The database has three tables for tracking horse-riding lessons:
Horse with columns:
ID - primary key
RegisteredName
Breed
Height
BirthDate
Student with columns:
ID - primary key
FirstName
LastName
Street
City
State
Zip
Phone
EmailAddress
LessonSchedule with columns:
HorseID - partial primary key, foreign key references Horse(ID)
StudentID - foreign key references Student(ID)
LessonDateTime - partial primary key
Write a SELECT statement to create a lesson schedule with the lesson date/time, horse ID, and the student's first and last names. Order the results in ascending order by lesson date/time, then by horse ID. Unassigned lesson times (student ID is NULL) should not appear in the schedule.
Hint: Perform a join on the Student and LessonSchedule tables, matching the student IDs
