子句之間Laravel返回null

Question

我得到一個SQL在laravel這樣

$scheduleMap=array("schedule_id"=>$scheduleId); 
$scheduleConsume=DB::connection("mysql_report")->table("xxx") 
->where($scheduleMap) 
->whereBetween(DB::Raw("TO_DAYS(FROM_UNIXTIME(report_time))"),array(DB::Raw("TO_DAYS('".$startDate."')"),DB::Raw("TO_DAYS('".$startDate."')"))) 
->select(DB::Raw("SUM(imp_num) as imp_num")) 
->first(); 

我打印SQL作爲

select SUM(imp_num) as imp_num from `xxx` 
where TO_DAYS(FROM_UNIXTIME(report_time)) 
between TO_DAYS('2016-11-05') 
and TO_DAYS('2016-11-12') 

然後我嘗試在Navicat運行SQL，它工作得很好，但在laravel，它返回null。 我無法理解！我現在必須使用whereRaw。

試試這個:)

$scheduleConsume = DB::connection("mysql_report") 
        ->table('xxx') 
        ->where('schedule_id', $scheduleId) 
        ->whereBetween(
         DB::Raw("TO_DAYS(FROM_UNIXTIME(report_time))"), [ 
          DB::Raw("TO_DAYS('".$startDate."')"),DB::Raw("TO_DAYS('".$startDate."')") 
         ] 
        ) 
        ->select(DB::Raw("SUM(imp_num) as imp_num")) 
        ->first();
