You can use below stored procedure to split string delimted by any character:

CREATE PROCEDURE `split_delimited` (
IN inputstr NVARCHAR(1000),
IN delimiter CHAR(1)
)
BEGIN
DROP TEMPORARY TABLE Items;
CREATE TEMPORARY TABLE Items(item NVARCHAR(50)); 
WHILE LOCATE(delimiter,inputstr) > 1 DO
INSERT INTO Items SELECT SUBSTRING_INDEX(inputstr,delimiter,1);
SET inputstr = REPLACE (inputstr, (SELECT LEFT(inputstr,LOCATE(delimiter,inputstr))),'');
END WHILE;
INSERT INTO Items(item) VALUES(inputstr);
select * from Items;
END

Input: 'a,b,c' Output: a b c
