Databases SQL Reporting by Example Day 3: Getting Good at Grouping Most Popular Teacher

Most Popular Teacher4:28

Hi, I seemed to get the same answer to the solution worked question, but my query was different:

'''WITH ELEC_TEACHERS AS''' ( '''SELECT first_name, last_name, name, count(student_id) AS 'CT' FROM TEACHERS''' '''JOIN CLASSES ON teachers.id = classes.teacher_id''' '''JOIN SCHEDULE ON schedule.class_id = classes.id''' '''JOIN SUBJECTS ON subjects.id = classes.subject_id''' '''WHERE GRADE IS NULL''' '''GROUP BY teacher_id''' '''ORDER BY COUNT(student_id) DESC''' ) ''' SELECT first_name, last_name, MAX(CT) FROM ELEC_TEACHERS;'''

IS this okay?


It's okay guys I have re-watched the video and it makes sense. You can just ignore this.

Thanks Mike
