SQL- Invalid identifier when creating foreign key- SQL Error: ORA-00904 - sql

Whenever I run the script I keep getting this error:
Error report - SQL Error: ORA-00904: "HORSE_ID": invalid identifier

I am trying to make a foreign key linking the HORSES and MEDICAL table. I think everything looks correct. Can someone let me know what I have done incorrectly? I am using Oracle SQLDeveloper.
CREATE TABLE HORSES (

Name varchar(50) NOT NULL,
Height varchar(50) NOT NULL,
Weight varchar(50) NOT NULL,

Seize varchar(50) NOT NULL,
Score varchar(15) NOT NULL,
Aq_Date varchar(10) NOT NULL,
Ridable varchar(50) NOT NULL,
Trim varchar(50) NOT NULL,
Age varchar(50) NOT NULL
);
/* MEDICAL */
/* ------------------------------------------------------------ */
CREATE TABLE MEDICAL (
Med_ID varchar(50) NOT NULL primary key,
Feed_Ins varchar(4000) NOT NULL,
Special_Vet varchar(2000) NOT NULL,
Coggins varchar(50) NOT NULL,
Vaccs varchar(50) NOT NULL,
Deworm varchar(50) NOT NULL,
CONSTRAINT Horse_ID_HORSES_FK FOREIGN KEY (Horse_ID) REFERENCES HORSES(Horse_ID)
);


You don't have a horse_id column in medical, how do you want it to be fk for that table?

"Syntax error in constraint clause" MS Access creating a table

I keep getting the syntax error in access when trying to add a foreign key to a table. The foreign key is LendorID and it is referenced in another table. What am I doing wrong?
Here is my code for creating the table:
CREATE TABLE BOOK_INVENTORY
(
CRN int NOT NULL PRIMARY KEY,
AuthorLastName varchar(20) NOT NULL,
AuthorFirstName varchar(20) NOT NULL,
BookTitle varchar (100) NOT NULL,
LendorID varchar(5) FOREIGN KEY REFERENCES LENDOR_INFO(LendorID),
);
Here is my code for the table that contains LendorID:
CREATE TABLE LENDOR_INFO
(
LendorID varchar(5) NOT NULL,
LendorLastName varchar(20) NOT NULL,
LendorFirstName varchar(20) NOT NULL,
LendorEmail varchar(100) NOT NULL,
PRIMARY KEY (LendorID)
);

You misspelled the CONSTRAINT keyword. Correct way is down below.
CREATE TABLE PRESENTER

What is breaking my sql program? Incorrect syntax near (

This code section
CREATE TABLE AIRPORT (
Airport_Code int NOT NULL,
City varchar(20) NOT NULL,
State varchar(20) NOT NULL,
Name varchar(25) NOT NULL,
CONSTRAINT PK_AIRPORT PRIMARY KEY (Airport_Code)

Is almost the same as this one but this one is giving me an error and I can't figure out how to fix it
CREATE TABLE AIRPLANE_TYPE (
Company varchar(20) NOT NULL,
Typename varchar(20) NOT NULL,
Max_seats int NOT NULL,
CONSTRAINT PK_AIRPLANE_TYPE (Typename) //error is here (Typename)
)
I am getting the error Incorrect syntax near '('.

Adding the primary key inline with the column will give you a crap auto-generated name for your primary key. I also don't understand how "encouraging primary keys to be on one column" is an added benefit.
CREATE TABLE AIRPLANE_TYPE (
Company varchar(20) NOT NULL,
Typename varchar(20) NOT NULL,
Max_seats int NOT NULL,
CONSTRAINT PK_AIRPLANE_TYPE PRIMARY KEY (Typename)
)

You are missing the PRIMARY KEY. I have a preference for putting this directly in the column definition:
CREATE TABLE AIRPLANE_TYPE (
Company varchar(20) NOT NULL,
Typename varchar(20) NOT NULL PRIMARY KEY,
Max_seats int NOT NULL
);
In addition to a shorter definition, this encourages all primary keys to be only one column -- an added benefit.

HSQLDB Error: unexpected token: FOREIGN

I have the following SQL I am running in my local HSQLDB 2.3.2 database:
CREATE TABLE IF NOT EXISTS countries (
country_id INTEGER GENERATED BY DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1) NOT NULL PRIMARY KEY,
country_version INTEGER NOT NULL,
country_name NVARCHAR(100) NOT NULL,
country_label NVARCHAR(100) NOT NULL,
country_description NVARCHAR(500) NOT NULL
country_code NVARCHAR(10) NOT NULL,
CONSTRAINT uc_countries UNIQUE (country_id, country_version, country_label, country_description, country_code)
);
CREATE TABLE IF NOT EXISTS states (
state_id INTEGER GENERATED BY DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1) NOT NULL PRIMARY KEY,
state_version INTEGER NOT NULL
state_name NVARCHAR(100) NOT NULL,
state_label NVARCHAR(100) NOT NULL,
state_description NVARCHAR(500) NOT NULL,
country_id INT NOT NULL,
FOREIGN KEY (country_id) REFERENCES countries(country_id),
CONSTRAINT uc_states UNIQUE (state_id, state_version, state_label, state_description, country_id)
);
When I run this I get:
Error: unexpected token: FOREIGN
SQLState: 42581
ErrorCode: -5581
What is going on here, and what can I do to fix it?

Is there a difference between INT NOT NULL and INTEGER NOT NULL? Because you have defined the country_id fields by both.
Also, if you insert SET REFERENTIAL_INTEGRITY FALSE; at the top, do you still get this error?

Can't create table in Oracle Developer

Hi I am very new to SQL and having a problem for creating the table.
I have been looking at this code for the past two days now and I can not seem to get it to work. It keeps giving me "ORA-00907: missing right parenthesis" I know that this is a topic that comes up a lot but for some reason none of the examples I have seen has helped me. Can someone please tell me why I got this error and how do I fix it. I am pretty sure that it has nothing to do with my parenthesis, maybe its my CONTRAINTS

The error description is misleading, but the pointer (line 5, column 10) points to exactly after reading the word "INT" ... which, is unknown by him. He should state he doesn't understand that, but he mentions something with parenthesis, which ironically are actually correct. Unfortunately, it happens on occasions that error messages are misleading, and you have to think one step further.

The problem is with your data types. INT is not a valid Oracle datatype. Try this instead:
create TABLE Employee ( EmployeeID VARCHAR(10) PRIMARY KEY,
Name VARCHAR(30) NOT NULL,
Phone NUMBER(10) NOT NULL,
JobTitle VARCHAR(10) NOT NULL );
