MYSQL INSERT INTO WITH SELECT无法正常工作？

Question

我正在尝试使用SELECT进行插入，以下查询似乎不会因某些原因而起作用，

INSERT INTO `employer_data` 
(`employer_id`, `data`, `datetime`) 
VALUES 
( SELECT employer_id, employer_id AS data, NOW() AS `datetime` FROM employer ); 

有什么想法吗？

Answer 1

删除values关键字

INSERT INTO `employer_data` 
(`employer_id`, `data`, `datetime`)  
( SELECT employer_id, employer_id AS data, NOW() AS `datetime` FROM employer ); 

Answer 2

语法错误。

尝试：

INSERT INTO `employer_data` 
(`employer_id`, `data`, `datetime`) 
SELECT employer_id, employer_id AS data, NOW() AS `datetime` FROM employer;
