The example of this article describes the cakephp2.X multi-table joint query join and the method of using paging query. Share it with everyone for your reference, the details are as follows:

Format parameters:

public function getconditions($data){
  $this->loadModel("Cm.LoginHistory");
  $conditions = array();
  foreach ($data as $key=>$val){
    if($key=='start_date'){
      $conditions['LoginHistory.logintime >=']=trim($val);
    }elseif ($key=='end_date'){
      $conditions[&#39;LoginHistory.logouttime <=&#39;]=trim($val);
    }elseif ($key==&#39;selectvsoftid&#39; and $val !=&#39;&#39;){
      $conditions[&#39;LoginHistory.LOGINSUBSYSTEM LIKE&#39;]=&#39;%&#39;.trim($val).&#39;%&#39;;
    }elseif ($key==&#39;username&#39; and $val !=&#39;&#39;){
      $conditions[&#39;LoginHistory.USERNAME LIKE&#39;]=&#39;%&#39;.trim($val).&#39;%&#39;;
    }elseif ($key==&#39;vdevicename&#39; and $val !=&#39;&#39;){
      $conditions[&#39;LoginHistory.WINDOWNAME LIKE&#39;]=&#39;%&#39;.trim($val).&#39;%&#39;;
    }elseif ($key==&#39;selectvsoftid&#39; and $val !=&#39;&#39;){
      $conditions[&#39;LoginHistory.PHDEVICENAME LIKE&#39;]=&#39;%&#39;.trim($val).&#39;%&#39;;
    }
  }
  return $conditions;
}

Paging query:

$fields = array(&#39;LoginHistory.windowname&#39;,&#39;LoginHistory.loginsubsystem&#39;,&#39;VirtualDevice.PHDEVICEID&#39;,&#39;LoginHistory.userid&#39;, &#39;VirtualDevice.SYSTYPEID&#39;,&#39;UserInfo.USERNAME&#39;,&#39;"SUM"(LoginHistory.LOGOUTTIME-LoginHistory.LOGINTIME) moument&#39;,&#39;UserInfo.USERNAME&#39;,&#39;DeviceInfo.DEVICENAME&#39;);
$group=array(&#39;LoginHistory.windowname&#39;, &#39;LoginHistory.loginsubsystem&#39;, &#39;LoginHistory.userid&#39;,&#39;UserInfo.USERNAME&#39;,&#39;DeviceInfo.DEVICENAME&#39;,&#39;VirtualDevice.SYSTYPEID&#39;,&#39;VirtualDevice.PHDEVICEID&#39;);
$this->paginate = array(&#39;conditions&#39;=>$conditions,&#39;fields&#39;=>$fields,&#39;group&#39;=>$group,&#39;limit&#39;=>9,&#39;joins&#39; => array(
   array(
     &#39;alias&#39; => &#39;UserInfo&#39;,
     &#39;table&#39; => &#39;SMM_USERINFO&#39;,
     &#39;type&#39; => &#39;LEFT&#39;,
     &#39;conditions&#39; => &#39; LoginHistory.USERID=UserInfo.USERID &#39;,
   ),
   array(
     &#39;alias&#39; => &#39;VirtualDevice&#39;,
     &#39;table&#39; => &#39;ET_NMVIRTUALDEVICEINFO&#39;,
     &#39;type&#39; => &#39;LEFT&#39;,
     &#39;conditions&#39; => &#39; LoginHistory.WINDOWNAME=VirtualDevice.DEVICENAME &#39;,
   ),
   array(
     &#39;alias&#39; => &#39;DeviceInfo&#39;,
     &#39;table&#39; => &#39;ET_NMDEVICEINFO&#39;,
     &#39;type&#39; => &#39;LEFT&#39;,
     &#39;conditions&#39; => &#39; VirtualDevice.PHDEVICEID=DeviceInfo.DEVICEID &#39;,
   ),
 ));
$LoginHistory = $this->paginate(&#39;LoginHistory&#39;);
$this->set(&#39;loginhistory&#39;,$LoginHistory);
