Question

memberStatus总是返回0.但是当我单独运行查询时，它可以正常工作。

DROP PROCEDURE IF EXISTS getMySubjectLists;

DELIMITER $$

CREATE PROCEDURE getMySubjectLists(
     IN myID    INT,        
     IN GID     INT
)
BEGIN
    DECLARE memberStatus INT DEFAULT 0;

    SELECT COALESCE(status,0) into memberStatus from member_access where group_id = GID and subject_id = 0 and topic_id = 0 and subtopic_id = 0 
        and member_id = myID;

        insert into apps_log values(0,memberStatus,GID,myID,"",now());  

END$$
DELIMITER ;

为member_access创建表格如下。该过程不仅适用于此特定表。我尝试过其他表，但它确实有效。

CREATE TABLE `member_access` (
 `seqno` int(11) NOT NULL AUTO_INCREMENT,
 `mapid` int(11) NOT NULL,
 `group_id` int(11) NOT NULL,
 `subject_id` int(11) NOT NULL,
 `topic_id` int(11) NOT NULL,
 `subtopic_id` int(11) NOT NULL,
 `member_id` int(11) NOT NULL,
 `access_code` int(11) DEFAULT '0',
 `delegate_code` int(11) DEFAULT '0',
 `specialid1` int(11) DEFAULT '0',
 `specialid2` int(11) DEFAULT '0',
 `specialid3` int(11) DEFAULT '0',
 `status` int(11) DEFAULT '0',
 `created` datetime DEFAULT NULL,
 `updated` datetime DEFAULT NULL,
 PRIMARY KEY (`seqno`),
 KEY `indx1` (`mapid`,`access_code`,`status`),
 KEY `mig1` (`mapid`,`member_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

存储过程始终返回0
