如何显示从一张表到另一张表的列

Question

There are 2 tables, a table named species and another table named planet .

I want to display the name, average_height, hair_color, skin_color, homeworld and population . All of the above is in the species table except for population which is in planet table.

What is the query do I have to do to display all of these columns

I am using SQL Developer

Species Table

ID
homeworld
name
average_height
skin_color
hair_color
eye_color
language
average_lifespan
classification

Planet Table

ID
diameter
climate
surface_water
name
rotation_period
terrain
gravity
orbital_period
population

Answer 1

The basic query would be

SELECT s.NAME,
       s.AVERAGE_HEIGHT,
       s.HAIR_COLOR,
       s.SKIN_COLOR,
       s.HOMEWORLD,
       p.POPULATION
  FROM PLANET p
  INNER JOIN SPECIES s
    ON s.HOMEWORLD = p.ID

if SPECIES.HOMEWORLD is in fact a foreign key to PLANET.ID
