Horse with columns:
ID - integer, primary key
RegisteredName - variable-length string

Student with columns:
ID - integer, primary key
FirstName - variable-length string
LastName - variable-length string

Create the LessonSchedule table with columns:

StudentID - integer with range 0 to 65 thousand, foreign key references Student(ID)
LessonDateTime - date/time, not NULL, partial primary key

If a row is deleted from Horse, the rows with the same horse ID should be deleted from LessonSchedule automatically.

Note: Table and column names are case sensitive in the auto-grader.

CREATE TABLE Horse (
ID SMALLINT UNSIGNED AUTO_INCREMENT,
RegisteredName VARCHAR(15),
PRIMARY KEY (ID)
);

CREATE TABLE Student (
ID SMALLINT UNSIGNED AUTO_INCREMENT,
FirstName VARCHAR(20),
LastName VARCHAR(30),
