操作數應該包含1列（s）？它可以但仍然錯誤。這是一個錯誤？

Question

我有一個嚴重的奇怪問題。我敢肯定我沒有做錯任何事在這行代碼：

INSERT INTO 
oc_address  
    (`cust_id`, `firstname`, `lastname`, `address_1`, `city`, `postcode`, `country_id`) 
SELECT   
    (`cust_id`, `first_name`, `last_name`, `address`, `city`, `postalcode`, `country`) 
FROM old_customer; 

儘管如此，我得到的消息「＃1241 - 操作數應包含1列（S）」

是否anybony看到的東西我不你看嗎？我認爲這可能是由地址_1處的_1造成的。但爲什麼會是... 我希望有另一種解釋

Answer 1

去除SELECT ststement列左右()，

INSERT INTO oc_address (cust_id, firstname, lastname, address_1, city, postcode, country_id) 
SELECT cust_id, first_name, last_name, address, city, postalcode, country 
FROM old_customer;

刪除符號爲您的列名稱和()在您的SELECT。

INSERT INTO 
    oc_address  
    (cust_id, firstname, lastname, address_1, city, postcode,country_id) 
    SELECT   
    cust_id, first_name, last_name, address, city, postalcode, country 
    FROM old_customer;
