I never liked the error/debug data oracle returns. They are not telling me on what line I did what wrong or they couldn't compile/execute what.
I really can't see what I am doing wrong with this command:
CREATE TABLE grad_candidates
(
student_id NUMBER(6) NOT NULL UNIQUE AUTO_INCREMENT,
last_name VARCHAR2(20) NOT NULL,
first_name VARCHAR2(20) NOT NULL,
credits NUMBER(3) NOT NULL,
graduation_date DATE DEFAULT NULL,
PRIMARY KEY (student_id)
)
I am using the oracle apex (https://iacademy.oracle.com/) for testing
