Kirti,
I think, you have typo (duplicate rows), when describing data inserted into
table, considering PK on (col1, col2).
Shouldn't it be:
SQLWKS> create table test(
2> col1 varchar2(10),
3> col2 varchar2(10),
4> constraint PK_TEST primary key (col1, col2));
Statement processed.
SQLWKS>
SQLWKS> insert into test (col1, col2) values ('A', 'B');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('C', 'D');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('E', 'F');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('G', 'H');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('B', 'A');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('F', 'E');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('D', 'C');
1 row processed.
SQLWKS> insert into test (col1, col2) values ('H', 'G');
1 row processed.
SQLWKS> commit;
Statement processed.
SQLWKS>
SQLWKS> select * from test;
COL1 COL2
---------- ----------
A B
C D
E F
G H
B A
F E
D C
H G
8 rows selected.
SQLWKS> select * from test order by col1;
COL1 COL2
---------- ----------
A B
B A
C D
D C
E F
F E
G H
H G
8 rows selected.
