Oracle: Comma Separated String To Rows

One simple way for single string
with t as
(select '01,05,10,15,20,25,30,35,50,75,23,03,04,00,00,00,00,00' txt from dual)
select regexp_substr ( txt, '[^,]+', 1, level) data from t CONNECT BY level <= length (txt) - length (replace (txt, ',')) + 1


Another Example
Lets say '3625,3071,1312,1113' is stored as a comma separated string,and we want to get the Employeenames from employee table of these ids.

SELECT EMPLOYEENAME  FROM
(
    SELECT
        TRIM(SUBSTR(MYTEXT, INSTR (MYTEXT, ',', 1, level) + 1, INSTR (MYTEXT, ',', 1, level+1) - INSTR (MYTEXT, ',', 1, level) -1 )) AS MYVALUES
    FROM
    (
        SELECT ',' || '3625,3071,1312,1113' ||',' AS MYTEXT FROM dual
    )
    CONNECT BY
        level <= LENGTH(MYTEXT)-LENGTH(REPLACE(MYTEXT,',',''))-1
)A, EMPLOYEE
WHERE MYVALUES=EMPLOYEEID
