充分利用数据库

Question

错误的数据，你可以检查我的database class

当我把这个梅索德

public function getNote() { 
      $epreuve = $this->_db->get('module', array('concour_code', '=', $this->data()->concour_code)); 
      $id = $this->data()->ID; 
      foreach($epreuve->results() as $epreu){ 
       $epreu_code = $epreu->code; 

       echo "<tr>"; 
       echo "<td>".$epreu->epreuve_code."</td><td>".$epreu->designation."</td>"; 
       $module = Database::getInstance()->query("SELECT note_condidat.note,note_condidat.condidat_concour_id,note_condidat.module_code 
             FROM note_condidat, 
             WHERE note_condidat.condidat_concour_id = {$id} AND note_condidat.module_code = {$epreu_code} "); 

       foreach($module->results() as $mod){ 
        echo "<td>".$mod->note."</td>"; 
       } 

       echo "</tr>"; 
      } 
     } 

注： $这个 - >数据（） - > ID 回报用户ID

我收到了错误的数据！它注意到从模块表中未从注表

解决:)

public function getNote() { 
      $epreuve = $this->_db->get('module', array('concour_code', '=', $this->data()->concour_code)); 
      $id = $this->data()->ID; 
      foreach($epreuve->results() as $epreu){ 
       $epreu_code = $epreu->code; 
       $note = Database::getInstance()->query("SELECT condidat_concour.ID,note_condidat.note,note_condidat.condidat_concour_id,note_condidat.module_code,module.code 
                  FROM note_condidat,condidat_concour,module 
                  WHERE note_condidat.condidat_concour_id = '{$id}' AND note_condidat.module_code = '{$epreu_code}' "); 
       echo "<tr>"; 
       echo "<td>".$epreu->epreuve_code."</td>"; 
       echo "<td>".$epreu->designation."</td>"; 
       echo "<td>"; 
       print_r($note->first()->note); echo "<b>/".$epreu->note."</b>"; 
       echo "</td>"; 
       echo "<td>".$epreu->coef."</td>"; 
       echo "</tr>"; 
      } 
     }
