我有以下DDL
和DML
声明:
create table emp_details (
ID number(2) constraint t_pk primary key,
F_Name varchar(10) not null,
L_Name varchar(10) not null,
DOB date,
Mob_no number(10),
City varchar(10),
PIN number(5),
Gender char(1),
Designation varchar(15),
Join_Date date,
);
insert into emp_details values (01,'John','Wick','1990-07-05',9856482358,'Goa',403001,'M','SDE II', '2015-01-08');
然后,我得到ORA-01843
. 那么,可能是什么问题?
