Write a statement that selects a lesson schedule for Feb $1,2020$ with lesson datetimes, student first and last names, and horse registered names. Order the results in ascending order by lesson datetime, then by registered name. Unassigned lesson times $($student ID is NULL$)$ must appear in the results.

Hint: Perform a three$-$way join on LessonSchedule, Student, and Horse. Use the DATE$()$ function to convert datetime to date.
