Ja, Sie brauchen eine Schleife, in der Sie substring_index() verwenden können, um die Werte innerhalb der Liste zu erhalten. Die Lösung basiert auf den Antworten von dieses SO-Thema :

CREATE PROCEDURE insert_group_alert(
IN _some_data_a VARCHAR(255),
IN _data_list_b TEXT,

DECLARE strLen INT DEFAULT 0;
DECLARE SubStrLen INT DEFAULT 0;
DECLARE EXIT HANDLER FOR SQLEXCEPTION

ROLLBACK;
END;
START TRANSACTION;
INSERT INTO TableA (
some_data,
counter
)
VALUES (
_some_data_a,
1
) -- you do not really need this, since you do not provide an id
ON DUPLICATE KEY UPDATE
counter = counter + 1;
SELECT last_insert_id()
INTO @newId;
do_this:
LOOP
SET strLen = CHAR_LENGTH(_data_list_b);
INSERT INTO TableB (table_a_id, some_data) VALUES(@newId,SUBSTRING_INDEX(_data_list_b, ',', 1));
SET SubStrLen = CHAR_LENGTH(SUBSTRING_INDEX(_data_list_b, ',', 1))+2;
SET _data_list_b = MID(_data_list_b, SubStrLen, strLen); --cut the 1st list item out
IF _data_list_b = '' THEN
LEAVE do_this;
END IF;
END LOOP do_this;
COMMIT;
