1、只拷贝表结构,不拷贝数据

select * into b from a where 11;
Copy after login

 

2、表数据迁移 表b已经存在:

insert into b (d, e, f) select a, b, c from a;
Copy after login

     表b原先不存在:

create table b (select a, b, c from a);
Copy after login

 

3、创建临时表

      创建临时表的语法很简单,临时表存在内存中,会话结束即消失:

create temporary table a (...);
Copy after login

 

4、创建视图

      视图属于数据库:

create view test.myView as select a, b from a;
Copy after login
