MySQL的兩個表列複製到不同的列名

Question

另一個表我有兩個表：

頁1

+---------------+-------------+ 
| id   | int   | 
+---------------+-------------+ 
| content  | medium_text | 
+---------------+-------------+ 
| date_modified | int   | 
+---------------+-------------+ 

頁2

+---------+-------------+ 
| id  | int   | 
+---------+-------------+ 
| content | medium_text | 
+---------+-------------+ 
| date | int   | 
+---------+-------------+ 

我無法複製content和date_modified列從pages1表到pages2表中的content和date列。

我得到Unknown column錯誤，我試圖使用AS（別名），如果它是不匹配的，雖然我100％確定列存在。我用厭惡的蜱和整個九碼：

INSERT INTO pages2 (`content`, `date`) VALUES 
(SELECT `content`, `date_modified` FROM `pages` WHERE `pages2`.`id` = `pages`.`id`); 

Answer 1

嘗試此查詢：從你的INSERT語句

INSERT INTO pages2 (`content`, `date`) 
SELECT `content`, `date_modified` FROM `pages` WHERE `pages2`.`id` = `pages`.`id`; 

Answer 2

INSERT INTO pages2 (`content`, `date`) 
SELECT `content`, `date_modified` 
FROM `pages` 
inner join pages2 on `pages`.`id` = `pages2`.`id`; 

Answer 3

INSERT INTO pages2 (`content`, `date`) 
SELECT `content`, `date_modified` FROM `pages`
