How to resolve ORA-00001 Error in SQL Insert?

Question

Hi all, I need your appreciated help.
I make a plsql procedure that is inserting a row according cursor value, I'm having oracle error ORA-00001: unique constraint (constraint_name) violated.
You may see this message if a duplicate entry exists at a different level: in RDBMS MySQL I have the syntax IGNORE to resolve this duplication error... and in Oracle ?
Thanks for your time and hints.

SQL = "INSERT INTO COUNTRIES(COUNTRY_ID,COUNTRY_NAME,REGION_ID) SELECT 'BZ','BLZ',3 FROM DUAL WHERE NOT EXISTS(SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID = 'BZ')"There is a good chance table COUNTRIES also has unique key/index on COUNTRY_NAME. If so use:
SQL = "INSERT INTO COUNTRIES(COUNTRY_ID,COUNTRY_NAME,REGION_ID) SELECT 'BZ','BLZ',3 FROM DUAL WHERE NOT EXISTS(SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID = 'BZ' OR COUNTRY_NAME = 'BLZ')"SY.
