mysql2redis's Issues

LTRIM command not support?

i use this code, but list is not trimed:

SET v_redis_ret=redis_command_v2('LTRIM', 'UserReadingRecord4', 0, 4);

when i use redis_command_v2 in cursor, the data count is wrong

BEGIN
DECLARE done INT DEFAULT FALSE;
DECLARE v_id INT;
DECLARE v_ret INT;
DECLARE cur CURSOR FOR SELECT u.user_id FROM kid_users u WHERE u.latest_login_time>=DATE(DATE_ADD(NOW(),INTERVAL -1 DAY)) AND EXISTS(SELECT * FROM kid_child_info WHERE user_id=u.user_id AND gender IN(0,1)) ORDER BY u.latest_login_time DESC;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

OPEN cur;
read_loop: LOOP
	FETCH cur INTO v_id;
	IF done THEN
		LEAVE read_loop;
	END IF;

	SET v_ret=redis_command_v2('LPUSH', 'calcReadingRecommendForYou', CONCAT(v_id));
END LOOP;
CLOSE cur;

END

the openfile and the sredisContext are not release ?

when the free_resources is called,
I think you want to close the pFile and redisFree sredisContext ?

when to support more args like redis "hset" command

or is there a plan to support it?

How to check the data in Redis?

Hi,
I'm new to Redis and MySQL. Could you tell me how to check the data entered in Redis from Mysql?

lpush twice

DELIMITER $$
CREATE TRIGGER user_consult_insert_trigger AFTER INSERT ON user_consult
FOR EACH ROW BEGIN
set @id = redis_servers_set_v2("127.0.0.1", 6369);
set @ret = redis_command_v2("", 0, "lpush",
concat("user-consultation-list-", NEW.user_id),
concat(NEW.id)
);
set @ret = redis_command_v2("", 0, "lpush",
concat("consultant-consultation-list-", NEW.consultant_id),
concat(NEW.id)
);
set @ret = redis_command_v2("", 0, "set",
concat("user_consult-", NEW.id),
json_object(
NEW.id as "id",
NEW.user_id as "user_id",
NEW.consultant_id as "consultant_id",
NEW.service_id as "service_id",
NEW.service_type as "service_type",
NEW.title as "title",
NEW.content as "content",
NEW.ctime as "ctime",
NEW.reply_num as "reply_num"
)
);
END$$
DELIMITER ;

the code above is my trigger.this trigger always insert primary id into user-consultation-list* twice

SOMETHING WRONG WITH THE MAKE COMMAND

base on MySQL-server-5.6.32-1.linux_glibc2.5.i386.rpm , when I make the mysql2redis,the below message showed:
