mysql - mysql 操作数应包含 1 列

Question

我有两个名为的表newlab，deadstock它们都在同一个数据库中，我想将 newlab 的一些字段复制到 deadstock 因为我正在使用以下代码

INSERT INTO deadstock
(MAC,Lab_Code,PC_Name,Purchase_Order_No,
Brand,Model,Price,Processor,Ram,HDD,HDD_Type) 
SELECT (MAC,Lab_Code,PC_Name,Purchase_Order_No,
Brand,Model_Name,Price,Processor,Ram,HDD,HDD_Type)
FROM newlab WHERE PC_Name='".$PC_Name."';

但它给出的操作数应该包含一列错误

Answer 1

试试这个代码

INSERT INTO deadstock
(MAC,Lab_Code,PC_Name,Purchase_Order_No,
Brand,Model,Price,Processor,Ram,HDD,HDD_Type) 
SELECT MAC,Lab_Code,PC_Name,Purchase_Order_No,
Brand,Model_Name,Price,Processor,Ram,HDD,HDD_Type
FROM newlab WHERE PC_Name='".$PC_Name."';
