--复制表结构及其数据

create table table_name_new as select * from table_name_old; 

--只复制表结构

create table table_name_new as select * from table_name_old where 1=2;

--create table table_name_new like table_name_old  实测行不通

--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;
