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
