    INSERT INTO STAFF VALUES (null,'Jaime Stark',to_date('29/04/1951','dd/mm/YYYY'),'607 4432-1059','Donec.fringilla.Donec@necurnaet.ca','P.O. Box 891, 5837 Enim Avenue',to_date('16/06/2010','dd/mm/YYYY'),NULL,41695,NULL,1,1);

    or 

    INSERT INTO STAFF (EMP_NAME,EMP_DOB,EMP_TEL,EMP_EMAIL,EMP_ADDR,EMP_HIREDATE,EMP_ENDDATE,EMP_SALARY,EMP_SUPERVISOR,JOB_CODE,BRA_CODE)
VALUES ('Jaime Stark',to_date('29/04/1951','dd/mm/YYYY'),'607 4432-1059','Donec.fringilla.Donec@necurnaet.ca','P.O. Box 891, 5837 Enim Avenue',to_date('16/06/2010','dd/mm/YYYY'),NULL,41695,NULL,1,1);
