Hi Abayomi-Rufai,
Thanks for reaching out.
Are you referring to the employees_mod database or the albums/online_courses database? Each database has been assembled with a different purpose, i.e. to test certain SQL skills, so it has been adapted for the exercises provided.
Looking forward to your answer.
Kind regards,
Martin

Hey Abayomi-Rufai,
Thank you for your patience, and I apologize for the delayed response.

If you're referring to the date_completed column in the career_track_student_enrollments table, please note that this field will be NULL for any career track that has not been completed.

If this doesn't address your concern, or if I've misunderstood, please feel free to clarify, and I'd be happy to assist further.
Kind regards,

Yeah it is. But every single record is NULL, meaning nobody actually completed any track, so how are they carrying out the analysis of the completion rate?

Hey again,
The majority of the date_completed records are indeed NULL. However, upon executing the following SQL script, you'll ensure there are 123 records where a completion date is present.
SELECT 
    COUNT(date_completed)
FROM
    career_track_student_enrollments;
Let me know if you encounter other issues.
Kind regards,
