如何使用多值和SELECT語句插入？

Question

我想創建一個查詢與來自其他表，例如值一起插入幾個值：

INSERT INTO table 
(date, user_id, category_id, title, description) 
VALUES 
    ((STR_TO_DATE('04-01-2014', '%b-%d-%Y'), 
    (SELECT id FROM users WHERE username = 'admin' LIMIT 1), 
    (SELECT id FROM categories WHERE category = 'games' LIMIT 1), 
    'title here', 
    'description here') 

然而，這給了我一個錯誤，並且從PHP 500內部服務器錯誤。請幫助。

Answer 1

INSERT INTO table (fields) 
SELECT 
    str_to_date(), 
    users.id, 
    categories.id, 
    'title', 
    'description' 
FROM 
    users 
INNER JOIN 
    categories ON users.key = categories.key 
WHERE 
    users.username = 'admin' AND 
    categories.category = 'games' 

應該這樣做，我認爲......

Answer 2

我敢肯定你需要VALUES後SELECT如果你正在做這種方式。試試這個，看看它是否有效。

INSERT INTO table 
(date, user_id, category_id, title, description) 
VALUES 
SELECT 
    STR_TO_DATE('04-01-2014', '%b-%d-%Y'), 
    (SELECT id FROM users WHERE username = 'admin' LIMIT 1), 
    (SELECT id FROM categories WHERE category = 'games' LIMIT 1), 
    'title here', 
    'description here'
