GROUP BY task_name
ORDER BY cast( SUBSTRING( task_name, 5 ) AS unsigned ) ASC"

"select task_name,section_name,ref_student_id from scores where ref_student_id = '".$studentid."' and section_name = 'sm1' GROUP BY task_name order by task_name ASC "

Answer 3

use this

SELECT task_name, section_name, ref_student_id
FROM scores
WHERE ref_student_id = '".$studentid."'
AND section_name = 'sm1'
ORDER BY ltrim(task_name) ASC          //order by should come for ordering....
GROUP BY task_name

instead of

SELECT task_name, section_name, ref_student_id
FROM scores
WHERE ref_student_id = '".$studentid."'
AND section_name = 'sm1'
GROUP BY task_name
