如何从mysql中的两个表中获取信息

Question

我坚持使用mysql， 我需要从基于城市的几个表中获取信息，如下所示：

table1: users contains id, name, city.
table2: users_products contains id, user_id, type.

我想根据城市检索id，city，name，product_id，product_type。 请帮帮我。

Answer 1

select t1.id, t1.city, t1.name, t2.product_id from users t1, products t2
where city = "City Name";

Answer 2

SELECT u.*, up.id AS ProductID, up.type
FROM users_products AS up 
JOIN users AS u
ON u.id = up.user_id
WHERE u.city = "City"
