Please don't be stubborn and I entered the code you gave me once, but there's no data at all. I want the perfect code for the question, and please refer to the picture in the data table I attached, and the code I entered at the bottom of the question doesn't show any data at all. So I want a different code. And never make a new data table and use the table pictures in the pictures I attached. Please don't write the same code as this because the code I wrote down is wrong. Please give me another code that fits the question.
Question
single SQL statement unless otherwise specified (you can use UNION/INTERSECT/EXCEPT and the WITH clause if needed). Provide your answers and screenshots of the results in the required areas. Your SQL statements should have the correct logic and display the correct results as well.
Q1- Find the course(s) taken by the fewest students in the year 2006. The result should display the course title and the number of students. If a student has taken the same course more than once, this student should be counted only once.
Wrong code
with course_enrollment as
(
select course_id, count(distinct student_id) as number_students
from takes
where year = 2006
group by course_id
)
select title, number_students
from course_enrollment as ce join course as c on ce.course_id = c.course_id
order by number_students;
