INSERT INTO EMP VALUES    (7934,'MILLER','CLERK',7782,to_date('23-1-1982','dd-mm-yyyy'),1300,NULL,10);  


CREATE TABLE BONUS

CREATE TABLE SALGRADE      ( GRADE NUMBER,      LOSAL NUMBER,      HISAL NUMBER );
INSERT INTO SALGRADE VALUES (1,700,1200);  
INSERT INTO SALGRADE VALUES (2,1201,1400); 
INSERT INTO SALGRADE VALUES (3,1401,2000);  
INSERT INTO SALGRADE VALUES (4,2001,3000); 
INSERT INTO SALGRADE VALUES (5,3001,9999);  
COMMIT;
