你試圖達到這樣的結果的地方在哪裏？ – 2014-09-29 09:15:16

請注意，order_items中的sn列（可能是）多餘的 – Strawberry 2014-09-29 09:33:19

我是mysql新手。我可以寫簡單的querries。我試圖用嵌套querry實現這一點，但它並沒有工作......這對我來說是一種火箭科學 – user1362473 2014-09-29 09:52:09

Please try with this query: 

SELECT orders.order_id as 'Order ID', 
    companies.name as 'Company Name', 
    contacts.name as 'Contact Name ', 
    CONCAT(brands.brand , ', ' ,colors.colcor) as 'Car Ordered', 
    order_items.price as 'price' 
    FROM order_items 
    left outer join orders on orders.order_id = order_items.order_id 
    left outer join contacts on orders.contact_id = contacts.contact_id 
    left outer join companies on orders.company_id = companies.company_id 
    left outer join cars on order_items.car_id =cars.car_id 
    left outer join colors on cars.color_id = colors.color_id 
    left outer join brands on cars.brand_id = brands.brand_id 
    order by brands.brand asc

謝謝。它的工作除了「汽車訂購」欄。汽車有序列在所有行中顯示「0」零。此列應顯示「母品牌，子品牌，顏色」即「Nissa，陽光明媚，綠色」 – user1362473 2014-10-01 10:06:50

請再試一次 – jainvikram444 2014-10-01 10:52:29

以前的例子是MS-SQL服務器，現在加入concat函數加入 – jainvikram444 2014-10-01 10:53:26
