SQL Server: Kill process using stored procedure

Question

I want to change the following, since it does not seem to kill processes - I think it should disconnect users (is it the same?). I want to be able to kill the whole process for a specific database - how can I change below:

create procedure [dbo].[sp_killusers](@database varchar(30))
as
----------------------------------------------------
-- * Created By David Wiseman, Updated 19/11/2006
-- * http://www.wisesoft.co.uk
-- * This procedure takes the name of a database as input
-- * and uses the kill statment to disconnect them from
-- * the database.
-- * PLEASE USE WITH CAUTION!!
-- * Usage:
-- * exec sp_killusers 'databasename'
----------------------------------------------------
set nocount on
declare @spid int
declare @killstatement nvarchar(10)

-- Declare a cursor to select the users connected to the specified database
declare c1 cursor for select request_session_id
                                from sys.dm_tran_locks
                                    where resource_type='DATABASE'
                                    AND DB_NAME(resource_database_id) = @database
open c1
fetch next from c1 into @spid
-- for each spid...
while @@FETCH_STATUS = 0
begin
      -- Don't kill the connection of the user executing this statement
      IF @@SPID <> @spid
      begin
            -- Construct dynamic sql to kill spid
            set @killstatement = 'KILL ' + cast(@spid as varchar(3))
            exec sp_executesql @killstatement
            -- Print killed spid
            print @spid
      end
      fetch next from c1 into @spid
end
-- Clean up
close c1
deallocate c1

Update

The above does not work, that is, it does not kill the process.

He does not kill the process. I look at the activity monitor and it shows that the process is ongoing, and I can see my request, still working in the request window. When I "kill 53", requests stop in the request window and the process has left the monitor! So what kills work, but not this procedure, why?

SET @killstatement = 'KILL ' + cast(@spid as varchar(3)) 
EXEC (@killstatement)

Answer 5

, , , ( SQL 2005).

• .
• , , spid 51. ( , , , .)
• , , . .
• . - , , .

Starting SQL Profiler and tracking logins and logging when starting this process can be detected, especially for problems with the connection pool.

Answer 6

This works for me in SQLServer 2000

DECLARE @DbName VARCHAR(100)
DECLARE @SPID INT
DECLARE @TranUOW UNIQUEIDENTIFIER
DECLARE @KillStmt NVARCHAR(100)

SET @DbName = 'MyDatabase'

-----------------------------------
-- Kill distributed transactions

DECLARE dist CURSOR FOR
    SELECT DISTINCT req_transactionUOW
        FROM master..syslockinfo
        WHERE db_name(rsc_dbid) = @DbName
              AND req_transactionUOW <> '00000000-0000-0000-0000-000000000000'

OPEN dist

FETCH NEXT FROM dist INTO @TranUOW

WHILE @@FETCH_STATUS = 0
BEGIN
    SET @KillStmt = 'kill ''' + CAST(@TranUOW AS VARCHAR(50)) + ''''

    PRINT @KillStmt
    EXECUTE(@KillStmt)

    FETCH NEXT FROM dist INTO @TranUOW
END

CLOSE dist
DEALLOCATE dist

-----------------------------------
-- Kill user connections

DECLARE cur CURSOR FOR
    SELECT spid
        FROM master..sysprocesses
        WHERE db_name(dbid) = @DbName
              AND spid > 50

OPEN cur

FETCH NEXT FROM cur INTO @SPID

WHILE @@FETCH_STATUS = 0
BEGIN
    SET @KillStmt = 'kill ' + CAST(@SPID AS VARCHAR(10))

    PRINT @KillStmt
    EXECUTE(@KillStmt)

    FETCH NEXT FROM cur INTO @SPID
END

CLOSE cur
DEALLOCATE cur
