oracle 表复制

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：

表结构相同

insert into table_name_new select * from table_name_old

表结构不一样

insert into table_name_new(column1,column2...) select column1,column2... from table_name_old
