如何编写一个mysql查询，从一个表读取数据并写入另一个表？

If this is possible, please provide a sample query or two so I can see how it would work. Both tables will be in the same database.

如果可以,请提供一两个示例查询,以便我了解它是如何工作的。两个表都在同一个数据库中。

Thanks!

Pseudo code:

insert into <target-table>
( <column-list> )
select <columns>
  from <source-table>

INSERT...SELECT is the answer; see http://dev.mysql.com/doc/refman/5.1/en/insert-select.html.

INSERT ... SELECT就是答案;请参阅http://dev.mysql.com/doc/refman/5.1/en/insert-select.html。

For example:

INSERT INTO names
SELECT last_name, first_name
FROM people
