I think maybe you want this...
Select *
>From lessons
Left join lessons on
(lessons.lessonID = students.lessonID
AND students.studentID = #studentID#)
Putting the AND in the join clause (and not in the WHERE clause) will give
different results.

Nope. That returns only rows from lessons where either no matching row exists
in the students table at all or where a matching row exists for that student.
In other words, it eliminates any lessons for which there is a match in the
students table, but not for the given student.
