1. 復制表結構及其數據：
create table table_name_new as select * from table_name_old
2. 只復制表結構：
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. 只復制表數據：
如果兩個表結構一樣：
insert into table_name_new select * from table_name_old
如果兩個表結構不一樣：
insert into table_name_new(column1,column2...) select column1,column2... from table_name_old
