MySQL的：通過ID，改變ID選擇行，並將其插入到另一張表

Question

我有兩個表，A和B.

我想選擇基於它的B行的主鍵，改變主鍵爲不同的值，然後插入該行到A.

事情是這樣的：

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

是否有一個解決方案？

Answer 1

也許像

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

Answer 2

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