Answer 1

Verwendung GROUP_CONCAT

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)) AS remain

     INNER JOIN leave_remain 
      ON staff.id_staff = leave_remain.staff_id_staff 
GROUP BY staff.name, staff.designation_id_designation, staff.status_id_status

Answer 2

Versuchen Sie folgendes:

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; 

Answer 3

versuchen, dies für das wir group_contact seperate verwenden, indem Sie '' benötigen.

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;
