This snippet comes from the Oracle console:
(table name is "a" not "test" / messages are in german)

SQL> show autocommit;
autocommit OFF
SQL> select * from a;

A
----------
1

SQL> commit;

Transaktion mit COMMIT abgeschlossen.

SQL> insert into a values (2);

1 Zeile wurde erstellt.

SQL> insert into a values (3);

1 Zeile wurde erstellt.

SQL> insert into a values (1);
insert into a values (1)
*
FEHLER in Zeile 1:
ORA-00001: Verstoß gegen Eindeutigkeit, Regel (KLAX.SYS_C001753)

SQL> insert into a values (4);

1 Zeile wurde erstellt.

SQL> commit;

Transaktion mit COMMIT abgeschlossen.

SQL> select * from a;

A
