sql语句出错，求大神帮忙解答

CREATE PROCEDURE test()
BEGIN

DECLARE fid int;

DECLARE days int DEFAULT 1;

DECLARE s int default 0;

DECLARE company_code VARCHAR;

DECLARE cursor_company CURSOR FOR SELECT company FROM test WHERE status = 3;

DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET a=1;

OPEN cursor_company;

FETCH cursor_company INTO company_code;
WHILE a<>1 DO

        IF company_code = 'DD' THEN

                DECLARE cursor_name CURSOR FOR SELECT id FROM test WHERE UNIX_TIMESTAMP(check_time) < UNIX_TIMESTAMP(DATE_ADD(NOW(),INTERVAL -days DAY));
                #设置一个终止标记
                DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET s=1;

                #获取游标当前指针的记录，读取一行数据并传给变量stu
                FETCH cursor_name INTO fid;
                #开始循环，判断是否游标已经到达了最后作为循环条件
                WHILE s <> 1 do

表结构

id int

check_time datetime

status int

company varchar

错误信息：

DECLARE cursor_company CURSOR FOR SELECT company FROM test WHERE status =' at line 10

看了好久，可是感觉没有错误，不知道毛病出在哪里，求大神解答

CREATE PROCEDURE test ()
BEGIN
DECLARE
fid INT;

DECLARE
days INT DEFAULT 1;

DECLARE
s INT DEFAULT 0;

DECLARE
a INT DEFAULT 0;

DECLARE
company_code VARCHAR (50);

DECLARE
cursor_company CURSOR FOR SELECT
company
FROM
test
WHERE
STATUS = 3;

DECLARE
cursor_name CURSOR FOR SELECT
id
FROM
test
WHERE
UNIX_TIMESTAMP(check_time) < UNIX_TIMESTAMP(
DATE_ADD(NOW(), INTERVAL - days DAY)
);

#设置一个终止标记
DECLARE
CONTINUE HANDLER FOR SQLSTATE '02000'
SET s = 1;

OPEN cursor_company;

FETCH cursor_company INTO company_code;

WHILE s <> 1 DO

IF company_code = 'DD' THEN

SET days = 2;

ELSEIF company_code = 'ZD' THEN

SET days = 5;

ELSEIF company_code = 'GG' THEN

SET days = '8';

END IF;

FETCH cursor_company INTO company_code;

#打开游标
OPEN cursor_name;

#获取游标当前指针的记录，读取一行数据并传给变量stu
FETCH cursor_name INTO fid;

#开始循环，判断是否游标已经到达了最后作为循环条件
WHILE s <> 1 DO
UPDATE test
SET STATUS = 8
WHERE
id = fid;
set s = 0;
#读取下一行的数据

FETCH cursor_name INTO fid;

END
WHILE;

#关闭游标

CLOSE cursor_name;

#语句执行结束

END
WHILE;

CLOSE cursor_company;

END

给你格式化了一下
不然有点乱乱
DECLARE
CONTINUE HANDLER FOR SQLSTATE '02000'
这个只定义一个

想实现的功能是：

根据表中company 的字段去判断，不同的company， 赋予days变量不同天数，然后让当前时间-days跟checktime去做比较，最后执行update语句。。。

其实就是更改status状态，来实现 链接失效 这个功能，求大神们指导，刚入行的新人。轻喷。。

可以啦，谢谢 = =
