SQL Cursor syntax error - mysql

Question

I have been breaking my head over this problem. Could not find any answer yet on SO, so I would be greatful if anyone could help me out!
The following query results in a suntax error. Any clue what's wrong?
BEGIN
DECLARE cur CURSOR FOR
SELECT * FROM objects
WHERE present_in_last_scrape = FALSE;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
OPEN cur;
DECLARE done INT DEFAULT 0;
read_loop: LOOP
FETCH cur INTO record;
IF done THEN
LEAVE read_loop;
END IF;
UPDATE lifetimes SET end_time=extract(epoch from now()) WHERE object_id=record.object_id AND end_time IS NULL;
END LOOP;
CLOSE cur;
END
The syntax error:
SQL Error [1064] [42000]: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DECLARE cur CURSOR FOR
SELECT * FROM objects
WHERE present_in_last_scrap' at line 2

Thank you all for your help! the epoch stuff is indeed postgresql, have changed that. #solarflare was right with the create_procedure remark, that did the trick eventually!
CREATE PROCEDURE set_end_time (out done int)
BEGIN
DECLARE cur CURSOR FOR
SELECT * FROM objects
WHERE present_in_last_scrape = FALSE;
OPEN cur;
LOOP
UPDATE lifetimes SET end_time=UNIX_TIMESTAMP(NOW()) WHERE hemnet_id=cur.hemnet_id AND end_time IS NULL;
END LOOP;
CLOSE cur;
END
