MYSQL：我有两个表。 我想在表 1 中使用 FK 显示表 1 和表 2 中的数据

Question

I am trying to fetch data from two tables. Table 1 is called Location and Table 2 is called Restaurant. Location has a field called RestaurantID (FK) which is the primary key in Restaurant . I want to show the value of column "Location" from table Location and the "RestaurantID" (PK in Restaurant and FK in Location) as well as " Name " value from Table Restaurant . I have attached MySQL table below.

Answer 1

A join should do the trick:

SELECT l.location, l.restaurantid, r.name
FROM   location l
JOIN   restaurant r ON l.restaurantid = r.restaurantid
