查询两张表并在第二张表中替换一张表中的值 [英] Query two tables and replace values from one table in the second one

问题描述

假设我有两张这样的表:

Say I have two tables like so:

fruits
-------------
id | name   |
-------------
1  | Apple  |
2  | Orange |
3  | Pear   |
-------------

users
-------------------
id | name | fruit |
-------------------
1  | John | 3     |
2  | Bob  | 2     |
3  | Adam | 1     |
-------------------

我想查询这两个表，并在结果中获取用户 ID、他的姓名和水果名称(用户表中的水果 ID 对应于水果的 ID)，如下所示:

I would like to query both of those tables and in the result get user ID, his name and a fruit name (fruit ID in users table corresponds to the ID of the fruit) like so:

--------------------
id | name | fruit  |
--------------------
1  | John | Pear   |
2  | Bob  | Orange |
3  | Adam | Apple  |
-------------------

到目前为止，我尝试通过以下查询加入这两个查询，但没有成功.

I tried joining those two with a query below with no success so far.

"SELECT * FROM users, fruits WHERE fruits.id = fruit"

提前致谢.

推荐答案

你需要像这样JOIN水果表:

SELECT u.id, u.name, f.name FROM users u JOIN fruits f ON u.fruit = f.id
