如何组合此INSERT和SELECT MySQL语句？

Question

这会拉回一行：

SELECT id FROM pin WHERE pinpicsid = '1'

我需要将该语句的结果放到这个X所在的位置：

INSERT INTO user_collection (pinid, username)
VALUES (X, 'ethanwa')

有没有办法将这两者结合起来？

Answer 1

使用INSERT INTO SELECT -statement

INSERT INTO user_collection (pinid, username)
SELECT id, 'ethanwa' FROM pin WHERE pinpicsid = '1'

Answer 2

INSERT INTO user_collection (pinid, username)
SELECT id, 'ethanwa' 
FROM pin 
WHERE pinpicsid = '1'
