I'm triyng to unpivot multiple columns in my dataset. Here's what my data look like.
CREATE TABLE T5 (idnum NUMBER,f1 NUMBER(10,5),f2 NUMBER(10,5),f3 NUMBER(10,5)
,e1 NUMBER(10,5),e2 NUMBER(10,5)
,h1 NUMBER(10,5),h2 NUMBER(10,5));
INSERT INTO T5 (IDNUM,F1,F2,F3,E1,E2,H1,H2)
VALUES (1,'10.2004','5.009','7.330','9.008','8.003','.99383','1.43243');
INSERT INTO T5 (IDNUM,F1,F2,F3,E1,E2,H1,H2
VALUES (2,'4.2004','6.009','9.330','4.7008','4.60333','1.993','3.3243');
INSERT INTO T5 (IDNUM,F1,F2,F3,E1,E2,H1,H2)
VALUES (3,'10.2040','52.6009','67.330','9.5008','8.003','.99383','1.43243');
INSERT INTO T5 (IDNUM,F1,F2,F3,E1,E2,H1,H2)
VALUES (4,'9.20704','45.009','17.330','29.008','5.003','3.9583','1.243');
COMMIT;
select * from t5;
IDNUM F1 F2 F3 E1 E2 H1 H2
1 10.2004 5.009 7.33 9.008 8.003 0.99383 1.43243
2 4.2004 6.009 9.33 4.7008 4.60333 1.993 3.3243
3 10.204 52.6009 67.33 9.5008 8.003 0.99383 1.43243
4 9.20704 45.009 17.33 29.008 5.003 3.9583 1.243
I'm unpivoting like so...
select *
from (select IDNUM,F1,F2,F3,E1,E2,H1,H2,
null as E3,null as H3
from T5)
UnPivot((F,E,H) for sk in ((F1,E1,H1) as 1,
(F2,E2,H2) as 2,
(F3,E3,H3) as 3))
order by IDNUM,SK;
IDNUM SK F E H
----- -- ------- ------- -------
1 1 10.2004 9.008 .99383
1 2 5.009 8.003 1.43243
1 3 7.33 null null
2 1 4.2004 4.7008 1.993
2 2 6.009 4.60333 3.3243
2 3 9.33 null null
3 1 10.204 9.5008 .99383
3 2 52.6009 8.003 1.43243
3 3 67.33 null null
4 1 9.20704 29.008 3.9583
4 2 45.009 5.003 1.243
4 3 17.33 null null
But what I really need is as follows...
IDNUM SK F E H F_COL_NAME
----- -- ------- ------- ------- ----------
1 1 10.2004 9.008 .99383 F1
1 2 5.009 8.003 1.43243 F2
1 3 7.33 null null F3
2 1 4.2004 4.7008 1.993 F1
2 2 6.009 4.60333 3.3243 F2
2 3 9.33 null null F3
3 1 10.204 9.5008 .99383 F1
3 2 52.6009 8.003 1.43243 F2
3 3 67.33 null null F3
4 1 9.20704 29.008 3.9583 F1
4 2 45.009 5.003 1.243 F2
4 3 17.33 null null F3
How can I do this?
Just select idnum, sk, f, e, h, 'F'||SK as col_name ... You need to specify all columns instead of an asterix.
