Question

我按照这个帖子来构建查询但是我的工作不起作用：MySQL INSERT INTO ... VALUES and SELECT这是我的查询：

INSERT INTO item_category (id,item_name,price ) VALUES
(SELECT id, item_name, price FROM item_info WHERE item_info.price >99);

这是我收到的错误消息：

#1064 - 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 id, item_name, price FROM item_info WHERE item_info.price >99)' at line 2

Answer 1

从select查询插入表的语法不使用VALUES。

INSERT INTO item_category (id, item_name, price)
SELECT id, item_name, price
FROM item_info
WHERE price > 99;

VALUES形式的insert保留用于插入文字元组，例如

INSERT INTO item_category (id, item_name, price)
VALUES
    (1, 'some item', 99);

请注意，我们还可以使用select：

表示上述值insert

INSERT INTO item_category (id, item_name, price)
SELECT 1, 'some item', 99
FROM dual;    -- or some other table

当我们想要将文字与实际列值混合时，这个技巧很有用。

Answer 2

删除Values

INSERT INTO item_category (
    id
    ,item_name
    ,price
    )
SELECT id
    ,item_name
    ,price
FROM item_info
WHERE item_info.price > 99;

Answer 3

删除VALUES并尝试

INSERT INTO item_category (id,item_name,price )
SELECT id, item_name, price FROM item_info WHERE item_info.price >99

会工作!!

MySQL INSERT INTO表1（col1，col2，col3 ...）VALUE（SELECT xxx）不起作用
