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

SELECT INTO也有这样的功能；

比如，SELECT * INTO table_new FROM table_old

SELECT * INTO table_new FROM table_old WHERE 1=2
