MySQL：按ID选择行，更改ID，然后将其插入另一个表

Question

我有两个表，A和B。

我想根据其主键从B中选择一行，将主键更改为其他值，然后将该行插入A。

像这样：

INSERT INTO A SELECT id, title, date FROM B WHERE B.id="4" UPDATE B SET id="5";

有解决方案吗？

Answer 1

INSERT INTO A(id, title, date)
SELECT 5 AS id, title, date FROM B WHERE B.id="4";
#      ^--- here is the trick

Answer 2

也许像

insert into a (select id as "new_id", title, date from b where b.id="4")
