CREATE TABLE CFL (q_id Number(18),per_id number(18),PERIOD VARCHAR2(15 CHAR), AMOUNT NUMBER);
INSERT INTO CFL VALUES (11, 1, 'JAN-10', 10);
INSERT INTO CFL VALUES (21, 1, 'FEB-10', 20);
INSERT INTO CFL VALUES (31, 1, 'MAR-10', 10);
and so on (12 records for a year with same quota_id, e.g. here it is 1)
INSERT INTO CFL VALUES (121, 1, 'DEC-10', 10);
INSERT INTO CFL VALUES (12, 2, 'JAN-10', 10);
INSERT INTO CFL VALUES (22, 2, 'FEB-10', 20);
INSERT INTO CFL VALUES (32, 2, 'MAR-10', 10);
and so on (12 records for a year with same per_id, e.g. here it is 1)
INSERT INTO CFL VALUES (42, 2, 'DEC-10', 10);
COMMIT;
Also this column values period is dynamic.. it can be for any year.
The select will return values like
Select per_id, PERIOD, amount from cfl
where quota_id = 1
Basically 12 rows will be the output:
per_id period amount
1 JAN-10 10
1 FEB-10 20
1 MAR-10 10
..............and so on
1 DEC-10 10
The result output should be:
Per_id JAN-10 FEB-10 MAR-10.............DEC-10
1 10 20 10................10

I am sorry about that..
I had given a sample data..
CREATE TABLE CFL (q_id Number(18),per_id number(18),PERIOD VARCHAR2(15 CHAR), AMOUNT NUMBER);
INSERT INTO CFL VALUES (11, 1, 'JAN-10', 10);
INSERT INTO CFL VALUES (21, 1, 'FEB-10', 20);
INSERT INTO CFL VALUES (31, 1, 'MAR-10', 10);
INSERT INTO CFL VALUES (12, 2, 'JAN-10', 10);
INSERT INTO CFL VALUES (22, 2, 'FEB-10', 20);
INSERT INTO CFL VALUES (32, 2, 'MAR-10', 10);
COMMIT;
Select per_id, PERIOD, amount from cfl
where per_id = 1
/*Output will be:
per_id PERIOD amount
---------------------------------
1 JAN-10 10
1 FEB-10 20
1 MAR-10 10
The expected output that we want is:
per_id JAN-10 FEB-10 MAR-10
--------------------------------------
1 10 20 10
Also, period is dynamic. The values are not fixed.
