選擇所有，但在JOIN元素MySQL

Question

我有代碼在這裏加入兩個表。但是，我不想從帳戶數據庫中獲取密碼元素。我怎麼能這樣做？

"SELECT f.*, a.* 
    FROM Following as f 
    JOIN Accounts as a on f.followingUserID = a.id 
    WHERE `followingUserID` = '$acID' 

Answer 1

命名列而不是全部檢索它們。

取而代之的是*：

a.ColumnName1，a.ColumnName2等....

Answer 2

如果你不想選擇一個密碼元素，你需要改變a.*選擇每列單獨即

SELECT f.*, a.account_id, a.name 
FROM following as f 
JOIN accounts as a on f.followingUserId = a.id 
WHERE followingUserID = '$acID' 

Answer 3

沒有SQL約定「除了......所有列」 - 它要麼全部，或者你手工定義列表：

SELECT f.*, 
     a.col1, a.col2, 
     a.`col name using spaces not good` 
    FROM FOLLOWING as f 
    JOIN ACCOUNTS as a on f.followingUserID = a.id 
WHERE f.followingUserID = '$acID'
