oracle 增加字段

之前很多表增加很多相同的字段，一个一个添加太慢烦了，于是用了以下的方法
alter table t_xmlc_batch_out_head_bak add 
(  SENDRECEIVEFLAG     VARCHAR2(1) default 0,
  SENDRECEIVEOPERATOR VARCHAR2(50),
  SENDRECEIVEDATE     DATE,
  DECLAREAPPLICANT    VARCHAR2(50),
  DECLAREDATE         DATE,
  DECLAREAPPROVEFLAG  VARCHAR2(1) default 0,
  DECLAREAPPROVEDATE  DATE

);

comment on column t_xmlc_batch_out_head_bak.SENDRECEIVEFLAG
  is \'货物实际收发标志(0-未确认；1-已确认；)\';
comment on column t_xmlc_batch_out_head_bak.SENDRECEIVEOPERATOR
  is \'货物实际收发人    \';
comment on column t_xmlc_batch_out_head_bak.SENDRECEIVEDATE
  is \'货物实际收发日期 \';
comment on column t_xmlc_batch_out_head_bak.DECLAREAPPLICANT
  is \'货物实际申报申请人 \';
comment on column t_xmlc_batch_out_head_bak.DECLAREDATE
  is \'货物实际申报日期 \';
comment on column t_xmlc_batch_out_head_bak.DECLAREAPPROVEFLAG
  is \'货物实际申报审批标志\';
comment on column t_xmlc_batch_out_head_bak.DECLAREAPPROVEDATE
  is \'货物实际申报审批日期 \';

 

oracle 时间赋值

 update T_XMLC_BILL_HEAD_PRE set  DeclareApplicant=\'冯谊\',DeclareApproveFlag=1,DeclareDate=to_date(\'2016/1/14 16:11:37\',\'yyyy-MM-dd:hh24:mi:ss\') where oid=\'ea1d5c38-d18f-45dd-8c1e-afd5a40ea93d\';
