调用函数到模型时出现此错误.

Database Error

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'singleBlockWeekly' at line 1

SQL Query: singleBlockWeekly 

这是我的控制器

class BlackoutController extends CalendarAppController
{
    var $uses = array('Studio','Blackout','BlackoutRepeatTypeDetails','Calendar.Event');
    var $components = array('Accesscontrol','RequestHandler');
    function event_checker()
    {
        $start_date = $this->request->data['start_date'];
        $end_date = $this->request->data['end_date'];
        $endsOn = $this->request->data['endsOn'];
        $repeatType = $this->request->data['repeatType'];
        $blockType = $this->request->data['blockType'];
        $frequency = $this->request->data['freq'];
        $repeatDays = $this->request->data['repeatDays'];

        #single type 
        if($blockType == "single"){
            if($repeatType == "weekly"){
                $dates = $this->Blackout->singleBlockWeekly($start_date,$endsOn,$repeatDays,$frequency);
                debug($dates);
                die;
            }
        }
     }
}

这是我的模特

class Blackout extends CalendarAppModel
{
   var $name = 'Blackout';
   var $useTable = false;
   function singleBlockWeekly($startDate,$endDate,$repeatEvery = array(),$freq)
   {
     /*my code here...brevity...*/
   }
}

所以我在这里只是在停电模型中调用singleBlockWeekly函数.我想知道即使在singleBlockWeekly函数上没有任何与SQL相关的代码,为什么也会收到奇怪的SQL错误？

对你的帮助表示感谢！谢谢！
