How do I join two tables from a database in SQL? - mysql

Question

I'm currently working on a project where we have to join two tables in SQL and then create a page to show the result of the two tables combined.
This is what I have so far:
SELECT *
FROM
ANIMAL
LEFT OUTER JOIN
FOOD_PORTION
ON
ANIMAL = FOOD_PORTION
and then a second page where the outcome should be:
CREATE TABLE ANIMAL(
AnimalID CHAR(5) PRIMARY KEY,
AnimalName CHAR(50) NOT NULL,
Species CHAR(50) NOT NULL,
Weight INT NOT NULL,
DOB DATE NOT NULL,
ExhibitID CHAR(5) REFERENCES EXHIBIT(ExhibitID)
);
CREATE TABLE FOOD_PORTION(
PortionSize INT NOT NULL,
AnimalID CHAR(5) REFERENCES ANIMAL(AnimalID)
);
SELECT C.Name
FROM ANIMAL AS C
UNION
SELECT S.Name
FROM FOOD_PORTION AS S

This should give you what you need. Using tadman's suggestion to change the char column to INT. Also changing the CHAR to VARCHAR columns.
I also made the ID's in each table Identity columns (so they will auto populate).
CREATE TABLE ANIMAL(
AnimalID INT PRIMARY KEY IDENTITY,
AnimalName VARCHAR(50) NOT NULL,
Species VARCHAR(50) NOT NULL,
Weight INT NOT NULL,
DOB DATE NOT NULL,
ExhibitID CHAR(5) REFERENCES EXHIBIT(ExhibitID)
);
CREATE TABLE FOOD_PORTION(
PortionSize INT IDENTITY,
AnimalID INT REFERENCES ANIMAL(AnimalID)
);
SELECT A.*, FP.*
FROM Animal A
INNER JOIN Food_Portion FP ON A.AnimalID = FP.AnimalID
