I have a code:
SET @sql_dynamic:= (SELECT GROUP_CONCAT(DISTINCT CONCAT('if(sum(if(attendance_date = "',
date_format(attendance_date, '%Y-%m-%d'),
'",1,0))=0,0,attendance_status) AS `',
date_format(attendance_date, '%M-%d'),'`'
)
) from attendance
);
SET @sql = CONCAT('SELECT studentidnumber, student_fullname, subject_id, ',
@sql_dynamic, '
FROM attendance
WHERE subject_id=1
GROUP BY studentidnumber'
);
