我正在使用cakephp 2.0框架。我想计算每个类别的记录数。 这里我有两张桌子

 <?php
        $homeBrands1 =mysql_query("SELECT b.MASTER_ID,b.IMAGES,b.PAGE,b.HOME_LOGO,b.STATUS,m.ID,m.TITLE,m.LOGO FROM cms as b
                      INNER JOIN master as m on m.ID=b.MASTER_ID WHERE b.PAGE='homebrands' AND b.POSITION=1");
        $homeResult1 =mysql_fetch_array($homeBrands1);

        $homeBrands3 =mysql_query("SELECT b.MASTER_ID,b.IMAGES,b.PAGE,b.STATUS,b.HOME_LOGO,m.ID,m.TITLE,m.LOGO FROM cms as b
                      INNER JOIN master as m on m.ID=b.MASTER_ID WHERE b.PAGE='homebrands' AND b.POSITION=3");
        $homeResult3 =mysql_fetch_array($homeBrands3);

        $homeBrands2 =mysql_query("SELECT b.MASTER_ID,b.IMAGES,b.PAGE,b.STATUS,b.HOME_LOGO,m.ID,m.TITLE,m.LOGO FROM cms as b

        $homeResult4 =mysql_fetch_array($homeBrands4);

        $homeBrands5 =mysql_query("SELECT b.MASTER_ID,b.IMAGES,b.PAGE,b.STATUS,b.HOME_LOGO,m.ID,m.TITLE,m.LOGO FROM cms as b

          </div>
       <div style="clear:both"></div>
  </li>

  </ul>

      </div>

我使用此查询获取此数据： - 

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

这时我打印这个：

$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");

现在，您可以看到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 ) ) 为appointment_icon_id的瑜伽，1 appointment_icon_id访问，反之亦然。 我想要算上所有这些类别。 像：

1 个答案:

答案 0 :(得分：2)

所有你需要的是：

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
