Answer 1

在第7行HH24:MI:SS')) ，之后添加逗号，你应该没问题

 7  M_TIME date generated always as (to_CHAR(M_DATE_HH_MM,'HH24:MI:SS')) , 
                                                                        / \
                                                                         |
 8  M_EMAIL VARCHAR(20) FOREIGN KEY REFERENCES MEMBER(M_EMAIL),

我想纠正这个错误
