Answer 3

TRy this for this we need to use group_contact seperate by ' '.

SELECT staff.name,
  staff.designation_id_designation,
  staff.status_id_status,
  GROUP_CONCAT(Concat_Ws('=', leave_remain.leave_type_id_leave_type, leave_remain.days) SEPARATOR ' ') AS remain
FROM staff 
INNER JOIN
  leave_remain 
ON 
staff.id_staff = leave_remain.staff_id_staff
GROUP BY staff.designation_id_designation,
         staff.name,
         staff.status_id_status;
