MySQL 插入来自 select 的值

Question

我有这个查询：

INSERT INTO oc_stock_hpp (product_id, buy_price) 
VALUES (
'3337',
(SELECT buy_price
FROM oc_stock_hpp
WHERE product_id ='3337'
ORDER BY id DESC
LIMIT 1)
)

我收到一个错误：

Table 'oc_stock_hpp' is specified twice, both as a target for 'INSERT' and as a separate source for data

我该怎么办？

Answer 1

您可以使用 insert-select 语句并将 product_id 添加到查询中：

INSERT INTO oc_stock_hpp (product_id, buy_price) 
SELECT   product_id, buy_price
FROM     oc_stock_hpp 
WHERE    product_id = '3337'
ORDER BY id DESC LIMIT 1
