1. 復制表結構及其數據：

復制代碼 代碼如下:

create table table_name_new as select * from table_name_old

復制代碼 代碼如下:

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

復制代碼 代碼如下:

create table table_name_new like table_name_old

如果兩個表結構一樣：

復制代碼 代碼如下:

insert into table_name_new select * from table_name_old

復制代碼 代碼如下:

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