Hi,
A quick pl/sql question for oracle 9i. I have these two pl/sql blocks below,
does oracle treat them same internally when inside the loop?
Would "method 2" be better, in terms of performance?
Thanks.

- method 1:
DECLARE
CURSOR c1 IS
SELECT ID, s1
FROM t1
WHERE s1 = 'abc';
FOR UPDATE;
BEGIN
FOR x IN c1 LOOP
UPDATE t1
SET StateID = 'NEW',
LASTMODIFIEDDT = sysdate
WHERE s1 = x.s1;
END LOOP;
END;
- method 2:
DECLARE
CURSOR c1 IS
SELECT ID, s1
FROM t1
WHERE s1 = 'abc';
FOR UPDATE;
BEGIN
FOR x IN c1 LOOP
UPDATE t1
SET StateID = 'NEW',
LASTMODIFIEDDT = sysdate
where current of c1;
END LOOP;
END;
