Endless Looping Job!!!!

i have created a job that i have scheduled to run every 10 min everything is configured well since i have tested preety everything their is to be tested and found that it was my last step wich as a fetch in it so i imagine that this fetch is making it loop over and over again. the job goes trought all the steps and starts back at the first step and keep going like that till i disable it here is my fetch statement and if you have any clue any help would be widely apreciated.


PS: i suspected it to be that fetch statement causing the havoc ;)



DECLARE
@TransactionNb varchar(10),
@EqId varchar(10)

DECLARE TransactionNb_cursor CURSOR
FOR
SELECT TransactionNb, EqId

WHERE UpdCode = 'C'

OPEN TransactionNb_cursor

FETCH NEXT FROM TransactionNb_cursor
INTO @TransactionNb, @EqId

WHILE @@FETCH_STATUS <> -1
BEGIN
-- Vérifier s'il existe une transaction avec le UpdCode = 'C' dans EntCom
IF (SELECT UpdCode
FROM EntCom
WHERE TransactionNb = @TransactionNb and EqId = @EqId) = 'C'
BEGIN
CONTINUE
END
ELSE

END

FETCH NEXT FROM TransactionNb_cursor

CLOSE TransactionNb_cursor
DEALLOCATE TransactionNb_cursor
