Oracle SQL:

SELECT  REPLACE(SUBSTR(r_str, 1, INSTR(r_str, ',', 1, 1) - 1), ' ') AS r_substr_1
,       REPLACE(SUBSTR(r_str, INSTR(r_str, ',', 1, 1) + 1, INSTR(r_str, ',', 1, 2) - INSTR(r_str, ',', 1, 1) - 1), ' ') AS r_substr_2
,       REPLACE(SUBSTR(r_str, INSTR(r_str, ',', 1, 2) + 1, INSTR(r_str, ',', 1, 3) - INSTR(r_str, ',', 1, 2) - 1), ' ') AS r_substr_3
,       REPLACE(SUBSTR(r_str, INSTR(r_str, ',', 1, 3) + 1, INSTR(r_str, ',', 1, 4) - INSTR(r_str, ',', 1, 3) - 1), ' ') AS r_substr_4
,       REPLACE(SUBSTR(r_str, INSTR(r_str, ',', 1, 4) + 1), ' ')    AS r_substr_5
FROM
(
        SELECT  'Apples, oranges, pears,berries, melons' r_str FROM DUAL
);

Result: Apples  oranges pears   berries melons
