嘗試

SELECT c.id,c.email,c.phone,CONCAT(c.year,c.id) AS customer_ID,p.name 
FROM table_customer c 
JOIN table_product p 
ON p.id=c.product_id 

Answer 2

SELECT *, 
CONCAT(tbl_customers.year, tbl_customers.id) as customer_id, 
product_name as tbl_products.name, 
customer_id as tbl_customers.id, 
FROM tbl_customers 
JOIN tbl_products ON (tbl_customers.product_id = tbl_products.id)
