

    blk int,

    dbname varchar(50),

    cmd varchar(30),

    request_id int)


    DECLARE LoginCursor CURSOR


    FOR SELECT spid, dbname FROM #tmpUsers WHERE dbname = @dbname

    DECLARE @spid varchar(10)

    DECLARE @dbname2 varchar(40)

    OPEN LoginCursor

    FETCH NEXT FROM LoginCursor INTO @spid, @dbname2

    WHILE (@@fetch_status <> -1)


    IF (@@fetch_status <> -2)


    PRINT 'Killing ' + @spid

    SET @strSQL = 'KILL ' + @spid

    EXEC (@strSQL)


    FETCH NEXT FROM LoginCursor INTO @spid, @dbname2


    CLOSE LoginCursor

    DEALLOCATE LoginCursor

    DROP table #tmpUsers

    This is a much simpler way to get everyone out of the database:

    -- Get rid of all DB users

    use master

    alter database MyDatabase set offline with rollback immediate

    -- Bring DB back online in single user mode, and connect to DB

    alter database MyDatabase set online, single_user with rollback immediate

    use MyDatabase

    -- do stuff --

    -- Return DB to multi user mode

    use master

    alter database MyDatabase set multi_user with rollback immediate

    Very handy sp, i modified it so it validates the database name parameter against a whitelist of DBs we want to allow this to run against.

    Always use whitelists. Blacklists eventually result in something happening accidentally because you forgot to maintain the list.

    ¿And if the connection to @dbname comes from a view of another database on the same server?

    FOR SELECT spid, dbname FROM #tmpUsers WHERE dbname = @dbname

    ¡¡appear only direct connections!! :doze:

    the connection to the VIEW will return the database to which it belongs , not to the database where are accessing
