oracle 表複製

1. 複製表結構及其數據：

create table table_name_new as select * from table_name_old

 

2. 只複製表結構：

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. 只複製表數據：

表結構相同

insert into table_name_new select * from table_name_old

表結構不一樣

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