Question

This is my schema:

CREATE TABLE item (
    id integer NOT NULL PRIMARY KEY AUTO_INCREMENT,
    title varchar(60) NOT NULL,
    description varchar(900) NOT NULL,
    company_id integer NOT NULL REFERENCES company (id),
    date datetime NOT NULL,
    source_id integer NOT NULL REFERENCES source (id),
    link varchar(255) NOT NULL,
    location_id integer NOT NULL REFERENCES location (id)
);

CREATE TABLE location (
    id integer NOT NULL PRIMARY KEY AUTO_INCREMENT,
    name varchar(255) NOT NULL,
    coordinate varchar(255) NOT NULL,
    location_id integer NOT NULL REFERENCES country (id)
);

CREATE TABLE country (
    id integer NOT NULL PRIMARY KEY AUTO_INCREMENT,
    name varchar(255) NOT NULL
);

CREATE TABLE company (
    id integer NOT NULL PRIMARY KEY AUTO_INCREMENT,
    name varchar(60) NOT NULL,
);

CREATE TABLE source (
    id integer NOT NULL PRIMARY KEY AUTO_INCREMENT,
    name varchar(60) NOT NULL,
);

It is telling me that there is invalid syntax on line four on http://sqlfiddle.com when I put it in and click build schema. I can see no error, can anyone shed some light please?

Also if I have done anything poorly or made any bad decisions please let me know.

Answer 1

You have 2 faulty commas. One at the end of “CREATE TABLE company”, “CREATE TABLE source”.
And create country before location.

CREATE TABLE company (
    id SERIAL PRIMARY KEY,
    name varchar(60) NOT NULL
);

CREATE TABLE country (
    id SERIAL PRIMARY KEY,
    name varchar(255) NOT NULL
);

CREATE TABLE location (
    id SERIAL PRIMARY KEY,
    name varchar(255) NOT NULL,
    coordinate varchar(255) NOT NULL,
    location_id integer NOT NULL REFERENCES country (id)
);

CREATE TABLE source (
    id SERIAL PRIMARY KEY,
    name varchar(60) NOT NULL
);

CREATE TABLE item (
    id SERIAL PRIMARY KEY,
    title varchar(60) NOT NULL,
    description varchar(900) NOT NULL,
    company_id integer NOT NULL REFERENCES company (id),
    date timestamp NOT NULL,
    source_id integer NOT NULL REFERENCES source (id),
    link varchar(255) NOT NULL,
    location_id integer NOT NULL REFERENCES location (id)
);
