SQL平均价格

我需要一个SQL查询，将显示制造商的名称和平均价格。谢谢

表1产品

+----+---------+-------+--------------+
| ID | Product | Price | Manufacturer |
+----+---------+-------+--------------+
|  1 | Game1   |   100 |            1 |
|  2 | Game2   |    50 |            2 |
|  3 | Game4   |    70 |            1 |
+----+---------+-------+--------------+

表2制造商

+----+-----------+
| Id |   Name    |
+----+-----------+
|  1 | Sony      |
|  2 | Microsoft |
+----+-----------+

只需加入并聚合：

select m.name, avg(p.price) avg_price
from manufacturer m
inner join products p on p.manufacturer = m.id
group by m.id, m.name
