query function in cake php

Question

Я пишу код в php, чтобы в основном «отображать» данные из базы данных mySQL в другую базу данных. Я использую код следующим образом:

$results = $this->query("select PT_FS_DATA_ID from PATIENT_FLOWSHEET_DATA where 
    DT_LAST_UPDATED_TIME = (select top 1 DT_LAST_UPDATED_TIME from PATIENT_FLOWSHEET_DATA 
    order by DT_LAST_UPDATED TIME desc) group by PT_FS_DATA_ID;"); 

однако, я получаю сообщение об ошибке:

syntax error, unexpected T_VARIABLE, expecting T_FUNCTION 

Везде я смотрю это, кажется, правильный синтаксис. Здесь что-то не хватает? Я попытался поставить контроллер там $this->controllerName->query, но это тоже не сработало.

Полный код:

class CaExtraFlowsheetFields extends CaBase { 
public $name = 'CaExtraFlowsheetFields'; 

/* 
NOTE: This is to take all the fields in flowsheet and 
maps their id's. 
*/ 
//public $useTable = 'ANSWER_ENTRY'; 
public $useTable = 'PATIENT_FLOWSHEET_DATA'; 
public $primaryKey = 'PT_FS_DATA_ID'; 

protected function getPrimaryKeyValue(
    $hospital_id, 
    $patient_id, 
    $admission_id = null 
) { 

return $patient_id; 
} 

//*CHANGE BEGIN* 
$results = $this->query("select PT_FS_DATA_ID from PATIENT_FLOWSHEET_DATA where 
DT_LAST_UPDATED_TIME = (select top 1 DT_LAST_UPDATED_TIME from PATIENT_FLOWSHEET_DATA 
order by DT_LAST_UPDATED TIME desc) group by PT_FS_DATA_ID;"); 

protected $filedMethodMappings = array(

    'Method_GO' => array(
     CaBase::KEY_MAPPING_LOGIC_COMPLEXITY => CaBase::LEVEL2_COMPLEXITY, 
     CaBase::KEY_FIELD_LOGIC_NAME   => 'wsMethod_GO', 
);

    foreach($results as $value){ 

     $questionName = ''.$value; 
     $msg_prefix = $this->name . "::" . __FUNCTION__ . ": ". "arrivez-vouz" ; 
     $ret = $this->wsLookUpField($params,$questionName,$msg_prefix); 
     return $ret; 
    } 
    unset($value); 
}

public function wsLookUpField($params,$questionName,$msg_prefix){ 

$arrayValues=array(); 
    try{  
     $hospital_id = $params[Constants::KEY_HOSPITAL_ID]; 
     $patient_id = $params[Constants::KEY_PATIENT_ID]; 
     $admission_id = $params[Constants::KEY_ADMISSION_ID];

      $params = array(
      'conditions' => array(
       $this->name . '.PID'    => $patient_id, 
       $this->name . '.PT_FS_DATA_ID'  => $questionName,   
      ),

      ), 
      'fields' => array(
       $this->name . '.FS_VALUE_TEXT', 
      ) 
     ); 

    $rs = $this->find('first', $params); 

    /* check to make sure $rs has received an answer from the query 
     and check to make sure this answer is a part of the most recent 
     database entries for this note */ 
    if (false != $rs) {

       $msg = $msg_prefix . "Data obtained successfully."."<br>".$result; 
      $result = $rs; 
      $ret = WsResponse::getResponse_Success($msg, $result); 
     } catch (Exception $e) { 
      $msg = $msg_prefix . "Exception occurred."; 
      $ret = WsResponse::getResponse_Error($msg); 
     } 
    /*answer was not part of most recent database entries, meaning no

    } else {

    } catch (Exception $e) {

Answer 1

Вот что вы делаете:

class ABC { 

    $result = 'whatever'; 

} 

Вы не можете объявить переменную там!

---

код должен быть внутри метода/функции ...

class ABC 
{ 
    public function wsMethod_GO ($params) 
    { 
     $result = 'whatever'; 
    } 
}
