for this solution, you must create a table with the name split_table, it can have a id(autoincrement) if you need it and must have a column where to store the value (I call it valor)

DELIMITER $$

USE `dbaname`$$

DROP PROCEDURE IF EXISTS `Split`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `Split`(
    IN cadena VARCHAR(8000),
    IN delimitador VARCHAR(10)
    )
BEGIN

    TRUNCATE split_table;

    SET @posicion = 1;
    SET @ldel = LENGTH(delimitador);     
    SET @valor = SUBSTRING_INDEX(cadena, delimitador, 1);

    WHILE @valor <> '' AND @posicion > 0 DO

        SET @valor = SUBSTRING_INDEX(cadena, delimitador, 1);

        INSERT INTO split_table(valor) VALUES (@valor);

        SET @posicion = POSITION(delimitador IN cadena);
        SET @largo = LENGTH(cadena);

        IF @largo >= @posicion THEN
            SET cadena = SUBSTR(cadena, @posicion + @ldel, @largo - @posicion);
            SET @valor = SUBSTRING_INDEX(cadena, delimitador, 1);
        ELSE
            SET @posicion = 0;
        END IF;

    END WHILE;

    END$$
