Tohoro query = new Tohoro(); query.setReservationListNo(tohoro.getReservationListNo()); List<Tohoro> list= tohoroMapper.selectTohoroList(query); boolean check=true; for (Tohoro item:list){ if("0".equals(item.getCheckStatus())){ check=false; } } if(check){ ReservationList checkItem= reservationListMapper.selectReservationListListByReservationListNo(tohoro.getReservationListNo()); if(checkItem!=null){ ReservationList update = new ReservationList(); update.setTicketStatus("1"); update.setId(checkItem.getId()); reservationListMapper.updateReservationList(update); } }请根据这段代码写一个存储过程

根据这段Java代码,可以编写一个存储过程来更新ReservationList表中的数据。以下是一个示例:
```
DELIMITER //
CREATE PROCEDURE update_reservation_list(IN reservation_list_no INT)
BEGIN
DECLARE check_status VARCHAR(255);
DECLARE check_item_id INT;
DECLARE done INT DEFAULT FALSE;
DECLARE cur CURSOR FOR SELECT check_status, check_item_id FROM (
SELECT
(CASE WHEN check_status = '0' THEN 'false' ELSE 'true' END) AS check_status,
reservation_list.id AS check_item_id
FROM tohoro
JOIN reservation_list ON tohoro.reservation_list_no = reservation_list.reservation_list_no
WHERE tohoro.reservation_list_no = reservation_list_no
) AS subquery;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
OPEN cur;
read_loop: LOOP
FETCH cur INTO check_status, check_item_id;
IF done THEN
LEAVE read_loop;
END IF;
IF check_status = 'false' THEN
-- 如果存在check_status为0的记录,则直接退出循环
LEAVE read_loop;
END IF;
END LOOP;
CLOSE cur;
IF check_status = 'true' THEN
-- 如果所有记录的check_status都为1,则更新ReservationList表
UPDATE reservation_list SET ticket_status = '1' WHERE id = check_item_id;
END IF;
END //
DELIMITER ;
```
这个存储过程接受一个输入参数reservation_list_no,它使用游标来检索与该参数匹配的Tohoro和ReservationList表中的数据,并检查所有记录的check_status是否都为1。如果是,则更新ReservationList表中的相应记录的ticket_status列为1。
要使用此存储过程,您可以使用以下语句调用它:
```
CALL update_reservation_list(123);
```
其中,123是您要更新的ReservationList记录的reservation_list_no值。请注意,在实际使用中,您需要根据您的表结构和需要进行适当的修改。
