取到的dto類型的數據怎么插入數據庫？

oracle中如何插入date類型的數據方法如下：

insert into tabname(datecol) value(sysdate) ; -- 用date值

insert into tabname(datecol) value(sysdate+1) ; -- 用date值

insert into tabname(datecol) value(to_date('2014-02-14','yyyy-mm-dd')) ; -- 用to_date

insert into tabname(datecol) value(to_date('2014-02-14 20:47:00','yyyy-mm-dd hh24:mi:ss')) ; -- 用to_date

insert into tabname(datecol) value(to_date('20140214','yyyymmdd')) ; -- 用to_date

insert into tabname(datecol) value(to_date('20140214204700','yyyymmddhh24miss')) ; -- 用to_date

select table_name,tablespace_name from user_tables where table_name='EMP';

drop table EMP;

create table EMP

(

EMPNO NUMBER(6) not null unique,

ENAME varchar2(20),

JOB varchar2(20),

MGR varchar2(20),

HIREDATE date,

SAL varchar2(20),

COMM varchar2(20),

DEPTNO varchar2(20)

);

INSERT INTO EMP VALUES(44449, '小明', '工程師', 'ligang',

to_date('20140214204700','yyyymmddhh24miss'), '1000', '12345', 'test');

commit;

select xx.empno,xx.ename,xx.job,xx.mgr,xx.hiredate,xx.sal,xx.comm,xx.deptno

from (select rownum id1,emp.* from emp where rownum<4) xx

where id1>0;
