запрос на присоединение к MySQL

Question

Я использую 2 следующие таблицы MySQL:

Образец набора данных tbl_customers

+----+--------+---------------+----------+------------+--------+------------+
| id | name   | email         | phone    | product_id | year   | dnt        |          
+----+--------+---------------+----------+------------+--------+------------+
| 2  | tester | test@test.com | 12345678 | 75         | 2010   | 2011/01/01 |
+----+--------+---------------+----------+------------+---------------------+

Пример набора данных tbl_products

+----+----------------+---------------+--------------+
| id | name           | cost          | dnt          |          
+----+----------------+------------------------------+
| 75  | product1      | 500           | 2011/01/01   |
+----+----------------+---------------+--------------+

хочу объединить обе таблицы.

Спасибо!
