My SQL query is:
UPDATE REGISTRUDENT set qual=1 WHERE studentolevelsubjects AS sls INNER JOIN courserequirements AS csreq ON sls.subject_id = csreq.subject_id WHERE sls.stud_id = '$stud_id' AND sls.grade_id>=csreq.min_grade AND sls.examno = '$examno' AND csreq.course_id = '$course_id'
I'm having issue comparing two different table to get if a registrant qualified based on the course requirement I need help
course requirement table
The subject passed by the student in exams
I intend updating and setting the qual =1 if the student qualifies
