[T-SQL] Kill All Process in Database

I was just going trough one query and find out that it was giving one error , but its really useful script for killing all process. One thing just be sure that you are not killing the process from the db instance from where you are running the query.

CREATE TABLE #TmpWho
(spid INT, ecid INT, status VARCHAR(150), loginame VARCHAR(150),
hostname VARCHAR(150), blk INT, dbname VARCHAR(150), cmd VARCHAR(150), rquest_id INT)
INSERT INTO #TmpWho
EXEC sp_who
DECLARE @spid INT
DECLARE @tString VARCHAR(15)
DECLARE @getspid CURSOR
SET @getspid = CURSOR FOR
SELECT spid
FROM #TmpWho
WHERE dbname = 'mydb'OPEN @getspid
FETCH NEXT FROM @getspid INTO @spid
WHILE @@FETCH_STATUS = 0
BEGIN
SET @tString = 'KILL ' + CAST(@spid AS VARCHAR(5))
EXEC(@tString)
FETCH NEXT FROM @getspid INTO @spid
END
CLOSE @getspid
DEALLOCATE @getspid
DROP TABLE #TmpWho
GO
