What is wrong in my query with MySql store procedure? - mysql

Question

I am new to mysql store procedure. I want my store procedure to check date value in Field date and compare to current date. If current date is bigger than date value in table, I want to update value in field status_number to '0'.
Here is my query :
DELIMITER $$
DROP PROCEDURE IF EXISTS check_status$$
CREATE PROCEDURE check_status()
BEGIN
DECLARE dd DATE;
DECLARE bDone INT;
DECLARE Count INT;
DEClARE my_status CURSOR FOR SELECT dates FROM t_date;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;
OPEN my_status;
SET bDone = 0;
REPEAT
FETCH my_status INTO dd;
IF (dd < DATE(NOW()))
UPDATE t_date SET (status_number) VALUES (1);
END IF;
UNTIL bDone END REPEAT;
CLOSE my_status;
END$$
DELIMITER ;
Error message :
Thank for answering.

Check it. its tested on mssql. I try to convert it for mysql but not tested on mysql but i hope it will works.
DELIMITER //
CREATE PROCEDURE check_status()
BEGIN
DECLARE NOT_FOUND INT DEFAULT 0;
DECLARE v_dd DATE;
-- DECLARE #bDone INT;
-- DECLARE #Count INT;
DECLARE v_name VARCHAR(50); -- database name
DECLARE v_path VARCHAR(256); -- path for backup files
DECLARE v_fileName VARCHAR(256); -- filename for backup
DECLARE v_fileDate VARCHAR(20); -- used for file name
DECLARE db_cursor CURSOR FOR
SELECTdates INTO v_dd
FROM t_date
OPEN
DECLARE CONTINUE HANDLER FOR NOT FOUND SET NOT_FOUND = 1;db_cursor
-- SET #bDone = 0;
FETCH NEXT FROM; db_cursor INTO v_dd
WHILE NOT_FOUND = 0
DO
IF (v_dd < cast (Now() as date) )
Then
UPDATE t_date SET status_number = 1;
END IF;
FETCH NEXT FROM; db_cursor INTO v_dd
END WHILE;
CLOSE db_cursor;
END;
