在oracle中如何复制表结构和表数据

1、复制表结构及其数据:

create table table_new as select * from table_old

2、只复制表结构:

create table table_new as select * from table_old where 1=2;

或者

create table table_new like table_old

3、只复制表数据:

如果两个表结构一样:

insert into table_new select * from table_old

如果两个表结构不一样:

insert into table_new(column1,column2...) select column1,column2... from table_old

pasting
