oracle 逗号分隔列转多行数据

TITLE 表数据如下图：

ID  NAME
1   TEST1,TEST2
2   TEST3,TEST4
3   TEST4,TEST5
4   TEST1,TEST4
5   TEST2,TEST4,TEST5

测试SQL如下：

SELECT ID, REGEXP_SUBSTR(NAME, '[^,]+', 1, LEVEL) NAME
FROM TITLE
CONNECT BY LEVEL <= REGEXP_COUNT(NAME, '[^,]+')
       AND ROWID = PRIOR ROWID
       AND PRIOR DBMS_RANDOM.VALUE IS NOT NULL
ORDER BY NAME;

测试SQL如下：

ID  NAME

1   TEST1
1   TEST2
5   TEST2
2   TEST3
4   TEST4
2   TEST4
5   TEST4
