SQL查詢獲取客戶名稱

Question

您好我是mysql.i中的新用戶，希望從客戶表中獲取客戶名稱。如果客戶表的客戶ID和工作訂單表的另一個客戶ID應該是相同的。此查詢

Answer 1

嘗試

SELECT c.name 
FROM table_customer c 
INNER JOIN table_work_order w 
ON w.customer_id=c.customer_id 

注：使指數兩個表的customer_id

Answer 2

SELECT C.name FROM customer as C , work_orders as WO 
where C.customer_id = WO.customer_id 
AND WO.work_order_id = 25 

試試這個如果你想獲得工單的客戶名稱。嘗試這個。
