mysql - 将项目从一个数据库插入到另一个 SQL 语法

Question

我正在尝试将项目从一个数据库的名为 items 的表复制到另一个数据库的名为 items 的表。我在下面有一个 mysql 脚本，但它给出了一个错误。

INSERT INTO walmart.items 
(title, location, created_at, updated_at, image_url, url, price) 
VALUES 
(
    SELECT title, location, created_at, updated_at, image_url, url, price 
    FROM warehouse.items 
    WHERE url LIKE '%walmart.com%'
);

我相当确定这主要是一个语法问题，而且我的逻辑是正确的。我尝试了几种不同的配置，但不断收到类似的错误。

收到错误:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT title, location, created_at, updated_at, image_url, url, price FROM old_t' at line 1

你插入的选择是错误的:

INSERT INTO walmart.items (title, location, created_at, updated_at, image_url, url, price)
SELECT 
title, 
location, 
created_at, 
updated_at, 
image_url, url, 
price 
FROM warehouse.items 
where url LIKE '%walmart.com%';
