我想将当前日期插入到我的记录中，首先我成功执行了这个查询。
insert into Member values (1, 'Richa Sharma', 'Pune', TO_DATE('10-Dec-05', 'DD-MM-YY'), 'Lifetime', '25000', 5, 50);
然后在执行以下查询时，我得到了上面的错误代码。
insert into Member values (2, 'Garima Sen', 'Pune', SYSDATE, 'Annual', 100, 3, NULL);
编辑：这是我用来创建表的查询。
create table Member (Member_Id number(5),
Member_Name varchar2(30),
Member_Address varchar2(50),
Acc_Open_Date date,
Membership_Type varchar2(20),
Fees_Paid number(6),
Max_Books_Allowed number(2),
Penalty_Amount number(7,2),
PRIMARY KEY(Member_Id),
CHECK (Membership_Type IN ('Lifetime',' Annual', 'Half Yearly',' Quarterly')));
