sql - ORA-01858 : a non-numeric character was found where a numeric was expected? 即使值是数字？

Question

这是表格

    CREATE TABLE Employee
    (EmpID number(5) primary key,
    SIN Number(9) Not null,
    LastName Varchar2(25) Not null,
    FirstName Varchar2(25),
    Street Varchar2(30),
    City Varchar2(25),
    Province Char(2),
    PostalCode Varchar2(7),
    JobCode Number(4) Not null,
    Foreign Key(JobCode) REFERENCES Job,
    IncomeTax Char(1),
    BirthDate Date,
    HireDate Date,
    JobCodeDate Date)
    TABLESPACE users;

这是我要插入的行，只有三个数值，据我所知，它们都是数字。

INSERT INTO Employee VALUES(97319,516303417,'Novak','Gerry','6803 Park Ave.','Moose Jaw','SK','S6H 1X7',3000,'N','24-Aug-86','07-Jul-03','07-Jul-03');

ERROR at line 1:
ORA-01858: a non-numeric character was found where a numeric was expected

Answer 1

我认为问题出在日期列上，请尝试使用以下语法to_date('07-Jul-03','DD-MON-YY'):

INSERT INTO Employee 
VALUES(97319,516303417,'Novak','Gerry','6803 Park Ave.','Moose Jaw','SK','S6H 1X7',3000,'N',to_date('24-Aug-86', 'DD-MON-YY'),to_date('07-Jul-03','DD-MON-YY'),to_date('07-Jul-03','DD-MON-YY'));
