Need help with these portions of code:

REM insert data into the CLASS table (first record given)

INSERT INTO CLASS VALUES(10012,'ACCT-211',1,'MWF 8:00-8:50 a.m.','BUS311');

REM insert data into the STUDENT table (first record given)

INSERT INTO STUDENT VALUES(321452,'Bowser','William','C', '12-Feb-75', 42,'So',2.84,2134);

REM insert data into the ENROLL table (first record given)

INSERT INTO ENROLL VALUES(10014,321452,'C');

COMMIT;
