您好我是Oracle新手并忘记了如何输入日期。我尝试了很多变化，似乎无法得到它，而且我已经在互联网上看了但是找不到正确的例子。我的表设置如下：hiredate DATE，（DATE是我假设默认输入，但默认值是什么）。
感谢您的帮助。
这是我的代码：
SQL> SET LINESIZE 120
SQL> SET PAGESIZE 45
SQL> SET FEEDBACK 1
SQL> SET ECHO ON
SQL>
SQL> DROP TABLE employee
2
SQL> CREAT TABLE student
SP2-0734: unknown command beginning "CREAT TABL..." - rest of line ignored.
SQL> CREATE TABLE employee
2 (
3 empno NUMBER(4)CONSTRAINT employee_empno_PK PRIMARY KEY,
4 empname VARCHAR(10),
5 job VARCHAR(10),
6 manager NUMBER(4),
7 hiredate DATE,
8 salary NUMBER(7,2),
9 commission NUMBER(7,2),
10 deptno NUMBER(2)
11 );
Table created.

Hello, I am new to MySQL and forgot how to properly INSERT at DATE when using MySQL Plus. I have tried many different variations as you will be able to see and I can't seem to figure it out. I also looked on the internet but always find examples where they make there own formats. What is the correct way to insert a date when the table was created using: hiredate

答案 0 :(得分：1)
您可以使用TO_DATE功能：
TO_DATE('11/17/1981', 'MM/DD/YYYY')
它允许您将日期指定为字符串，然后将其格式指定为Oracle，以便将其转换为日期。
或者你可以使用日期文字：
date '1981-11-17'
答案 1 :(得分：0)
日期在SQL中格式敏感。所以你需要用单引号括起来 （＆＃39; 21日 - 12月2010＆＃39）。如果您的日期不是标准格式，则需要使用特定格式模型使用单行转换函数TO_DATE进行转换。您可以在我的门户网站上找到更多这些语法 http://www.suhelsayyad.com/p/blog-page_14.html
