Question

我可以像这样在我的数据库中复制一行：

INSERT into `product` (productCode, title, description, price, productGroup)
    SELECT productCode, title, description, price, productGroup
    FROM `product`  
WHERE productCode = $_GET['id']

但我希望productCode与我复制的行具有不同的值。我希望它是：$productCode

我该怎么做？

Answer 1

您可以根据需要更改产品代码值

INSERT into `product` (productCode, title, description, price, productGroup)
SELECT 'your product code value' AS productCode, title, description, price, productGroup
FROM `product`  
WHERE productCode = ".$_GET['id']

Answer 2

您可以将其添加到insert：

中

INSERT into `product` (productCode, title, description, price, productGroup)
    SELECT $productCode, title, description, price, productGroup
    FROM `product`  
WHERE productCode = $_GET['id'];

如果您从应用程序代码中调用此参数，我建议您使用此参数和id。

Answer 3

这将有效：

INSERT into `product` ($productCode, title, description, price, productGroup)
    SELECT productCode, title, description, price, productGroup
    FROM `product`  
WHERE productCode = $_GET['id']

Answer 4

INSERT into `product` (productCode, title, description, price, productGroup)
    SELECT $productCode, title, description, price, productGroup
    FROM `product` p
    WHERE p.productCode = $_GET['id'];

Answer 5

$ _ GET ['id']必须在字符串中。用'或'

包装id

'INSERT into product (productCode, title, description, price, productGroup) SELECT'.$productCode.', title, description, price, productGroup FROM product WHERE productCode = "'.$_GET['id'].'"';

Answer 6

这样做：

INSERT into `product` (productCode, title, description, price, productGroup)
SELECT "$productCode", title, description, price, productGroup
FROM `product`  
WHERE productCode = ".$_GET['id']

使用主键复制数据库中的行
