Oracle中复制表结构和表数据

1. 复制表结构及其数据:
create table table_name_new as select * from table_name_old

2. 只复制表结构:
create table table_name_new as select * from table_name_old where 1=2;

或者:
create table table_name_new like table_name_old

3. 只复制表数据:
如果两个表结构一样:
insert into table_name_new select * from table_name_old

如果两个表结构不一样:
insert into table_name_new(column1,column2...) select column1,column2... from table_name_old

4.查询oracle用户创建时间
select t.username, t.account_status, t.created, t.default_tablespace
  from DBA_USERS t
 order by t.created desc;
