How to "flatten" the structure with the TABLE expression - sql

Question

I have a VARRAYS TYPE wanted to "flatten" the structure with the TABLE expression.
The example data
CREATE OR REPLACE TYPE ARIS.NUMBER_VARRAY_5 AS VARRAY (5) OF NUMBER NOT NULL;
CREATE TABLE ARIS.TEST_2
(
DATE_START DATE,
DATE_END DATE,
O3 ARIS.NUMBER_VARRAY_5,
CATEGORY NUMBER
)
SET DEFINE OFF;
Insert into TEST_2
(DATE_START, DATE_END, O3, CATEGORY)
Values
(TO_DATE('01/01/2005 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('01/05/2005 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), NUMBER_VARRAY_5(281.25,-9999,291.5,310.5,298.75), NULL);
Insert into TEST_2
(DATE_START, DATE_END, O3, CATEGORY)
Values
(TO_DATE('01/02/2005 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('01/06/2005 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), NUMBER_VARRAY_5(-9999,291.5,310.5,298.75,300.75), NULL);
COMMIT;
using the SQL statement
select O3.* from test_2 t, table(t.o3) O3
I can get the result
COLUMN_VALUE
281.25
-9999
291.5
310.5
298.75
-9999
291.5
310.5
298.75
300.75
The question is how I get the results like
DATE_START DATE_END 03.VALUE1 03.VALUE2 03.VALUE3 03.VALUE4 03.VALUE5
01/01/2005 01/05/2005 281.25 -9999 291.5 310.5 298.75
01/02/2005 01/06/2005 -9999 291.5 310.5 298.75 300.75

Try This,
SELECT
*
FROM
(
select
t.Date_start,
t.Date_end,
row_number() OVER ( PARTITION BY DATE_START, DATE_END
ORDER BY
ROWNUM) rn,
O3.*
from
test_2 t,
table(t.o3) O3
)
PIVOT ( MAX(column_value) FOR rn in
(
1 as "03.VALUE1",
2 as "03.VALUE2",
3 as "03.VALUE3",
4 as "03.VALUE4",
5 as "03.VALUE5"
)
) ;
