How do I assign tha开发者_如何学编程t to a new table?


insert into old_farts
select * from users where age > 5;

Here's the reference page.


At least in Oracle you can do something like

CREATE TABLE SOME_KIDS AS
  SELECT * FROM USERS WHERE AGE > 5;


You need to use the INSERT...SELECT syntax -

INSERT INTO NewTable SELECT * FROM Users WHERE AGE > 5

(Edited to add: In SQL that would be SELECT * INTO NewTable FROM Users WHERE AGE > 5)


It sounds like what you actually want is a view.

CREATE OR REPLACE VIEW users_over_five AS (SELECT * FROM users WHERE age > 5);

Unless you want a non-normalized database, or are just moving data around for maintenance, a view is the way to go.
