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
