Wie erhält man die Anzahl der einzelnen Kategorien mit Gruppen?

Question

Ich benutze CakePHP 2.0 Framework. Ich möchte die Anzahl der Datensätze jeder Kategorie zählen. Hier ich habe zwei Tabellen

eve_appointment_icons ->having columns- appointment_icon_id,appointment_icon_type_name 
eve_appointments ->having columns- id, appointment_icon_id 

Ich hole haben diese Daten mit dieser Abfrage: -

$this->EveAppointment->query("SELECT 
        a.appointment_type 
        d.appointment_icon_id, 
        a.appointment_icon_id , 
        d.appointment_icon_type_name, 
       FROM eve_appointments a, 
        eve_appointment_icons d 
       WHERE a.appointment_type =1 
       AND d.appointment_icon_id = a.appointment_icon_id 

      UNION 
       SELECT 
        a.appointment_type 
        d.appointment_icon_id, 
        a.appointment_icon_id , 
        d.appointment_icon_type_name, 

       FROM eve_appointments a, 
        eve_appointment_icons d 
       WHERE a.appointment_type =2 
        AND d.appointment_icon_id = a.appointment_icon_id 
      UNION 
       SELECT 
        a.appointment_type 
        d.appointment_icon_id, 
        a.appointment_icon_id , 
        d.appointment_icon_type_name, 
       FROM eve_appointments a, 
        eve_appointment_icons d 
       WHERE a.appointment_type =3 
        AND d.appointment_icon_id = a.appointment_icon_id"); 

hier, wenn ich drucken diese:

Array 
(
[0] => Array 
    (
     [appointment_icon_id] => 1 
     [appointment_icon_type_name] => Yoga 
    ) 
[1] => Array 
    (
     [appointment_icon_id] => 1 
     [appointment_icon_type_name] => Yoga 
    ) 

[2] => Array 
    (
     [appointment_icon_id] => 2 
     [appointment_icon_type_name] => Visit 
    ) 
[3] => Array 
    (
     [appointment_icon_id] => 3 
     [appointment_icon_type_name] => Physio Therapy 
    ) 

[4] => Array 
    (
     [appointment_icon_id] => 4 
     [appointment_icon_type_name] => Diagnostic 
    ) 
[5] => Array 
    (
     [appointment_icon_id] => 4 
     [appointment_icon_type_name] => Diagnostic 
    ) 
[6] => Array 
    (
     [appointment_icon_id] => 4 
     [appointment_icon_type_name] => Diagnostic 
    ) 
) 

Jetzt können Sie die Yoga sehen, die appointment_icon_id ist 1, besuchen Sie appointment_icon_id2 und umgekehrt für andere. Ich möchte alle diese Kategorien zählen. Like:

appointment_icon_type_name count 
Yoga       2 
Visit       1 
Physio Therapy     1 
Diagnostic      3 

Answer 1

Alles, was Sie benötigen, ist dieses:

select d.appointment_icon_type_name, count(*) 
FROM eve_appointments a, 
eve_appointment_icons d 
WHERE d.appointment_icon_id = a.appointment_icon_id 
group by d.appointment_icon_type_name
